Instrument Overview
The YGQW7761 is a field-mount, DIN Form A head-mounted temperature transmitter unit. It is used with industrial thermocouples and RTDs and uses a two-wire transmission system (where the two wires serve as both power supply and signal output lines).
It converts industrial thermocouple and RTD signals into a linear 4~20mA output signal related to the input signal or temperature signal. It provides flexible and reliable performance in process environments. Compared to directly connecting the sensor, it reduces the need for expensive extended wiring and multi-port devices, thus reducing overall installation costs and fully leveraging the benefits of the complete temperature point solution.
