The Columbia Models SI-701AI and SI-701AIHP are 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. Both configurations are also available with a convenient 6-pin electrical interface. Refer to Columbia Models SI-701AIC and SI-701AIHPC. Models SI-701BI and SI-701BIHP Inclinometers are similar configurations that provide voltage output in addition to current output. Consult the factory for customized versions of these sensors.
