SI 701WPBIHP

  • 4-20 mA Output
  • +15 VDC Operation
  • Low Cost
  • High Performance

The Columbia Models SI-701WPBI and SI-701WPBIHP are waterproof versions of Columbia's popular Model SI-701BI and SI-701BIHP. These waterproof sensors are designed with an output circuit configuration made for use with 4-20 mA data transmission systems used extensively in industrial installations in order to transmit data over long distances in rough environments.

The general purpose Model SI-701BI and high performance Model SI-701BIHP Inclinometers and optional waterproof cable assemblies allow remote tilt sensing in a variety of applications such as dam gate control, drawbridge control and platform stabilization. Consult the factory for customized versions of these sensors.
