Accelerometers and pressure sensors for use on combustion turbines require special consideration during design and manufacturing processes. Typical applications for high temperature sensors include condition monitoring of power generation turbines, gas turbine bearing health monitoring and turbine/compressor sets in oil & gas pipelines.

This white paper illustrates how resonant frequency of an accelerometer is determined via Hooke’s Law and the spring-mass harmonic isolator. It also explores the concepts of mass and mounting methodology stiffness, the two main factors that affect the resonant frequency (and therefore high frequency response) of an accelerometer.
