Meggitt Sensing Systems has 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).
With its small package, the model 2280 is ideally 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.
The Endevco model 2280 shares the same piezoelectric charge sensor system as the companys popular single-axis 2248 family with 15 years of field-proven performance. Offered with a sensitivity of 3 pC/g, the model 2280 features Meggitts proprietary piezoelectric elements and patented 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 for error-free operation along with two mounting screws. Recommended optional accessories include the Endevco model 2721B charge amplifier and 2771C remote charge converter. The sensor is fully compliant with the European Union Low Voltage Directive 2006/95/#C and EMC Directive 2004/108/EC and bears the CE mark.
All sensing elements are manufactured in-house at Meggitts ISO9001-certified MEMS facility in Sunnyvale, California, USA. In addition, the Endevco model 2280 is covered by a five-year comprehensive product warranty.
