Intelligent and explosion proof temperature transmitter



WR-207 is integrated temperature transmitter uses PT100, N, K, J and other temperature sensing components, through the circuit processing module to convert the resistance signal into a standard 4-20mA current signal, widely used in chemical automatic control systems, and transmitted to Indicators, recorders and regulators for monitoring, regulating and controlling industrial systems. It not only saves expensive compensation wires cost , but also improves the anti-interference ability of signals during long-distance transmission. The transmitter is high precision, low power consumption, wide temperature range, stable and reliable operation, and is resistant to shock and moisture due to the silicone rubber sealing structure, which is suitable for use in harsh field environments.

Easy assembly and easy replacement

Good shakeproof and high precision

Wide measuring range (-200 ° C ~ 1600 ° C)

Fast thermal response time and long service life

High mechanical strength and good pressure resistance

Suitable Explosion proof area

In chemical plant, there are various flammable and explosive chemical

gases around the production site. It’s unsafe and easy to cause

environmental gas explosion if use common thermocouples,

it needs to use flameproof thermocouple as temperature

measurement instrument in these cases.
