Meggitt Sensing Systems has announced the launch of Endevco models 6237M70 and 6237M71, two compact, extreme high temperature piezoelectric accelerometers with 10 pC/g output, designed for continuous, reliable operation in temperatures of up to +1200°F (+650°C) with long mean time between failure (MTBF).
The low-profile design of Endevco models 6237M70 and 6237M71 facilitates installation into cramped locations with minimal structural support. Model 6237M70 has its sensitive axis located in-line with the mounting screw, while model 6237M71 is perpendicular, or transverse, to the mounting screw. Both models are ground isolated, and offer a resonant frequency of 11 kHz, with frequency response to 3 kHz (±5%). As charge output piezoelectric devices, they are self-generating, and require no external power for operation. Sensing elements and integral shield are case isolated, and are contained within a hermetically healed Inconel housing. Units are supplied with a 10-foot (3.1 meter) integral hardline cable, with other lengths available upon request, and easy single-bolt mounting via a high-temperature 10-32 UNF-2B end connector and supplied 10-32 screw.
