MT2187 RTD input, two-wire temperature transmitter (isolated)

· Pt100, Cu50 and other RTD inputs, 4~20mA output, and electrical isolation between input and output. Adjust the potentiometer with zero and full scale calibration.
· MT2187 two-wire temperature transmitter, thermal resistance signal input, after isolation, converted into a standard 4 ~ 20 mA output signal.
· Electrical isolation between input and output.
· Adjust the potentiometer with zero and full scale calibration.
· Two-wire transmission mode (The power supply does not output the signal as a common two wires).
· Compact structure design, which can be directly installed in the standard junction box of the temperature sensor head to form an integrated structure.
