Meggitt's Endevco model 2271A extreme temperature piezoelectric accelerometers operate over a wide temperature range
Meggitt Sensing Systems has announced the debut of the Endevco model 2271A series, an accelerometer family designed for high-reliability vibration and acceleration measurements in cryogenic and other extreme environments.
Available with either 10-32 side connector (model 2271A) or 10-32 top connector (model 2271AM20), the Endevco model 2271A series is designed to reliably operate over a wide operating temperature range of -269° C to +260° C (-452˚ F to +500˚ F) with unusually flat temperature response. Units exhibit excellent output sensitivity and stability over time, with shock survivability to 10,000 g pk. The piezoelectric sensing elements of the model 2271A series are housed in a corrosion-resistant stainless steel case, which is hermetically sealed for use in demanding environments. Signal ground is isolated from the sensor’s outer case. A three-meter (ten-foot) low-noise coaxial cable is supplied for error-free operation. As a self-generating device, the accelerometer family requires no external power source for operation. In addition, select models are eligible for purchase under the Endevco-R replacement sensor program.
