The probe tip of these sensors is pushed onto the measuring object by a spring. This makes it possible to use these sensors were a mechanical modification of the measurement object (mounting hole) is not allowed or difficult. Output voltage as function of the displacement with the impedance as parameter. Sensors of series 87350 generally consist of an oscillator, a demodulator and a transformer with moveable core. They are energized by DC voltage. The oscillator uses this DC voltage to generate the carrier frequency, which is needed for the operation of the sensor. Dependent on the position of the core, which is made of ferromagnetic material, voltages are induced by the two secondary coils of the transformer.

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.

he greatest challenge in the use of inductive displacement transducers is the optimization of linearity. Usual linearity deviations are around 0.30 % of the measuring range of the sensors. Values that are significantly below this can hardly be realized. With the help of the LVDT digital controller from eddylab, to which either one or two sensors can be connected, the linearity deviation of inductive displacement transducers can be almost completely eliminated. KeyFeatures ■ Improves linearity up to 0.01%. ■ High resolution (16 bit) ■ High dynamic range ■ Digital output CAN, USB interface ■ Analog output ■ High noise immunity

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.
