海尔科技的pH电导性传感器说明书
Sensor FeaturesSensor housings are constructed of PEEK,a high performance thermoplastic that provides outstanding mechanical strength and chemical resistance. Multiple sealing materials are used to preserve sensor integrity over a wide range of applications.A large volume, dual junction saltbridge is used to maximize the in-service time of the sensor. The annular junction provides a large surface area to minimize the chance of fouling. Large electrolyte volume and dual reference junction minimizes contamination of the reference solution. The replaceable saltbridge allows for easy sensor regeneration.The reference element of this sensoris a second pH electrode immersed ina reference buffer solution. This glass reference system allows the sensorto be used in applications that poison conventional pH sensors.An integral preamplifier is encapsulatedin the body of the sensor. This creates a low impedance signal output which ensures stable readings in harsh environments, and maximize the distance between sensor and transmitter. Sensor diagnostics are used to alarm the user in the event of electrode breakage, lossof sensor seal integrity, or integral temperature sensor failure.Sensor electrodes can be user-specifiedto ensure measurement reliability and maximum sensor lifetime. The type of glass used in the pH electrode can be selected foroptimal performance. The metal electrode used for ORP measurements can be platinum or gold, depending on chemical makeupof the process solution.PHTX-45, transmittershown with PHE-45Pelectrode, both shownsmaller than actual size.Ordering Example:PHTX-45, pH transmitter, PHE-45P, electrode and PHA-4, buffer solution.SIMULATION features provide the user with complete control of the system output under any condition.Diagnostic messages provide a clear description of system condition, which eliminatesconfusing error codes that must be looked up in the operator’s manual.The flexible two-point and sample calibration options include auto-buffer recognition from thirteen built-inbuffer tables. Manual override of the automatic buffer values allows the user to customize calibration values. To ensure high accuracy, all calibration methods include stability monitors that check temperature and main parameter stability before accepting data.SpecificationsPHE-45P and ORE-45P Sensor SpecificationsSensor Cable: 3 m (10’) Measuring Range:PHE-45P: 0 to 14.00 pH ORE-45P: -1000 to 2000 mVSensitivity: 0.002 pH, 0.2 mV (ORP)Stability: 0.02 pH or 2 mV per 24 hours, non-cumulative Wetted Materials:PHE-45P: PEEK, ceramic, titanium, glass, FKM, EDPM (316 stainless steel with 316SS body option)ORE-45P: PEEK, ceramic, titanium, glass, FKM, EDPM, platinum or gold Temperature Compensation: Pt1000 Sensor Cable: 6 Conductor plus 2 shields Temperature Range: -5 to 95°C (23 to 203°F)Pressure Range: 0 to 100 psig Maximum Flow Rate: 3 m (10’) per secondSensor to Transmitter Distance: 914 m (3000’)Mounting Options: 1 NPT convertible Weight/Shipping Weight: 0.45 kg (1 lb)P HTX-45 Transmitter SpecificationsEnclosure: NEMA 4X, IP65,polycarbonate, stainless steel hardware, weatherproof and corrosion resistant, 112 H x 112 W x 89 mm D (4.4 x 4.4 x 3.5”)Mounting Options: Wall, panel, pipe, Din rail, integral-sensorConduit Openings: 2-PG9 openings, 1 to 1 NPT center opening, cord grips and plug includedWeight/Shipping Weight: 0.45 kg (1 lb)Display: Large, high-contrast,super-Twist (STN) LCD; 4-digit main display with 19.1 mm (0.75”) seven-segment character, 12-digit secondary display,7.6 mm (0.3”) 5 x 7 dot matrix character Keypad: 4-key membrane type with tactile feedback, polycarbonate with UV coating, integral EMI/static shield and conductivity coated window Ambient Temperature:Service: -20 to 60°C (-4 to 140°F) Storage: -30 to 70°C (-22 to 158°F)Ambient Humidity:0 to 95%, non-condensingLocation: Designed for hazardous and non-hazardous areasEMI/RFI Influence: Designed to EN61326-1Voltage Range:16 to 35 Vdc (two-wire device)Output Isolation: 600 V galvanic isolation Transmitter Cable Type: Belden twisted-pair, shieldedFilter: Adjustable 1 to 99 seconds additional damping to 90% step input Temperature Input: Selectable Pt1000 or Pt100, automatic compensationPHE-45P Performance SpecificationsDisplayed Parameters: Main Input: 0 to 14.00 pH; Sensor Voltage: ±500 mV; Loop Current: 4 to 20 mA; Sensor Temperature: -10 to 110°C (14 to 230° F)Main Parameter Range: 0 to 14.00 pH Input Impedance: Greater than 1013 ΩRepeatability: 0.1% of or better Sensitivity : 0.05% of span Non-Linearity: 0.1% of span Stability: 0.1% of spanper 24 hours, non-cumulative Warm-Up Time: 4 seconds to rated performanceSupply Voltage Effects: ±0.05% span Transmitter Response Time: 4 seconds to 90% of step input at lowest settingTemperature Drift:Span or zero, 0.02% of span/°C Sensor to Transmitter Distance: 914 m (3000’) w/preamp, 9.1 m (30’) w/o preamp。

