Linear Accelerometers SA 107AI

The Columbia Models SA-107AI and SA-107AIHP Force Balance Accelerometers are 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.

The Model SA-107AI is a low cost device, while the SA-107AIHP incorporates Columbia's patented HP torquer design providing improved accuracy and repeatability in adverse shock environments. Models SA-107BI and SA-107BIHP are similar configurations that provide voltage output in addition to current output. Consult the factory for customized versions of these sensors.
