Inclination Sensors


Inclination sensors

(QG series)

The QG series of inclination sensors measures angles in 1 or 2 axes. These products are based on robust MEMS technology, in which capacitance differences can be converted into an analogue voltage within a micro-mechanical sensor chip. This analogue voltage is proportional to the angle to which the sensor is exposed. The modular design makes it easy to adapt the sensors to specific requirements.

An inclination sensor is used in situations where accurate positioning or constant monitoring of the angle in relation to gravitational pull is essential. An inclination sensor measures the angle with respect to a horizontal position, whereby an imaginary line from the centre of the earth serves as a reference. An inclination sensor has a very wide range of applications since it can be mounted anywhere and offers flexibility in mechanical design. The sensor output has two components: a static (slope) component and a dynamic (acceleration) component. The sensor output is always a combination of these two components. The inclination sensors from DIS have a standard bandwidth of 10 Hz, although it is possible to reduce this bandwidth further at the client’s request.

The Inclination Sensor Housing

Many of the DIS sensors in the QG range use a unique universal plastic housing concept, known as QUADRO®. The advantage is the very compact size, simple installation and the fact that the electronics are fully sealed which provides a high degree of ingress protection (IP67). The housing is also available in metal (aluminum and stainless steel).
