The Series HEVP Piezoelectric Accelerometers are precision manufactured biaxial probe sensors designed for vibration measurements in two mutually perpendicular axes. Complete vibration studies may be performed over the entire length of a tube by simply moving the probe within the tube. 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.
The accelerometers and all connecting leads are completely waterproof and designed to withstand water pressure and temperature variations. It's small size and unique mounting configuration accommodates tubes and pipes with internal diameters as small as 0.60 inches. The Series HEVP accelerometers are equipped with an integral sheathed cable that can be ordered in any length up to 150 feet long. Consult the factory for customized versions of these sensors.
