Overview POSITAPE®

POSITAPE® position sensors utilize the functional principle of the POSIWIRE® position sensors. Instead of using a cable, POSIWIRE® position sensors are constructed with a specially designed stainless steel tape. This high-tech robust stainless steel tape has a nearly unlimited life cycle. Thus, POSITAPE® position sensors are perfectly suited in applications that require pulleys due to the tight locations where the sensor must be installed. The rugged design is shock and vibration resistant and makes POSITAPE® position sensors suitable for use in harsh environmental conditions.

Advantages at a glance:

  • Nearly unlimited life cycle of the measuring tape
  • Extremely robust against dirt
  • Narrow axial design
  • Low wear
  • High linearity due to electronic linearization (up to 0.05%)
  • Measurement ranges up to 20,000 mm
  • Integrated dust wiper

Applications

Due to the robust stainless steel tape POSITAPE® position sensors are perfectly suited for pulley applications, as well as for use in hostile environments, e.g. in the sector of mobile working machines. POSITAPE® position sensors can also be used in applications in which the absence of particles is required due to hygienic regulations, like in the food processing industry or pharmaceutical industry.

The functional principle

The POSITAPE® sensor operates by attaching the measurement tape from the sensor directly to the moving object. The measurement tape is coiled onto a cable drum that is under constant spring tension. The unwinding process from the drum converts the linear movement of the measuring tape into an angular movement which is then captured using angle sensor elements (encoders or potentiometers) and converted into an electrical output signal. Subsequent signal conditioners convert the signal of the sensing element into voltage (0,5 ...10 V), current, (4...20 mA), or digital pulses (SSI) suitable for standard interfaces.
