Mechanical drawing / connection

ES 5 K

  • LM = 60mm
  • Lt = 79mm
The zero point of the sensor, i.e. 4mA or 0V output signal, is at dimension Lm = 60mm.

For measurements with plus/minus range, the sensor must be preloaded so that the output dimension is Lm +2.5mm = 62.5mm.

For strain measurements, the sensor can be rigidly extended to 500m or 1000mm, resulting in an even better signal strength.


Standard: 3m cable, 4-wire, unshielded

Cable lengths of more than 100m are possible by using special low-impedance cable.
