Probes (spring-loaded sensors)

Probes are usually employed when displacement of moving or frequently changing targets shall be measured. It is practical or possible to fix the core of a standard sensor to the target. The probe tip is slightly pressed against the target, with the probe rod being guided and spring-loaded.

We offer a range of standard probes and extremely rugged types for harsh industrial applications or even pressure-resistant (<300 bar) versions.
