Single-axis accelerometer 970

piezoelectricruggedwaterproof

The IRD Model 970 is a rugged, low impedance accelerometer for use with portable instruments on all types of rotating machinery. The Model 970 has built-in electronics to provide a low impedance output and eliminate the need for special low noise cables. The Model 970 is sealed against dust and moisture and operates up to a temperature of 250°F (121°C). A single ¼” - 28 mounting stud is used for attaching the accelerometer to a flat surface. Insulated mounting adapters are available for those cases where ground potential problems may exist between the transducer mounting surface and the instrument. Operating power and current for the accelerometer are supplied externally, typically from the instrument.
