Performance Features

The principle of the product:
TA-100A compact temperature transmitter is composed of reference unit, R/V conversion unit, linear circuit, reverse protection, current limiting protection, V/I conversion unit, etc. After the amplification of the thermal resistance signal, the nonlinear relationship between temperature and resistance is compensated by a linear circuit. After the V/I conversion circuit, a constant current signal of 4 ~ 20mA with a linear relationship with the measured temperature is output. Thermal resistance transmitter is a kind of temperature detector commonly used in middle and low temperature region.

Application field:
TA-100A compact temperature transmitter is suitable for water treatment control equipment, electrical industry, Marine hydraulic equipment, hydraulic and hydropower, chemical, petrochemical industry equipment and thermal coal boiler, pneumatic, hydraulic, cooling system, heating system, automation engineering, etc. The product is suitable for medium and low temperature area temperature detector.
