Optionally available adaptations, such as flange and ball joint versions, extend and complement the range of possible applications. Typical fields of application include: Measuring the stroke on riveting machines Measuring insertion distances Offset measurements on bearings Spring travel measurements on axes Measurements of the movement of hoisting platforms Length measurements on pipe bending machines

Due to its high resolution also when measuring long distances, linear displacement measurements up to 900 mm can be carried out. Conversions between rotatory and translation movements through ball screws, wire or cord connections and so on are not necessary for direct displacement measurement. Application fields include: —Electromagnets —Deformations - bending —Pneumatic cylinders —Length tolerances —Press-insertions (longitudinal press-fits) —Feed strokes —Machine hubs —Punch, knee lever or extruder distances —Hydraulic cylinders Due to the technology employed in potentiometric displacement sensors, they always operate with a sliding contact system. Special processes are applied to give the resistance tracks low friction, low tendency to stick/slip, resistance to abrasion and long-term stability. The rod is guided in a low-play floating frontal bearing. This absorbs small angular and parallel displacements.

The high resolution allows linear measurements to be accurately sized even in large measurement ranges. Conversion of rotatory and translational motion by spindles, wires or others is not necessary for direct displacement measurement. Areas of application are: —Hydraulic and pneumatic cylinders —Detection of positions on coordinate —Inspection machines —Displacement of plungers, knee levers or extruders —Coil and de coil lengths —Strokes on chassis —Metering strokes Displacement sensors model 8718, using a resistance track made of conductive plastic material, are suitable for direct, accurate and absolute measurements of displacements and lengths. Special processes are applied to give the resistance tracks low friction, low tendency to stick/slip, resistance to abrasion and long-term stability. The vibration-cushioned slider allows a clear signal output even by slight shocks or high operating speeds up to 10 m/s.

White light interferometers use infrared light in the non-visible range (approx. 840 nm wavelength), which means that the measurement position cannot be seen. To visualize the measuring position, Micro-Epsilon systems are equipped with a pilot laser which projects a light spot onto the measuring position. In addition, the pilot laser uses a patented method to provide feedback on the distance in addition to the measurement position. If the measuring object is at the correct distance and within the measuring range, a constant glow is emitted by the pilot laser. If the measuring object is outside the measuring range, the pilot laser flashes.

Not containing any rotating parts, it requires no maintenance if properly used. The strain-gage based sensor’s modular design allows precise configuration for the desired application. With the integrated amplifier option, the sensor directly supplies a voltage signal of 0 ... ±10 V that is proportional to the torque. The sensor can be configured via the micro-USB interface, providing access to, for example, a filter frequency setting, averaging, and a tare function.

The linear transducer model PWA measures the absolute position of the plunger without contact or wear using an inductive resonator measuring system. This consists of an excitation coil which causes an oscillating resonance circuit (moving target) fastened to the plunger to oscillate. This in turn excites the receiver coils fixed in the housing, which are printed on a printed circuit board. The integrated electronics transform these signals (sin/cos) into a signal proportionate to the linear travel. The measuring system is insensitive to electrical and magnetic fields. 0(4) to 20 mA and 0 to 10 VDC are available as standard as analogue signal outputs. CANopen, IO link and SSI are in preparation. The sensor is fastened using at least two retaining clips HK-01 or using sliding blocks ST-01. The sensor can be equipped with ball joints at the front and rear. Alternatively, the sensor's plunger can be designed as a button.
