High-temperature accelerometers, PiezoStar, 50 … 250 g / 8705A

Accelerometers of Type 8705A feature the unique PiezoStar seismic element from Kistler that provides both wide operating frequency and ultra-low temperature coefficient of sensitivity of 0.004%/°C. The accelerometer family operates from -55 … 165°C and exhibits low thermal sensitivity, low base strain and low transverse sensitivity minimizing measurement errors. An internal Piezotron impedance converter circuit converts the charge developed in the PiezoStar seismic element during shock or vibration into a voltage output. In addition to the ultra-low thermal sensitivity, PiezoStar accelerometers provide excellent long-term stability and repeatability.
