Lead sketch2 .Following conditions must be avoided2.1 Water CondensationIndoor conditions, slight water condensation will influence sensors’ performance lightly. However, if water condensation on sensors surface and keep a certain period, sensors’ sensitiv e will be decreased.2.2 Used in high gas concentrationNo matter the sensor is electrified or not, if it is placed in high gas concentration for long time, sensors characteristic will be affected. If lighter gas sprays the sensor, it will cause extremely damage.2.3 Long time storageThe sensors resistance will drift reversibly if it’s stored for long time without electrify, this drift is related with storage conditions. Sensors should be stored in airproof bag without volatile silicon compound. For the sensors with long time storage but no electrify, they need long galvanical aging time for stability before using. The suggested aging time as follow:Stable2.2.4 Long time exposed to adverse environmentNo matter the sensors electrified or not, if exposed to adverse environment for long time, such as highhumidity, high temperature, or high pollution etc., it will influence the sensors’ performance badly.2.5 VibrationContinual vibration will result in sensors down-lead response then break. In transportation orassembling line, pneumatic screwdriver/ultrasonic welding machine can lead this vibration.2.6 ConcussionIf sensors meet strong concussion, it may lead its lead wire disconnected.2.7 Usage Conditions2.7.1For sensor, handmade welding is optimal way. The welding conditions as follow: ● Soldering flux: Rosin soldering flux contains least chlorine ● homothermal soldering iron ● Temperature ： 250℃ ● Time ：less than 3 seconds2.7.1If users choose wave-soldering, the following conditions should be obey: ● Soldering flux: Rosin soldering flux contains least chlorine ●Speed: 1-2 Meter/ Minute● Warm-up temperature ：100±20℃ ● Welding temperature ：250±10℃● One time pass wave crest welding machineIf disobey the above using terms, sensors sensitivity will be reduced.。

Honeywell ADT-222C 世界领先的空气数据测试仪说明书

/Honeywell-ADT-222C-Air-Data-Test-Sets.aspxare safe, because the ADT -222C inter-faces are compatible with its predecessor.The ADT -222C improves the productivity of any air data test facility, whether labora-tory, shop, production or even flight line. It dramatically reduces manual test times,and provides further savings in automated test. Although specifically designed to test Honeywell-developed air data sys-tems, this versatile precision pressure controller is also suited to test other sys-tems and will be an asset to your air data test facility.The ADT-222C:Better than the bestThe Honeywell air data tester ADT -222B,once heralded as the most efficient, accu-rate and dependable pneumatic test equipment avilable in the industry has been retired. Taking its place is Honeywell’s new ADT -222C, providing many new features and improvements while maintaining the ease-of-use and reli-ability you expect from a Honeywell sys-tem. And rest assured that any invest-ments you may have made in installed software and training for your ADT -222BOperational flexibilityThe ADT -222C speaks theoperator’s language by providing meas-urement or control in either English,metric or various other units for altitude,airspeed, Mach, absolute pressure or differential pressure functions. When it is used as a pressure controller, desired pressure or altitude, airspeed and Mach values are entered via a new, easy-to-use keypads on the front panel of the unit and information is displayed on state-of-the-art vacuum fluorescent dis-plays. Control to newly selected values is initiated by a single push-button switch, negating the need for multiple keystrokes which many competitive products require. Dynamic test varia-tions can be selected on the front panel and applied to the Ps or Pt channel.Moreover, the ADT -222C allows for both dry air or nitrogen operation. So, there’s no longer a need for separate calibra-tion — one less variable for you to con-tend with.Honeywell’s patented tuning fork control valve outperforms all competitive pres-sure controllers by having two independ-ent electronically adjustable nozzle flow areas. This arrangement provides 100percent vacuum pump efficiency and permits the ADT -222C to operate with only a single vacuum pump, whilereducing gas consumption and increas-ing pneumatic load driving capability. The high-performance valve allows the ADT -222C to drive 60 cu. in. volumes at 40,000 ft./min. up to 90,000 ft., and 500kts./min. up to 1,000 kts. with a single 300 liter/min. vacuum pump, or 200 cu.in. volumes over the same range with two 50 liter/min. vacuum pumps.The ADT -222C maintains precise elec-tronic range rate control over these operating ranges. Its electrically con-trolled pressure regulation valves pro-vide high speed control re-sponse, with resolution and stability sufficient to resolve a one-foot change in altitude at60,000 ft.Tuning fork control valveThe ADT -222C is smaller and lighter than its predecessor and consumes less power. Currently a bench unit is avail-able; however, portable and flight line units are planned, as is remote opera-tion. In addition to ADT -222B modes, a Mach control mode is available with the ADT -222C and a new profile mode can store up to 10 profiles — a considerable time-saver. Perhaps most significant is the use of Honeywell’s new silicon pres-sure sensor which extends the calibra-tion cycle to a minimum of six months.Electronic slew controlAn automatic slew control system maintains thecommanded flight profile regardless of the pneumatic load volume or vacuum pump size. The ADT -222C control system detects the side (Ps or Pt) with the largest pneumatic load and reduces the pressure rate on the oppo-site side by the correct ratio. Pneumatic loads greater than 1,000 cu. in. may be driven while still maintaining the desired flight profile. A commandable slew sys-tem can be activated for supersonic equipment to reduce test time by allow-ing the ADT -222C to proceed to the newpressure at full control valve capacity.Simplified maintenanceDisplay components, sensors, electronic cards andsubassemblies are packaged for simple maintenance. Also, plug-in interchangeable, solenoid and control valves mount directly onto a custom tai-lored pneumatic manifold system, which provides higher reliability by eliminating many pneumatic connections. A power-on self-test verifies the initial integrity of the entire system, and the processor continues to monitor certain key func-tions during normal operation. Last but not least, the ADT-222C allows a mini-mum of six-months calibration cycle and fully automatic calibration via the IEEE 488.2 interface.IEEE Interface (ASCII)An IEEE 488.2 interface card is included in theADT-222C for a direct data link to a computer or an ATE. This feature mini-mizes operator intervention required to run an entire flight profile. Additionally, RS-232 and RS-422 interfaces will be supported.Honeywell’s siliconpressure sensorOne of the key contributors to theADT-222C’s superior performance isHoneywell’s silicon pressure sensor.In addition to excellent overall accuracy,Honeywell’s silicon sensor has virtuallyzero non-correctable error and unprece-dented stability. Moreover, the sensor’sreliability is superior to others since itrequires no temperature stabilizationhardware.The silicon pressure sensor is a memberof the high-accuracy pressuresensor family used in Honeywell world-class air data avionics.Meeting the savings testAdd up the man-hour savings, theaccessory hardware savings and thehigher quality end product made possi-ble by using the ADT-222C. Result:cost-effectiveness all the way down theline. Testing and maintenance cost sav-ings alone can easily justify using theADT-222C to replace existing mercurymanometry, outdated servo-based orlower performance air data test systems.The ADT-222C. More utility, more capaci-ty, at a considerable cost savings over itspredecessor.Silicon SensorADT-222C SpecificationA60-0813-000-000September 2004© 2004 Honeywell International Inc.Find out moreTo find out more about Honeywell’s ADT -222C, please email us at ***************************or contact:Aerospace Electronic Systems Air Transport Systems Honeywell International Inc.21111 North 19th Avenue Phoenix, AZ 85027Tel: 602.436.2824The ADT -222C shall maintain the accu-racy and repeatability stated in the fol-lowing table whether in control or meas-ure mode.

