Accelerometer designed for 482°C operation.
Endevco's Model 2248/2248M1 is a small piezoelectric
accelerometer designed for shock and vibration
measurement of structures subjected to very high
The accelerometer is capable of operation in nuclear environments
during the presence of gamma and neutron radiation, and features
a side 10-32 receptacle with either flange (2248) or integral stud-mount
(2248M1). Featuring Endevco's PIEZITE® Type P-14 sensing element
in patented ISOBASE® construction, the Model 2248 provides flat
charge temperature response over the range of -55°C to +482°C
(-67°F to +900°F). ISOBASE construction offers mechanical isolation
of base strain from the mounting surface.
The Model 2248 is a self-generating device that requires no external
power source for operation. Constructed using Inconel, the accelerometer
is hermetically sealed by welding and glass-to-metal fusion at the
connector. Signal ground is connected to case. Endevco Signal
Conditioner Model 2721B is recommended for use with this
accelerometer. The 2771B Remote Charge Convertor is also
compatible for applications using the Model 2248/2248M1.
Endevco has a factory-direct sales force in the U.S. and is represented
in the rest of the world by Brüel & Kjær. Brüel & Kjær has offices in 55
countries and 7 accredited calibration centers worldwide. Endevco is
a subsidiary of U.K.-based Meggitt PLC, an international group of
companies renowned for their specialized engineering skills.
