PCB Piezotronics Model 907A Shockless Pressure Step Generator

Description

PCB Piezotronics Model 907A Shockless Pressure Step Generator: a specialized calibration tool used primarily to test the dynamic response of pressure sensors. Key Details Function: It generates a fast, "shockless" pressure step to measure the rise time and frequency response of piezoelectric pressure transducers. Mechanism: It typically uses a poppet valve mechanism (labeled "Poppet Pressure Adjust" at the base) to quickly expose a sensor to a regulated reference pressure. Application: Used in laboratories to ensure high-frequency sensors can accurately capture rapid pressure changes, such as those found in blast or combustion testing. Manufacturer: PCB Piezotronics, based in Depew, NY. Unit features a large blue cylindrical housing with a viewing cutout, and various adjustment knobs at the base for controlling the internal pressure and poppet release.
