The displacement transducers operate according to the principle of run time measurement between two points of a magnetostrictive waveguide. One point is determined by a moveable position magnet, whose distance from the null point corresponds to the section to be measured. The run time of an emitted impulse is directly proportionate to this section. Conversion to an analogue measuring signal takes place in the downstream electronics. The waveguide is housed in a pressure-resistant stainless steel tube or extruded profile. To the rear of this is a die-cast aluminium housing containing the electronics in SMD technology. Electrical connection is implemented via a circular connector. In the rod version, the position magnet is located in a ring, which is guided over the rod without contact. In the profile version, it is located either in a slider, which is linked to the moving part of the machine via a ball joint, or it moves as a liftable position magnet, without wear, over the profile.

The sensor system is intended as a component for use e.g. in wind power plants to measure and evaluate vibrations in the mast head. Registration of dynamic accelerations by means of MEMS sensors (Micro-Electro-Mechanical System) with subsequent digitisation by a controller.The device consists of an acceleration sensor, a controller unit and the output interface PROFIsafe over PROFINET for output of the acceleration values. Thanks to its high resistance to vibration and shock - more than the defined measuring range -, the sensor is suitable for use in areas with rough environmental conditions.Electrical connection is carried out using three connectors.

Registration of inclination in the gravitation field using MEMS sensors (Micro-Electro-Mechanical-System) with subsequent digitisation and linearisation via a controller. Data output is carried out via the CANopen interface or as an analogue signal. The inclination sensor has a stable aluminium housing (optionally stainless steel). Slots are available for mechanical alignment (up to approx. ± 7.5°). In the case of CANopen, one connector or one male/female connector combination can be selected optionally for connection purposes. Casting measures in the housing lead to the achievement of protection class IP 69K, e.g. for use under water.

Registration of inclination in the gravitational field by means of MEMS sensors (Micro-Electro-Mechanical-System) with subsequent digitisation and linearisation via controllers. The housing-based inclinometer (model NBN 65) has a stable aluminium housing (optionally stainless steel) and is highly-resistant to vibration and shock. One or two connectors/socket in the case of CANopen can optionally be selected for connection. Casting measures in the housing lead to the achievement of protection class IP 69K, e.g. for use under water.

The displacement transducers operate according to the principle of the differential choke, i.e. an inductive half bridge. They consist of two coils which are encapsulated in a stainless steel cylinder ensuring positive protection against vibration, shock, humidity, oil and corrosive matter. A mu-metal plunger core causes opposing changes of inductance when it is displaced through the centre of the coils. The displacement transducers are designed for a carrier frequency of 10 kHz. Other frequencies can be used but may involve changes of output values.

The displacement transducers work according to the principle of the differential choke (inductive half bridges). They consist of two coils which are encapsulated in a Mu metal cylinder in a sealed and vibration-proof manner. A Mu-metal plunger causes an opposite induction change in the two coils when displaced by the hollow coil body. The displacement transducers are designed for an oscillator frequency of 10 kHz. Power supply and signal conditioning are provided by external module modules.
