Low-temperature IEPE accelerometers, PiezoStar, high sensitivity / 8712B

Utilizing the exclusive PiezoStar element and K-Shear design from Kistler, the 8712B accelerometers exhibit very low sensitivity to base strain, thermal changes and transverse acceleration. The unique PiezoStar sensing elements afford the ultimate in long-term stability, which ensures repeatable and accurate measurements for many years. In addition to the PiezoStar shear elements contained within the housing, a Piezotron micro-electronic circuit converts the high impedance charge signal emanating from a pair of elements into a voltage signal. The low impedance voltage output minimizes noise pick-up and eliminates the need for highly insulated low noise cables. This low temperature variant using a specific Piezotron allows sensor usage down to cryogenic temparatures of -196°C (-320°F).
