Meggitt Sensing Systems has
introduced the Endevco model 2273A series, a family of radiation-hardened
piezoelectric accelerometers for vibration measurements within nuclear and
power generation environments.
Offered with a high sensitivity of 10 pC/g, the Endevco model 2273A series
is available in both top (model 2273AM20) and side connector (model 2273AM1)
versions. Both are radiation hardened for exposures to gamma flux up to 6.2 x
1010 and integrated neutron flux up to 3.7 x 1018 N/cm2.
The accelerometers incorporate the use of Meggitt's crystals in its Isobase
construction, providing for flat temperature response over a range of -184 C to
+399, and operation at frequencies of up to 6000 Hz. Sensing elements are
housed in a rugged stainless steel package, which is hermetically sealed. This construction
further allows for mechanical isolation of bending motion from the mounting
base and low base strain sensitivity, for a transducer series that can continue
to operate within extreme environments with up to 10,000 g pk shock
survivability.
