MTT MS3710 Slim Plug-In Potentiometer Transmitter

The MTT MS3710 is a slim plug-in potentiometer transmitter that reads the resistance of a potentiometer, such as a position or level sensor, and converts it into one or two isolated DC outputs. A gentle measuring voltage across the potentiometer means the sensor itself experiences almost no self-heating, helping preserve its accuracy and service life over long-term use.

Where a dual-output configuration is used, both outputs stay isolated from each other, the input, and the power supply, letting one potentiometer feed a control loop and an independent monitoring or logging system at the same time. Like the rest of the plug-in transmitter range, the MS3710 clips into its own socket base so the unit can be swapped for calibration or replacement in seconds without disturbing the field wiring, and flexible AC or DC power plus wall or DIN rail mounting make it easy to fit into an existing panel.
