Welcome To Meacon Automation Co.,Ltd
Intelligent temperature transmitter for RTD, TC signal input, 2-wire 4-20mA analog output. This smart temperature transmitter supports the measurement of millivolt signals and resistance signals.
High precision temperature transmitter module is a two-wire temperature transmitter, it can receive pt100 RTD and all kinds of thermocouple input, can be directly installed in the sensor junction box, the temperature sensor resistance or millivolt signal into a standard 4-20ma, or 0-10ma, 1-5v and other signals, and then remote transmission to other secondary meter supporting the use. It has the characteristics of accurate signal, remote transmission (maximum 500 meters), good accuracy, anti-interference, good stability, maintenance-free, etc.. Its conventional accuracy is up to 0.25%.
