The principle of the product:
The TA-300A intelligent 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. The RTD transmitter is a temperature detector commonly used in the medium and low temperature range.
Features:
■ Local display, easy observation
■ Soft sheathed cable with an anti-vibration measuring plug-in
■ Extremely high accuracy and repeatability with built-in temperature compensation
■ Application-specific insertion length
■ Compact structure, few moving parts, cast aluminium alloy housing
■ Pressure-resistant, shock-proof and moisture-proof, suitable for harsh field environments
■ Remote information management of transmitter model, graduation/range via HART modem, with configuration, variable detection, calibration and maintenance functions
■ Low thermal inertia, small measurement lag
■ Long service life
Application field:
The TA-300A intelligent 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, high and low temperature ranges.
