The rugged construction and fully sealed body enables this transducer to be used in most Industrial environments. The main body of the transducer is fitted with a polished stainless steel case and contains a moving coil and magnet assembly. The coil is suspended within the field of the magnet by means of diaphragms which permit virtually frictionless movement in one axis only. This measuring axis is coincident with the axis of the cylindrical body. The devices are simple to interface with monitoring equipment, being passive, and the high sensitivity in conjunction with low noise makes them particularly suitable for power generation applications where the grounding and electrical interference environment is always a challenge. The limited upper frequency response (typically 2kHz) also assists in steam turbine applications where high frequency steam noise can saturate active devices leading to spurious alarms.