清晰通信 MS-702 双通道主站说明书

The MS-702is a one-rack-space, two-channel main station with aregulated 1.2-amp “fail-safe” power supply, individual channel short-circuit protection, and a versatile intercom monitoring system. It supports two intercom channels with up to 40 beltpacks or 10 speaker stations. It features Clear-Com’s excellent speech intelligibility in both high- and low-noise environments.Monitoring SystemThe MS-702 can monitor intercom activity on one or both channels with individual listen-level controls. Monitoring intercom activity is possible through a headset or the internal loudspeaker. The high-sensitivity internal speaker provides intelligible communication in the typical active production environment.Talk SelectionThe MS-702 contains mic preamps with limiters, and speech-shaping circuits for enhanced intelligibility. An individual electronic momentary/latching talk button is provided for each channel. These buttons lightdimly when latched - blue-color LED while in stand-by and amber-color LED when latched. The channels may be accessed separately or simultaneously without tying them together. An optional gooseneck mic is available. Announce OutputFor paging applications, the MS-702 provides a balanced, line-level output signal to a 1/4-inch TRS connector on the rear panel. The front panel “Announce” button activates the output and the Announce relay. The relay circuit, on a separate 1/4-inch TRS connector, is typically used to mute control-room monitors during live announcements.Visual And Audible SignalingVisual “call” signaling attracts the attention of operators who have removed their headsets or turned off their speakers. Call buttons for each channel signal all stations on that party line by flashing brightly. Along with the visual signal, the station’s speaker will emit an audible signal if the remote station operator holds the Call button for more than 2 seconds.Remote Mic Kill (RMK)The MS-702 is equipped with a global RMK button. It will turn off the micro-phone talk circuits of all Clear-Com beltpacks in the system, eliminating extraneous noise from the “open” headset microphones.Program InputThe MS-702 accepts a line-level external program input for monitoring in the headset and speaker, and/or mixing with intercom audio on either or both channels. When Interrupt is selected, the program signal is interrupted when the Talk button is pressed.Power Supply & System ProtectionThe MS-702 provides visual indication of power supply conditions. In the event of a short circuit or current overload on a channel, that channel will shut down while the other one continues to operate.

NPTOptional HMIThe optional HMI Service/Display unit is used for commissioning and quick on-site setup and is easily mounted on the AKS 4100U.The service unit supports mulitple languages in both SI and US units.Measuring principle (Cable and Coaxial)The AKS 4100U electronic converter emits low-intensity, high frequency electromagnetic pulses with a width of approximately 1 nanosecond, which travel at the speed of light along the probe (wire or coaxial cable) down to the liquid surface.The pulses are reflected by the liquid surface, guided back along the probe, and received and analysed by the AKS 4100U electronic converter and then converted into a liquid level reading. This method is called time domain reflectometry (TDR) or guided microwave.The dielectric constant, εr, of the liquid is a key parameter and has a direct impact on the degreeof reflection of the high frequency electromagnetic pulses. Liquids with high εr values, such as ammonia, produce strong reflections, while liquids with low εr values, such as CO2, produce weak reflections.As long as the εr value of the liquid refrigerant is higher than 1.2, AKS 4100U can detect the liquid level and level measurement accuracy is not affected.If the temperature condition in the standpipe/vessel is known, a constant (dielectric constant of the refrigerant gas) can be entered (parameter 2.5.3 GAS EPS.R), in order to obtain improved Top and Bottom Dead Zone values.Refer to pages 7 to 8 for Measuring range of AKS 4100U - CABLE version and COAXIAL version.For details of gas constant values for different temperatures and refrigerants plus the procedure for entering these via the HMI, refer to pages 17 to 18.Main technical data (see a complete list of all technical data on page 11)Supply Voltage14 – 30 V DC.
