MT1188 Thermocouple input, two-wire temperature transmitter (non-isolated)

· Thermocouple input such as K, E, S, B, 4~20mA output, no electrical non-isolation between input and output. Adjust the potentiometer with zero and full scale calibration.
· MT1188 two-wire temperature transmitter, thermocouple signal input, converted to 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.
