Vibration transducers
SPM Marine & Offshore vibration transducers deliver high-quality vibration data from rotating machinery on vessels and offshore installations. The piezo-electric accelerometers are inpidually tuned and equipped with built-in preamplifiers for accurate monitoring of motors, gearboxes, thrusters, fans, and pumps, with electrical isolation ensuring low noise in demanding shipboard environments.
Built for long service in tough marine conditions, they feature stainless or acid-proof steel housings, hermetic sealing, and strong resistance to humidity, salt, and mechanical shock. Used in Intellinova online systems or with portable instruments, SPM vibration transducers provide the reliable data needed to trend machine health and support condition-based maintenance at sea.

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.
