Triaxial accelerometer has improved in-band signal fidelity

23 January 2012

Variohm EuroSensor has added a new triaxial accelerometer to its vibration sensor range that has improved in-band signal fidelity and a 50% increase in dynamic range over previously available models. The new 993B-7-M12, from Variohm's distribution partner, Meggitt Wilcoxon Research Inc., has a rugged hermetically sealed design that is suitable for general purpose preventative maintenance use on motors, pumps compressors and other critical rotating equipment.

With its robust M12 connector and easily replaced cable assemblies, the 993B-7-M12 equally suited to permanent mount or field portable hand-held use.

The 993B-7-M12 offers simultaneous 3-axis monitoring with 100 mV/g sensitivity over a 60 g peak acceleration range, with frequency response to 10 kHz in Z and to 7 kHz in X and Y. The low noise accelerometer design includes built-in IEPE amplifiers to minimise out of band signal influence and includes EMI/RFI shielded electronics as well as reverse wiring protection.

The 993B-M12 features a hermetically sealed 316L stainless steel case with captive screw mounting that allows full 360 degrees rotation for cable exit at any angle. The M12 connector permits a wide choice of connector options including BNC, Turck, 11-pin Fischer and 4-pin Bendix – and others on request.

Variohm EuroSensor supplies and supports a wide range of single-axis and triaxial accelerometers and velocity sensors from Meggitt Wilcoxon Research including extreme environment types and dual output sensors which measure both vibration and temperature.
