Highly accurate position measurement:

The HySense PO 100 works on the measuring wire principle. It can be easily mounted and does not need linear guiding. It is suitable for use at load cranes, hydraulic presses and other installations where distances need to be measured or changes of position detected. All mechanical and electronic components are protected by a solid casing.

The measuring wire principle:

A specially manufactured and calibrated wire is tightly wound around a high-precision drum that is driven against the pulled direction by a spring motor. Through the detection of the winding process the sensor converts the linear movement into an electrical signal.

Major advantages:

The sensor is compact, has a very high resolution and accuracy. It has a high dynamic and is insensitive to environmental infl uences.

Please consider when using the PO 180:

The exit angle of the wire from casing must be 90°, or there may be friction between the measuring wire and the casing, causing wear and tear. The top of the sensor should be protected against dirt and splash water and the measuring wire should not be positioned next to a machine or device part. The wire should never be loosened suddenly to avoid retraction into the casing.
