Coupling installation PT1000 platinum thermal resistance price credit enterprise is recommended

Temperature sensor temperature

temperature temperature sensor selection is mainly based on the measurement range. When the measuring range is expected within the total range, can choose platinum resistance temperature sensor. Narrower range usually require basic resistance temperature sensor must have a fairly high, in order to get enough resistance change. Thermistor provided enough resistance change makes these sensitive element is very suitable for narrow measuring range. If the measuring range is quite large, thermocouple more applicable. Will also include freezing in this range, because of the thermocouple indexing table is based on temperature. Known within the scope of linear temperature sensor also can be used as a selection of the temperature sensor of strings attached.

1. Temperature of the temperature sensor protective

temperature temperature sensors in the use of harsh conditions, the temperature sensor of waterproof, dustproof, moisture and prevent collision requirements, such as new sensitive electronic temperature temperature sensor using the micro assembly ( MPT） Technology and exquisite of laser seal welding, the conventional protection IP65, input type temperature sensor temperature can reach IP68 protection grade, can be used fully in the water. Have special requirements to when ordering please specify.

2. Temperature of electric temperature sensor select

temperature sensor temperature value can be converted into electricity signal, temperature measurement and control system of transmission to the instrument or PLC. Gen gold electronic temperature temperature sensors can provide: PT100 temperature signal; Current mode: 4-20 ma; Voltage type: 0-5 VDC, 1-5 VDC, 0. Five to four. 5 v, 0 to 10 VDC signal types.

the maintenance of the temperature sensor temperature

no matter under what circumstances, the power line and control line shall be twisted up and close degree 50 r/m, if the temperature sensor signal lines need to extend, the sealed cable junction box should be adopted. If there is no such a junction box, and use cable and cable direct docking ( Soldering end) , should be sealed container special attention, good insulation resistance shall be checked after, and up to standard, 2000 - — 5000M) Should, when necessary, to calibrate the temperature sensor. If the signal cable is very long, and to ensure the high accuracy of measurement, should consider adopting cable compensation circuit with relay amplifier.
