- Construction machinery and equipment
- Railway monitoring
- Mobile satellite positioning
- Agricultural machinery and equipment
Linear and Operating Range Behavior
Certifications and Ratings
RoHS Compliant
When using an excitation circuit not designed by The Fredericks Company, ensure that no direct current passes through the sensor. Direct current will lead to sensor damage, output drift, and general instability. For a description of hardware and software design for this sensor, see application note AN1000.
The 0717-4313-99 and all sensors in the TrueTilt™ series must be mounted horizontally (parallel to the surface of the earth and perpendicular to the force of gravity). For best performance, isolate the sensor from vibrations when mounting it.
