The Strainsert 2-wire Loop Powered 4 to 20 mA Strain Gage Modules are specially designed compact, high performance strain gage analog signal conditioner modules. They are aimed at 350 Ohm sensor applications which require high measurement accuracy, resolution, and stability. The internal signal conditioner reduces interference in noisy environments and allows for longer cable runs. The module and sensor may be powered by a typical DC power supply. Outputs may be configured for either UniPolar or Bi-Polar operation.

The modules may be mounted inside of the Strainsert sensor body in either a single bridge, dual bridge, or biaxial configuration.
