MTT MS3706B Slim Plug-In Strain Gauge Transmitter

The MTT MS3706B is a slim plug-in strain gauge transmitter tuned for low-output bridge sensors, resolving spans as narrow as under 1mV where a standard strain gauge transmitter would need a much larger signal to work with. It powers a strain gauge, load cell, or pressure sensor bridge directly, reads the low-level millivolt signal, and converts it into one or two isolated DC outputs suitable for standard control and monitoring equipment.

Where a dual-output configuration is used, both outputs stay isolated from each other, the input, and the power supply, letting one bridge sensor 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 MS3706B 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.
