MTT MS3110 Terminal Block Type Potentiometer Transmitter

The MTT MS3110 terminal block potentiometer transmitter tracks the changing resistance of a potentiometric sensor and delivers it as two independent, isolated DC outputs from a single unit — useful when a position, level, or travel measurement needs to reach both a control loop and a separate recorder or indicator. Full isolation between input, both outputs, and power keeps every connected device electrically separate.

A choice of AC or DC power lets it fit panels without a dedicated low-voltage supply, and the DIN-rail housing mounts right where the potentiometer wiring terminates. Independent zero and span adjustments on each output let a technician set the working resistance range to match the sensor travel without disturbing the sensor itself.

It suits applications that need one potentiometric measurement — valve or damper position, float-type level — distributed to two separate systems, panels without a dedicated low-voltage bus, or any critical position measurement where redundant isolated outputs add reliability.
