WZP Series platinum thermistor elements
One、summary

The platinum thermistor is an accurate one、sensitive、Stable temperature sensor。Platinum thermistor elements are made of micro ceramic tubes、The temperature sensing element is made of the detachable coil of platinum thermal resistance wire wrapped in the hole，Because the temperature sensor can be made quite small（Small outer diameter can be achievedФ1.6～Ф0.3mm）Therefore, it can be made into various micro temperature sensor probes。Can be used for-200～+420℃Temperature in range。

WZPSeries platinum thermistors according to the new standard of ChinaJB/T8622-1997Production。Due to the small structure of this series of products，Wide application range、Good reliability、The thermal response time is short，It can form many varieties、Multi specification series products for petroleum、chemical industry、power station、metallurgy、light industry、food、spin、medical and health work、scientific research、Agriculture and machinery industry to provide a new generation of high quality products。
Two、working principle

Platinum thermistor as a temperature sensor，It works under the action of temperature，The resistance of platinum resistance wire changes with temperature。The relationship between temperature and resistance is close to linear，The deviation is very small and increases with time，The deviation can be ignored，And the electrical performance is stable。

notes:① AThe level tolerance does not apply tot ?650℃Temperature range of，It is not suitable to use two-wire system。
2.Self heating effect

The large measurement current allowed for platinum resistance is5mA，The resulting temperature rise is not greater than0.3℃
