The MTT MS3910 Chassis-mounting Potentiometer Transmitter converts the resistance variation from a potentiometer sensor into a standard isolated DC output, giving position and level measurements based on a simple resistive element a clean interface into a process control system. Packaged in the compact chassis-mount format shared with the rest of the MS39-series, it is designed for high-density installations on MTT’s RC3900 chassis platform.
The input resistance range is selectable from 0-100Ω up to 0-10kΩ, so one transmitter model can be configured to match a wide variety of potentiometer sensors simply by setting the range rather than substituting a different unit. Dual output combinations of voltage and current are available to match the receiving equipment, zero and span are adjustable to fine-tune the reading, and isolation between input, both outputs, and power keeps the transmitted signal clean and protected from noise and ground loops.

Frequently Asked Questions
What is the MTT MS3910 used for?
It converts the resistance variation from a potentiometer sensor into a standard isolated DC output, giving position and level measurements based on a simple resistive element a clean interface into a process control system.
What potentiometer resistance range does it support?
Selectable from 0-100Ω up to 0-10kΩ, so one transmitter model can be configured to match a wide variety of potentiometer sensors by setting the range rather than substituting a different unit. Tell us your potentiometer’s resistance range and we can confirm the configuration.
What output options are available?
Dual output combinations of voltage and current are available to match the receiving equipment, with isolation between input, both outputs, and power keeping the transmitted signal clean and protected from noise and ground loops.
Can the reading be fine-tuned after installation?
Yes, zero and span are adjustable, allowing the output to be calibrated to the specific potentiometer and mechanical linkage in your application.
How do I know if the MS3910 is right for my application?
If you’re measuring position or level with a potentiometer sensor and need a high-density, chassis-mounted transmitter for a multi-channel panel, the MS3910 on an RC3900 base covers that. Send us your potentiometer’s resistance range and the output signal you need and we’ll confirm before you order.
