Inclinometers – Solutions for many applications

No matter if applied in harvesters, agricultural and construction machinery, in vehicles and airplanes or in machines, robots and solar plants: Sensors for measuring and monitoring inclination are universally applicable and help to improve the safety and efficiency of operations.

Inclination is defi ned as the relative angular tilt to the horizon or perpendicular. Inclinometers use the local gravity respectively acceleration of gravity as a reference to measure angular tilt. The measuring principle is similar to that of perpendicular drop, whereby the mass is directly related to the gravitational field. Following this principle, inclinometers use mechanical pendulums, bending beams or liquids like in water-levels.

TURCK inclinometers incorporate a micromechanical pendulum based on MEMS technology (Mikro Elektro Mechanic Systems). The core piece is a capacitive sensor element consisting of two parallely arranged plate electrodes with a dielectric in the middle.

The dielectric of this differential capacitor is designed as a resilient pendulum. If the position of the sensor changes, the dielectric in the middle moves, causing the capacitance ratio between both electrodes to change. This change in capacitance is exactly measured and processed to detect the angular tilt.

The extremely rugged TURCK inclinometers are also suited for fast production sequences and withstand impacts. The standard product portfolio comprises rectangular shaped, biaxially operating inclinometers Q20L60, with angular ranges of ±10°, ±45° and ±60°. It also includes devices with analog voltage, current or ratiometric output as well as 20 mm uniaxial versions with freely adjustable measuring range 0° … 360° and analog or digital output.

The Q42 complementing the product range, features a standard CANopen interface (CiA DS-301). These sensors provide baud rates of 10 kbps up to 1Mbps, high sampling rates and bandwidths as well as parameterizable vibrostability.
