The liquid-based BSI inclination sensors from Balluff detect deviations to the horizontal on an axis over a full 360° contact-free and absolutely. With an extremely high accuracy of 0.1°C, a resolution of 0.01° and a temperature drift of just 0.01% /10K, they are suited for complex applications, in which 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 -40 to 85°C, the sensors are virtually predestined for outdoor applications.
The highly precise, high-end sensors show their true strength, howev-er, where deviations from the horizontal or to the vertical axis are to be determined with high resolution and accuracy: e.g., in wind power stations, in solar-thermal power plants, oil and gas production plants and in medical technology, for example, in computer tomography and irradiation facilities.
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 4-20mA is scaled linearly over the angular range of 360°C.
