Surface Mounting SSOP Packages (Twice Max.)Note: 1.We recommend that the suitability of solder mounting be verified under actual conditions.2.Tape cut SSOPs are packaged without humidity resis-tance. Use manual soldering to mount them.Manual Soldering (Once Only)Manually solder at 350°C for 3 s or less or at 260°C for 10 s or less.SSOP Handling Precautions<Humidity-resistant Packaging>Component packages can crack if surface-mounted components that have absorbed moisture are subjected to thermal stress when mounting. To prevent this, observe the following precau-tions.1.Unopened components can be stored in the packaging at 5to 30°C and a humidity of 90% max., but they should be used within 12 months.2.After the packaging has been opened, components can bestored at 5 to 30°C and a humidity of 60% max., but they should be mounted within 168 hours.3.If, after opening the packaging, the humidity indicator turnspink to the 30% mark or the expiration data is exceeded, bake the components while they are still on the taping reel, and use them within 72 hours. Do not bake the same com-ponents more than once.Baking conditions: 60±5°C, 64 to 72 hExpiration date: 12 months from the seal date(given on the label)4. f the same components are baked repeatedly, the tapedetachment strength will change, causing problems when mounting. When mounting using dehumidifying measures, always take countermeasures against component damage from static electricity.5.Do not throw or drop components. If the laminated packag-ing material is damaged, airtightness will be lost.6.Tape cut SSOPs are packaged without humidity resistance.Use manual soldering to mount them.AC ConnectionDC Single Connection DC Parallel Connection LoadLoadLoadLoadSolder type Preheating SolderingLead solderSnPb150°C60 to 120 s230 to 260°C10 s max.Lead-free solderSnAgCu150°C60 to 120 s245 to 260°C10 s max.Solder type Preheating SolderingLead solderSnPb140→160°C60 to 120 s210°C30 s max.Peak240°C max.Lead-free solderSnAgCu180→190°C60 to 120 s230°C30 to 50 sPeak260°C max.Solder type Preheating SolderingLead solderSnPb140→160°C60 to 120 s210°C30 s max.Peak240°C max.Lead-free solderSnAgCu150→180°C120 s max.230°C30 s max.Peak250°C max.5。

因测量结果取决于两个波段辐射功率之比，所以，辐射能量的部分损失对测量结果没有影响。
可克服传输介质有灰尘、烟雾、水汽，视场局部遮挡和测量距离变化造成的辐射能量衰减而引起的测量误差，特别适用于相对恶劣的测温环境。
金属热加工过程中，金属表面不可避免会快速氧化形成氧化层，氧化层会随温度变化脱落或者皴裂（例如轧钢生产线），皴裂氧化皮和金属本体形成间隙，使得氧化层的温度低于金属本体温度。
测温仪可以很好的克服因此引起的测量误差，使得生产工艺数据可靠且离散性小，便于工艺分析。

FTW31, FTW32Function and system designMeasuring principle An alternating voltage exists between the probe rods. As soon as a conductive liquid creates a connectionbetween the ground probe rod and, for example, the MAX probe rod, a measurable current flows and theLiquipoint T switches.With point level detection, the device switches back as soon as the liquid clears the MIN probe.With two-point control, the device does not switch back until the MAX and MIN probe is cleared.Using alternating voltage prevents corrosion of the probe rods and electrolytic destruction of the product.The material used for the tank walls is not relevant for measurement because the system is designed as a closed,potential-free circuit between the probe rods and the electronics.There is absolutely no danger if the probe rods are touched during operation.Measuring system Probes without an integrated electronic insert (separate instrument version) forone- or two-point detectionThe measuring system consists of:• FTW31, FTW32 with two/three rods or ropes• One or two Nivotester FTW325• Control units, switches or signal transmitters, e.g. process control systems PLC, relays, etc.Switch points, depending on the tank materialEndress+Hauser3Liquipoint T FTW31, FTW324Endress+HauserProbes without integrated electronic insert for multiple point detection The measuring system consists of:• FTW31, FTW32 with five rods or ropes • Two or three Nivotester FTW325• Control units, switches or signal transmitters, e.g. process control systems PLC, relays, etc.Switch points, depending on the tank materialProbes with integrated electronic insert (compact instrument version)The measuring system consists of:• FTW31 with rods or FTW32 with ropes and an electronic insert• Control units, switches or signal transmitters, e.g. process control systems PLC, relays, etc.Independent of the tank material!Note!The compact instrument version with three rods or ropes is always operated in s mode.Liquipoint T FTW31, FTW32Endress+Hauser 5InputMeasured variableResistance change between two conductors caused by the presence or absence of a conductive liquid.Measuring range (application)The measuring range is dependent on the mounting location of the probes.Rod probes can have a max. length of 4 m (13 ft), and rope probes can have a max. length of 15 m (49 ft). Input signalProbes covered => a measurable current is flowing between the probes.Probes uncovered => there is no measurable current flowing between the probes.OutputElectronic insert FEW52 (DC-PNP)Output signalThree-wire direct current versionPreferred in conjunction with programmable logic controllers (PLC).
