SR- intelligent temperature transmitter is a powerful and intelligent two-wire temperature transmitter with wide
application. It is based on microprocessor, designed for process control. It can be used together with all kinds of
temperature sensors, weighing transducer and potentiometer. It is suitable for different measurement range and
various kinds of sensors, such as all kinds of heat resistance and thermocouple, millivolt or ohms signal (please
refer to the functional specification sheet for more details). Therefore, the original temperature transmitter installed
on site with different specification can be replaced by SR. This will significantly shorten calibration, maintenance
and training time, reduce the demand for spare parts. Because it has intelligent setting up feature, so you need not
to know the measurement and control parameters in advance.
Features
* Input and output signal isolation, strong anti-interference and radio frequency interference ability.
* Automatic diagnosis and failure alarm output function.
* Explosion proof, waterproof and essential safety.
* Basic accuracy 0.01%, input circuit automatically zero adjustment to ensure long stability.
* Optional ultra-low temperature (70 °C ~ ±45) OLED displays, built-in heat resistance and thermocouple linear curve.
* Two-wire 4-20 mA output superposition digital signal (HART protocol), can output 4~20mA signal proportional
to different temperature range, and adjust local or remote parameters through handheld terminal or computer uses
digital communication. Also parameters can be adjusted by instrument button itself.
