Inductive linear motion sensors TWK-ELEKTRONIK IT 108 series they have a non-contact sensor system. Magnetization and signal processing are carried out by external electronic modules. The design of these sensors includes two symmetrical spirals for measurements, which are located in a metal cylinder, inside which there is also a rod that moves longitudinally during operation. During operation, the bridge is magnetized using a 10 kHz carrier frequency generator. When the piston is displaced relative to the center, a signal appears proportional to the pulse of change during displacement. The separate electronics supplied with these sensors allow you to adjust the zero points.
Technical characteristics of TWK-ELEKTRONIK series IT 108 inductive linear displacement sensors:
- Linearity: from 0.5 % to 0.25 %;
- Measurement moves: from 2 to 4 mm;
- Operating temperature range: -20° to + 80°C.
