Balluff BSI inclination sensors

The liquid-based BSI inclination sensors from Balluff detect deviations to the horizontal on an axis over a full 360°, contact free, with a high accuracy of 0.1°, a resolution of 0.01° and a temperature drift of 0.01%/10 K.

The inclination sensors feature a compact and robust metal housing with an enclosure rating of IP67 and can be easily installed in systems with limited space. With an expanded temperature range of -40 to + 85°C, the sensors can be used in outdoor applications.

The inclination sensors are based on a capacitive measuring principle and are equipped with a liquid-based measuring cell. These consist of four capacitors filled with a liquid dielectric. Depending on the inclination of the sensor, the ‘horizon’ of this medium covers the capacitors differently, causing the capacitance - as measure for the inclination angle - to change. The analog output signal from 4-20 mA analog output signal is scaled linearly over the angular range of 360°C.
