SI 702AIHP Biaxial Force Balance Inclinometer
- 4-20 mA Output
- +15 VDC Operation
- Low Cost
- High Performance
Columbia Models SI-702AI and SI-702AIHP are biaxial force balance inclinometers designed with an output circuit configuration made for use in 4-20 mA data transmission systems. The 4-20 mA system is used extensively in industrial installations in order to transmit data over long distances in environments where interference from nearby electrical power lines could be a problem.
A single +15 volt supply powers both the sensor and 4-20 mA line driver. Special desensitization circuitry allows these devices to provide accurate tilt data while in substantial vibration environments. Models SI-702BI and SI-702BIHP Biaxial Inclinometers are similar configurations that provide voltage output in addition to current output. Consult the factory for customized versions of these sensors.
