Special Application Piezoelectric Accelerometers 378
The Models 378 and 378-HT Piezoelectric Accelerometers are designed for prolonged use in adverse industrial environments of shock, vibration, temperature, humidity and excessive oil. The high charge sensitivity of 1,000 pC/g and high mounted resonance of 10K Hz provide a wide dynamic range from 0.00001 to 500 g's. Their rugged construction ensures long life and high performance stability and repeatability. The unique design of the piezoelectric seismic system ensures that the units have no discernible spurious response to mounting torque, body strains, cable vibration, cable whip, pressure variations and most heat transients. Internal electrical isolation minimizes ground loop problems from noise currents. The Models 378 and 378-HT accelerometers are equipped with a 3-pin top mounted output connector and a -28 removable stud for mounting. The Model 378-HT is designed to operate in environments up to +500 Deg. F. Features Vibration Monitoring & Process Controls High Sensitivity (1,000 pC/g) Electrically Isolated 3-Pin Connector
