Accelerometer, Top Exit Applications • Light Industrial • Gear Boxes • Motors • Roll & Process Equipment • Pumps Features • Two-wire, Current Driven • Hermetically Sealed • Electrically Isolated • Single-Point Mounting • Integral Cable Option Description The 4-160-1001 basic top exit accelerometer is intended to satisfy the general requirements for a low cost vibration transducer for use in multipoint experimental or light industrial vibration monitoring applications. The two-wire current loop operating principle permits very long interconnecting cables to be used where necessary and at minimum expense since standard screened pair (or multi-pair) cables may be used. The piezoelectric sensor and amplifier are contained within an inner metal enclosure which is electrically and thermally insulated from the outer stainless steel body. This arrangement prevents ground loops and minimizes the effects of thermal shocks and base strain. The inner enclosure is connected to the 0V of the two-wire system and is therefore an effective electrical screen. External connections are made via a top exit integral cable or electrical connector. The transducer is mounted by means of a single threaded hole in the base of the cylindrical body, this being intended to accept a mounting stud of the standard (non-insulating) type.
