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.

Frequently Asked Questions
What is the MTT MS3710 used for?
It reads the resistance of a potentiometer, such as a position or level sensor with a wiper output, and converts it into a standard DC current or voltage signal for control and monitoring equipment.
What range of potentiometers does the MS3710 accept?
Resistance ranges from 0-100Ω up to 0-10kΩ, covering most common position and level potentiometers.
Why does a low measuring voltage matter?
The MS3710 uses a gentle measuring voltage of about 0.5V across the potentiometer, so the sensor experiences almost no self-heating, which helps preserve its accuracy and service life over long-term use.
Can the MS3710 drive two separate systems from one potentiometer?
Yes, in its dual-output configuration — both outputs are isolated from each other, the input, and the power supply, so one potentiometer can feed a control loop and a separate monitoring or logging system at the same time.
How do I know if the MS3710 is right for my potentiometer sensor?
Send us your potentiometer’s total resistance and the output signal your receiving equipment needs, and we’ll confirm the right configuration.
