The IRD Model 970i is a rugged, low impedance accelerometer for use with portable instruments on all types of industrial equipment. The Model 970i incorporates the industry standard IEPE constant current interface. This is a low-output impedance, constant-current drive amplifier with a lownoise floor. The 970i design is based on the proven performance of the IRD Model 970 accelerometer. The Model 970i 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. 2 PIN CONNECTOR 10SL SENSITIVE AXIS Line Drawing:
