Micropulse transducers for reliable position measurement

International certifications

Many applications require the use of transducers in explosive atmospheres. Pressure-encapsulated magnetostrictive transducers are available in different rod designs and with varying performance profiles for use in Ex-zones 0 and 1. There are variants for use in areas where there is a risk relating to gas or dust as well as a transducer for Ex-zone 2 that can withstand the potentially explosive conditions there.

Pressure-encapsulated housing

The housing is robust and pressure-encapsulated, and the electronics module can be changed quickly and easily. This means that every transducer variant for the Ex-zone meets the requirements set by the oil and gas industries for high reliability and simple service.
