Sell Pors-TTRG RTD Transmitter
TTRG series RTD transmitter are used to receive Pt100 or Cu50 input, after transmission export standard DC 4-20mA signal.
Two wire 4-20mA output (power supply and signal share the two wire), output current is in linearity with the measured temperature. With Integration structure, the transmitters are generally assembled in standard terminal box of the temperature sensor.
◆ Features
Pt100 or Cu50 input;
Isolated two wire 4-20mA output;
With zero and span adjustor of the output signal;
High accuracy transmission, linear calibration;
Uniform apperance & structure, small volume, light;
Suitable to be assembled in terminal box of the sensor;
Also can be installed in instrument panel as signal converter independently;
Input/output is electromagnetic isolated;
