The principle of the product:
The TA-200A armoured temperature transmitter is composed of a reference unit, an R/V conversion unit, a linear circuit, reverse-connection protection, current-limiting protection and a V/I conversion unit. After the RTD signal is amplified and converted, the non-linear relationship between temperature and resistance is compensated by the linear circuit; the V/I conversion circuit then outputs a 4-20mA constant-current signal that is linear with the measured temperature.
Features:
■ Easy installation, multiple ranges and various probe specifications available
■ Soft sheathed cable with an anti-vibration measuring plug-in
■ Good mechanical properties, vibration and shock resistance
■ Low thermal inertia, small measurement lag
■ Compact structure, few moving parts, wide range (-200-1800℃)
■ Extremely high accuracy and repeatability with built-in temperature compensation
■ Pressure-resistant, shock-proof and moisture-proof, suitable for harsh field environments
■ Thermocouple transmitter features automatic cold-junction temperature compensation
■ RTD and thermocouple signal input, 4-20mA or RTD/thermocouple signal output
Application field:
The TA-200A armoured temperature transmitter is suitable for water treatment control equipment, the electrical industry, marine hydraulic equipment, hydraulic and hydropower, chemical and petrochemical equipment, as well as heat medium boilers, pneumatic, hydraulic, cooling and heating systems and automation engineering. It is suitable for temperature detection in the medium and low temperature range.
