A manufacturer of electrical equipment has expanded its line of inclinometers with the Q42, a dual-axis sensor with a CANopen interface. This makes the sensor ideal for use on mobile equipment and off-road vehicles.
A MEMS (micro-electro-mechanical system) device at the heart of the Turck Q42 inclinometer uses a micro-electromechanical capacitive element. The sensor uses two parallel-plate electrodes, one stationary and one attached to a spring-mass system. Movement causes acceleration that produces deflection in the non-stationary electrode. This results in a measurable change in capacitance between the two plates that is proportional to the angle of deflection. All measured values and parameters are accessible by the object directory. A micro board in the MEMS device allows for a compact, precise inclinometer in a durable package.
