The Model 481-1 Piezoelectric Accelerometer is unsurpassed for general-purpose test work in adverse environments. This sensor features a BNC top connector and has been utilized extensively in the oil industry.

The internal construction of the piezoelectric seismic system ensures that this unit has no discernible spurious response to mounting torque, body strains, cable vibration, cable whip, pressure variations and most heat transients. The stainless steel housing provides an environmentally rugged unit, while the epoxy seal offers protection against industrial environments. Its grounded case construction provides tight mechanical coupling which yields accurate, wideband shock and vibration data.
