Accelerometer for extreme temperatures
2271A/2271AM20, -269 to +260°C Meggitt Sensing Systems - Measurement Group

The Endevco® model 2271A series from Meggitt Sensing Systems is an accelerometer family designed for high-reliability 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 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 requires no external power source for operation.

Recommended accessories include the model 2950 triaxial mounting block; signal conditioner models 133, 2775 or 4990a (Oasis); or the model 2771C in-line charge converter. The model 2271A series is ideal for use in cryogenic testing; HALT/HASS/ESS; flight test engine monitoring; environmental testing; and space hardware evaluations.
