Mini Digital Temperature Transmitter Strong Thermal Resistance Capability

Mini Digital thermal resistance temperature transmitter temperature transducer
WR-203 Series temperature transmitter is composed of three parts as temperature sensor, compensation circuit and switching circuit. It has the advantages of stable performance, high sensitivity, and strong reliability. It can be widely used in automation temperature control system, such as metallurgy, machinery, petroleum, electricity, chemical industry, light industry, textile, building materials and so on.

Work principle
The thermocouple (resistance) measure the changes of thermal
power (resistance) when working, which will produce unbalance
signal through the temperature transducer’s bridge, and the
signal will be amplified and converted into 4-20mA DC signal to
the instrument, then the instrument will display the corresponding
temperature value.

Typical application
This series products is used to measure the temperature of the surface of liquid, steam, gas and solid under -50 to +600℃. It is suitable for temperature measurement in water supply, hydraulic pressure, cooling, heating system industry and automatic control.
