Mini capteurnumérique Metro

Miniature digital gauging probe

Ideal for measurement in confined places


In a world where everything has became digital, the digital probe brings important improvements with regards to the existing technologies. The digital probe consists of the probe itself and of its electronic head.

The digital probes have the same dimensions as the conventional probes and can be installed with similar mounting arrangements.

The electronic head houses the circuits that encures the digital conversion of the signal as well as the communication management with the M-bus network. A "T" connector allows the probes juxtaposition.

The digital probes are equipped with a M-bus network interface compatible with our display units.


The mini probe is a compact low profile transducer that is ideal for measurements in confined places such as bores. The transducer is based on a parallel spring structure that ensures that it provides excellent repeatability over a long working life, even when rotated in bores that have key slots or lubrication ports.
