Accelerometer works in 760°C environments

Accelerometer works in 760°C environments

The Endevco model 6240M10, a hermetically sealed piezoelectric charge-output accelerometer, can operate continuously at temperatures up to 649°C and intermittently to 760°C. The transducer’s ability to perform at extreme temperatures suits it for monitoring aircraft and ground gas-turbine vibration, exhaust and compression systems, and other high-temperature equipment.

With a sensitivity of 5 pC/g, the 1.335 x 0.80 x 0.80-in. sensor is stable over a wide operating bandwidth as well as temperature, and is compact enough to fit in tight spaces. The ground-isolated unit’s sensitive axis is in line with its supplied mounting bolt (a transverse version is optional), and sensing elements and integral shield are also isolated from its case. Operation requires a charge amplifier or remote charge converter that accepts a 100-kΩ source, but no external power is needed. (Contact Bruce Lent for pricing, availability.)
