Meggitt Introduces High-Temperature Piezoelectric Charge Output Accelerometer

Meggitt Sensing Systems announced the global market introduction of the Endevco model 2280, a hermetically sealed, triaxial, piezoelectric charge output accelerometer with high-temperature operation to +482 degrees C (+900 degrees F).

According to the company, the model 2280 is suited for vibration measurements across three orthogonal axes on aircraft engines, aerospace components, ground-based turbine engines, power plant equipment and other machinery that operates at high temperatures.

It shares the same piezoelectric charge sensor system as the company’s single-axis 2248 family. Offered with a sensitivity of 3 pC/g, it features Meggitt’s proprietary piezoelectric elements and Isobase construction, to provide mechanical isolation of the sensing assembly from the mounting surface and minimize base strain.

The accelerometer is 1.35 inch (35mm) square and weighs less than 0.6 pounds (270 grams). It has three 10-32 side connectors and is mounted with two 8-32 bolts. The unit is hermetically sealed, and signal ground is isolated from the outer case of the unit. Three 10-foot Endevco model 3075M6-120 high-temperature, low-noise cables are supplied with the unit along with two mounting screws.
