Extreme-temperature charge accelerometers.

Models 357A64 and 357M168 are two extreme-temperature (1,200[degrees]F/649[degrees]C), single-ended-output, charge accelerometers with a UHT-12 sensing element and integral hardline cable terminating in a 10-32 jack connector. They are designed for use in research and development programs for aviation/power-generation turbines.

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[degrees]F (482[degrees]C) with stud mount; 357 A64, up to 1,200[degrees]F (649[degrees]C) with screw-tab mount; and 357-M168, up to 1,200[degrees]F (649[degrees]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.

The vendor offers various charge amplifiers to support the launch of these new accelerometers. PCB Piezotronics Inc., www.rsleads.com/806ee-177
