The 200350 and 200355 Accelerometers are general purpose, casemounted seismic transducers designed for use with Trendmaster Pro Constant Current Direct Input Card 149811-02 and the Seismic Direct Input Card 164746-01. These transducers can also be used with a number of other Bently Nevada products, including 1900 Series, ADAPT.wind, 3500 Series, Snapshot IS and Snapshot CE.
The 200350 and 200355 Accelerometers are contained within a hermetically sealed, stainless steel case. The design provides an extremely rugged transducer, well suited for harsh industrial environments. Each transducer’s top mounted, 2-pin connector (MIL-C-5015) allows for easy installation and removal of the interconnecting signal cable. A ¼-28 threaded hole on the bottom of the casing accommodates multiple mounting options.The 200350 and 200355 Accelerometers contain a piezoelectric sensing device, which generates charge when subjected to vibration.
This charge is then converted electronically to a differential voltage signal, which is proportional to the acceleration that is parallel to the sensitive axis of the transducer.
