SI 701BC

  • High Accuracy
  • +/-15 VDC Operation
  • Low Cost
  • High Performance

The Columbia Models SI-701BC and SI-701BHPC are electronic tilt sensors based upon force balance accelerometer technology. They produce a high level low impedance output proportional to the sine of the tilt angle. Unique electronic damping and desensitization circuitry allows tilt measurements in strong vibration and shock environments.

These inclinometers are self-contained requiring no additional signal conditioning in most applications. The Model SI-701BC is well suited for many OEM and industrial applications. The Model SI-701BHPC uses the Columbia patented HP suspension system and provides added accuracy and ruggedness. Both sensors incorporate a convenient 4-pin connector and are intended for applications such as platform stabilization, surface mapping and measuring tilt angles in remote locations. Consult the factory for customized versions of these sensors.
