SensoTrans DMS A 20220

Strain Gauge Transmitter

The universal SensoTrans DMS A 20220 strain gauge transmitters provide connection possibilities for all standard strain gauge force transducers and strain gauge load cells in full bridge configuration. They can be flexibly adapted to the respective measuring task by the user via DIP and rotary encoder switches or a “teach-in function“. 3-port isolation with protective separation up to 300 V AC/DC according to EN 61140 ensures optimum protection of personnel and equipment as well as unaltered transmission of measurement signals. The SensoTrans DMS A 20220 offer maximum performance in the smallest of spaces. Adjusting the zero point and sensitivity to the individual strain gauge sensor is particularly convenient using the “teach-in function“ just at the push of a button on the front of the device. Sensors with known characteristics can be very easily calibrated using 4 rotary encoder switches and 8 DIP switches.Special measuring tasks can be solved with SensoTrans devices that Knick configures according to individual specifications. Fixed-range devices without switches are used, for example, when manipulations or mix-ups must be precluded.

    • Easy, without tools, using 4 rotary and 8 DIP switches
  • Calibrated range selection
    • No complicated trimming
  •  Convenient adjustment
    • Zero point and sensitivity are directly adjusted “at the push of a button“
      using the teach-in function
  • Protective separation according to EN 61140
    • Protection of maintenance staff and subsequent devices against
      excessively high voltages up to 300 V AC/DC
  • High accuracy due to innovative circuit design
  • Minimum space consumption in the enclosure
    • Modular housing: just 6 mm wide
    • More transmitters per meter of DIN rail
  • Low-cost assembly
    • Quick mounting, convenient connection of power supply through DIN rail bus connectors
