TA-200B series armoured temperature transmitter

TA-200B Series

Armoured temperature transmitter

TA-200B armored temperature transmitter contains a thermal resistance/thermocouple temperature probe. The probe detection value changes with the temperature, and the circuit in the transmitter part converts it into a linear analog output. It has high precision, a wide range of measurement, imported thin film resistance components, reliable and stable performance and many other advantages, cast aluminum alloy, high temperature and high pressure resistance, suitable for electrical industry, heat medium boiler, cooling system and the vast majority of industrial automation control temperature measurement.

Performance Features

The theory of product:
TA-200B armored 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.

Application field:
TA-200B armored 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.

Features:
■ Simple wide installation, multi-range optional, a variety of specifications of the probe optional
■ Soft sheathed cable with anti-vibration measuring plug-in

■ Good mechanical properties, vibration resistance, impact resistance

■ Small measurement lag in thermal inertia

■ Compact structure, few moving parts, wide range (-200-1800℃).

■ High precision and repeatability, with temperature compensation.

■ Withstand pressure, shock and humidity, suitable for installation in harsh field environment.

■ Thermocouple temperature transmitter with cold end temperature automatic compensation function.

■ Thermal resistance, thermocouple signal input, 4-20mA or thermal resistance, thermocouple signal output
