Vibration transducers

The transducers are piezo-electric accelerometers of compression type; each individually tuned, with built-in pre­amplifier, designed for vibration monitoring of industrial machinery. The electrical signal is isolated from the transducer housing. Enhanced electronics and improved ambient characteristics deliver excellent performance in a very large area of applications.

The transducers are designed to withstand the rigors of industrial environments. Stainless, acid-proof steel housings, case isolation, and hermetic sealing make them very robust.

Technical overview

Our vibration transducers come in a variety of sizes, configurations, and specifications to perfectly suit your needs. All transducers are internally isolated. The frequency range is specified for the transducer when permanently installed. The measuring results will be affected at higher frequencies when using a magnetic foot.

Installation materials

Connectors, cables, and service box

We offer a wide range of connectors in composite or stainless-steel material. Composite material provides benefits such as vibration dampening and weight reduction, while stainless steel can withstand mechanical forces and works both in high and low temperatures, etc.

For our connectors, there are different types of cables, and to further secure the installation, we supply uncovered, acid-proof stainless steel conduits. These are protective covers slipped onto the cable and fixed to the transducer at the connector. Stainless steel cable clips are available for holding the conduit. For the protection of cable joints from moisture and water, a stainless, acid-proof steel service box is available.

Contact your SPM representative to learn more and discuss your needs.