Protocol is widely used to establish master-slave communication between intelligent devices or sensors.A MODBUS message sent from a master to a slave contains the address of the slave,the function code(e.g.'read register'or'write register'),the data,and a check sum(LRC or CRC).The sensor is RS485interface with Modbus protocol.The default serial communication settings is slave address1,modbus rtu,9600bps,8databits and1stop bit.All communication settings can be changed with modbus command,and take effective after re-power up the sensor.Following modbus function code are supported by

★信号输出： RS485（ Modbus/RTU 协议）。
★方便连接到 PLC、DCS、工业控制计算机、通用控制器、无纸记录仪器或触摸屏等第三方设备。
双高阻抗差动放大器，抗干扰强，响应速度快。
★专利的 pH 探头，内部参比液在至少 100KPa（1Bar）的压力下，极其缓慢的从微孔盐桥中渗出，其正向渗出持续20 个月以上。
这样的参比系统非常稳定，电极寿命比普通工业电极成倍延长。
★易于安装：3/4 英寸 NPT 螺纹（管螺纹），便于安装在管道和罐体。
探头和显示部分可分开，通过电缆连接。
★ IP68 防护等级。

在线水质PH数字传感器；
本系统可以在线监测并直接显示水质中PH值；测试稳定准确，操作界面友好，使用方便。
一．产品参数
二．硬件连接
1．USB数据采集器连接PC
2．RS485数字传感器（通过标准的modbus协议可以直接用于水质监测，环境监测，教育培训，工厂等工业场合应用，无线物联网应用）
3．多参数水质，土壤离子分析测试软件
4．附件；无
5．校准；用PH7.0的标准液和PH4.01的二种标准液，在二种的标准液中去校准传感器。
校准方法见软件测试界面。
三．软件测试界面
1．打开软件会看到如下界面，如果此传感器没有校准过，那必须先开始校准，打开校准菜单，在测量菜单下选择校准，然后点击PH,DO(溶解氧)校准。
校准界面如下；先将PH传感器放入PH7.0的标准液中约1-2分钟，然后点击校准和确定，然后在去离子水中清洗传感器后用纸巾擦干，将传感器放入PH4.01的标准液中，约1-2分钟，然后点击菜单校准和确定，校准完成，清洗并擦干传感器后，可以以传感器来测量标准液来测试校准的准确性，可以重复以上校准程序来获得最高精度的校准，现在可以用传感器去检测未知PH的溶液了。
测量界面如下，直接点击PH测量菜单，可以获得未知PH溶液的PH值。
四；传感器的保存；
短期保存；
将传感器浸入PH4.01的标准液中保存。
长期保存；
把传感器浸泡在有PH浸泡液的浸泡瓶或放入传感器配带的有浸泡液的保护套中。
五；安装方式；
前螺纹安装，可以旋入管道中，后螺纹安装，可以直接沉入水体中，见附图；。
