All TMI Strain Gaged Tension Transducers and Load Cells are full bridge 350 ohm or 1000 ohm sensors. They require an electronic signal conditioning module. This is typically a Digital Panel Meter with Display or Strain Gage Amplifier module.  These units must provide the sensor's excitation voltage and be able to process the mV/V signal from the sensor.
TMI does not use proprietary strain gage elements that require unique electronic signal conditioning units only available from a single source.  Our sensors are compatible with strain gage indicators readily available world wide.  We offer indicators to meet the needs of a wide range of user applications from display only to tension control outputs with data acquisition communications.  The units above will provide excellent resolution and stability for your tension measurement application.

All of the strain gage signal conditioners shown above provide the necessary sensor excitation voltage. The signal from the tension sensor is processed and converted to a digital display of the tension value as well as various options for tension control outputs. The Tension Sensor calibration is accomplished with known loads for accurate dynamic tension data.  All Tension Sensor Systems (sensor + indicator) are calibrated and tested in our lab.  A complete user manual is provided with all necessary drawings and indicator parameter settings.
