New extreme high temperature accelerometers enable more accurate measurements

IRVINE, Calif., USA – June 26, 2018 – Meggitt Sensing Systems, a division of Meggitt PLC, has released the Endevco Model 6243M family — the latest in our range of extreme high temperature piezoelectric accelerometers. This new design is immune to pyrospiking, also known as thermal velocity spiking, ensuring more accurate measurements particularly in applications where there are rapid changes in temperature.

The 6243 can operate continuously at +1200°F (+650°C) which is an important feature in turbine and engine testing for aircraft, power generation, agricultural, and other large industrial applications.

Key features include:
– 1200˚F (650˚C) continuous operation, +1400˚F (+760˚C) intermittent operation
– Integral hardline cable to customer specified length
– Hermetically sealed
– No pyroelectric or thermal velocity spiking
– Single-ended and balanced differential output options

Four variations exist within the family to allow for use in a variety of different test set ups. The 6243 model is Meggitt’s first high temperature accelerometer to offer a balanced differential output. Customers can select two signal outputs; single-ended or balanced differential; and two mountings (sensitive axis parallel or perpendicular to the mounting bolt).
