Meggitt Sensing Systems Launches New Endevco Extreme Temperature Piezoelectric Accelerometers

Meggitt Sensing Systems, a Meggitt group division, has announced the global market 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 very 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.

Recommended accessories for the Endevco model 2271A series include the model 2950 triaxial mounting block; signal conditioner models 133, 2775 or 4990a (Oasis); or the model 2771C in-line charge converter.  With its rugged construction and precision accuracy over an extremely wide operating temperature range, the model 2271A series is ideal for use in cryogenic testing; HALT/HASS/ESS; flight test engine monitoring; environmental testing; and space hardware evaluations.  For detailed technical specifications, drawings or additional information, visit www.meggittsensingsystems.com.
