Cryogenic Charge

Endevco Cryogenic Charge Output Accelerometers

PCB's acquisition of Endevco's full line of testing sensors means that now all Endevco sensors are supported by PCB's comprehensive Total Customer Satisfaction (TCS) guarantee, providing enhanced confidence and reliability for customers. Endevco® cryogenic piezoelectric accelerometers are specifically engineered for precise vibration measurement under extremely challenging cryogenic conditions, operating reliably down to -452° F (-269° C). The signal outputs from these sensors remain exceptionally stable even at such extremely low temperatures, ensuring consistent performance. Their robust internal construction is carefully designed to endure multiple cycles of thermal shock, including steep and rapid temperature changes. These accelerometers are self-generating devices that require no external power source for operation and contain no active electronics. This unique design enables them to function effectively below the -320° F (-196° C) operating limit of standard ICP accelerometers, reaching temperatures as low as -452° F (-269° C) without loss of performance.
