200350 and 200355 Accelerometers

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. Application Alert If housing measurements are being made for overall protection of the machine, consider the usefulness of the measurement for each application. Most common machine malfunctions ( imbalance, misalignment, etc.) originate at the rotor and cause an increase ( or at least a change) in rotor vibration. For housing measurements alone to be effective for overall machine protection, a significant amount of rotor vibration must be faithfully transmitted to the bearing housing or machine casing, or more specifically, to the mounting location of the transducer. In addition, exercise care in the physical installation of the transducer. Improper installation can result in a degradation of the transducer’ s performance and/ or the generation of signals that do not represent actual machine vibration. Upon request, we can provide engineering services to determine the suitability of housing measurements for the machine in question and/ or to provide installation. Vibrasindo.
