Endevco 2273AM1 Highlights
Endevco® piezoelectric accelerometer models 2273AM1 and 2273AM20 are specially designed for use in nuclearreactor- vibration and loose-parts-monitoring systems. The 2273AM1 and 2273AM20 are differentiated only by the location of their connectors, the AM1 being side mounted and the AM20 utilizing a top-mount configuration. The accelerometer is a self-generating device that requires no external power source for operation.
The 2273AM1 feature Endevco's Piezite® Type P-14 sensing elements in our patented Isobase® construction, providing a flat temperature response over the range of -65°F to +750°F (-55°C to +400°C). Their Isobase® construction provides mechanical isolation of the seismic system from the mounting base, resulting in very low strain sensitivity. The case is made of Inconel and provides for hermeticity through welding and glass-tometal fusion at the connector.
