Liquid-based inclination sensors
The BSI inclination sensors from Balluff offer an enclosure rating of IP67 and are designed where inclination angles need precise detection.
The new, liquid-based BSI inclination sensors from Balluff detect deviations on an axis over a full 360° contact-free. They offer accuracy of 0.1°C, a resolution of 0.01° and a temperature drift of just 0.01%/10K. They are designed for situations where inclination angles need to be precisely detected or rotary movements must be constantly tracked.
BSI inclination sensors feature a compact and robust metal housing with an enclosure rating of IP 67 and can be easily installed in systems with limited space. With an expanded temperature range of -40C to + 85C, the sensors are virtually predestined for outdoor applications.
Balluff BSI 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 is scaled linearly over the angular range of 360 deg.
