Dynamic Pressure Calibration Systems

Overview and Selection Guide

The Modal Shop's Dynamic Pressure Calibration System offerings are based on two product lines with a rich heritage of calibration experience. The pressure actuators and measurement equipment have been in use for decades at PCB Piezotronics, while the data acquisition and automation software is based on The Modal Shop’s 9155 Series of vibration sensor calibration workstations. Each System, from Low Pressure to Ultra High Pressure, merge these two product lines to form standalone dynamic pressure calibration systems with mature measurement capabilities. The Modal Shop also offers a unique line of shock tube products for characterizing dynamic pressure sensors.

In addition, all Dynamic Pressure Systems are offered as retrofit packages to existing customer owned PCB calibration systems. TMS also offers versions that expand the 9155D Accelerometer Calibration Workstation to include dynamic pressure.

K9905C Pressure Calibration System

Ultra High Pressure Calibration System - K9905D

The K9905D provides high pressure calibration in two modes: step pressure pulses using oil media, or quasi-static pressures via brass. This ‘brass’ calibration is used with PCB 117B conformal pressure sensors for lot testing of ammunition casings.

  • Dynamic Range - 10,000 to 75,000 psi, 520 MPa, 5,171 bar
  • Available as upgrade to 9155D, and as a field upgrade of PCB Model 905C

K9901C Pressure Calibration System

Instrumented Shock Tube - 9901C

The 9901C uniquely characterizes pressure sensors using pressure waves created by diaphragm rupture. The reflected and incident pressures are measured. Formerly offered as PCB Model 901A10. The integrated system K9901C includes acquisition hardware and software.

  • Pressure Levels - from 10 psi to over 1,000 psi (20 kPa/0.2 bar to over 6.9 MPa/69 bar)
  • Helium or compressed air media
  • High frequency content allows determination of sensor resonant frequency
