PCB Piezotronics launches extreme-temperature charge accelerometers

April 17, 2018

Depew, NY. PCB Piezotronics Inc., a manufacturer of vibration and pressure monitoring instrumentation, has announced the release of accelerometers designed for use in research and development programs for aviation/power-generation turbines. Models 357A64 and 357M168 are two extreme-temperature (1,200°F/649°C), single-ended-output, charge accelerometers with a UHT-12 sensing element and integral hardline cable terminating in a 10-32 jack connector.

These two models join Model 357A63 to complete an accelerometer family with three models in similarly sized housings that withstand very high temperatures, each with a different mounting option: 357A63, up to 900°F (482°C) with stud mount;357 A64, up to 1,200°F (649°C) with screw-tab mount; and 357M168, up to 1,200°F (649°C) with weld-tab mount.

The UHT-12 sensing element features proprietary crystal technology sealed in a hermetic package to provide long-term reliability. Reduced thermal noise spikes eliminate false alarms during monitoring. More consistent sensitivity over a wide temperature change provides greater accuracy. Shear-mode crystals prevent base strain and transverse measurement errors.

PCB Piezotronics, Inc. offers various charge amplifiers to support the launch of these new accelerometers, including Models 422E35 and 422E36.
