DIGI SENS AG

Measuring principle

The gravitational acceleration is measured by two silicon differential capacitors. The middle plate of each capacitor forms the seismic mass.

The suspension of the capacitor plates ensures a pure vectorial measurement, i.e. a complete separation of the tilt measurement in the X- and Y-axes. The signals are converted electronically, to give the tilt angles as a 5V TTL frequency output signal. An internal temperature measurement allows a mathematical temperature correction of both zero and gain. The BJ inclinometer covers a measuring range of ± 10% (± 5.7°) inclination from the horizontal. The resolution is 0.01°.

Signal processing

 The BJ inclinometer is designed for connection to one of the DIGI SENS processors. These are capable of mathematically compensating the weighing results from the load cells, as a function of the measured inclination.The data specific to the inclinometer are stored on a built-in memory chip. No adjustment whatsoever is required on commissioning or when replacing an inclinometer.
