Model 357B61 accelerometer, from the Vibration Division of PCB Piezotronics Inc., is said to offer the ability to conduct vibration measurements on high temperature objects or in high temperature environments. Claiming an ability to operate to 900°F (482°C), the unit is thought to be well suited for vibration testing and studies on engines, exhaust systems, manifolds, turbines, turbochargers, and steam handling equipment.

The unit is structured using a shear mode, piezoceramic sensing element within a hermetically sealed, Inconel housing. This is reported to provide an environmentally rugged device with resistance to oxidation, corrosion, and ability to survive 5,000 g shocks. Additional features claimed include exceptional linearity through a 3,000 g measurement range, low sensitivity deviation over the entire temperature range, and a virtually non-existent sensitivity to base strain. Included with the device is a 10 ft (3 m) hardline cable, which also survives high temperatures.
