Details

MT1187 RTD input, 2-wire temperature transmitter (isolated)

· Pt100, Cu50 and other RTD inputs, 4~20mA output, no electrical isolation between input and output. Adjust the potentiometer with zero and full scale calibration.
· MT1187 two-wire temperature transmitter, thermal resistance signal input, converted into a standard 4 ~ 20 mA output signal.
· There is no electrical isolation between the input and output. It is a low cost two-wire temperature transmitter.
· 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.
