2.1
With the wire principle, a linear motion is transformed
into a change in resistance by a rotation.
A measuring wire made of highly flexible stainless steel
wires is wound onto a drum with the aid of a long life
spring motor.
The winding drum is coupled axially with a
- multi-turn potentiometer (Type WDS - ... - Pxx- ... -
P/U/I) respectively with an
- encoder (Type WDS - ... - Pxx - ... - E/A).
2.2
The draw wire principle is used in the housing
design P60 / P96 / P115 with different measuring
lengths from 100 to 15,000 mm (3.93 to 591 in).
Five versions of the electrical connection are possible
- Potentiometer output (resistance divider)
- Voltage output (with integrated electronics)
- Current output (with integrated electronics)
- Incremental encoder (with integrated electronics,
output: HTL- or TTL-level)
- Absolute encoder (with integrated electronics)
