Product details

Performance characteristics

Principle:
TA-300A Intelligent Temperature TransmitterIt consists of a reference unit, R/V conversion unit, linear circuit, reverse protection, current limiting protection, V/I conversion unit, etc. After the thermal resistance signal is converted and amplified, the non-linear relationship between temperature and resistance is compensated by a linear circuit. After the V/I conversion circuit, a constant current signal of 4-20mA is output, which is linearly related to the measured temperature. Thermal resistance transmitter is the most commonly used temperature detector in medium and low temperature areas.


characteristic:
On site display, convenient for observation
Soft sheathed cable with anti vibration measurement plug-in
Extremely high precision and repeatability, with built-in temperature compensation

Application specific insertion length

Compact structure, few moving parts, cast aluminum alloy shell

Pressure resistant, shock resistant, moisture resistant, suitable for installation and use in harsh on-site environments

The model and calibration of the transmitter can be determined through a HART modem/Remote information management, configuration, variable detection, calibration, and maintenance functions for measuring range

In terms of thermal inertia, the measurement lag is small

long service life



Application field:

TA-300A Intelligent Temperature TransmitterSuitable for water treatment control equipment, electrical industry, ship hydraulic equipment, hydraulic and hydroelectric, chemical, petrochemical industry equipment and thermal coal boilers, pneumatic, hydraulic, cooling systems, heating systems, automation engineering, etc; The product is suitable for temperature detectors in high, medium, and low temperature areas.
