Pressure Sensor Calibration System
The Modal Shop offers specialized calibration systems for dynamic pressure sensors, which are typically calibrated by modifying the amplitude of the input signal. Our solutions cater to a broad spectrum of pressure measurement applications, including atmospheric blast experiments, gas turbine exhaust fluctuations, internal combustion engine measurements, ammunition brass calibrations, and hydraulic or fuel line measurements. Leveraging the expertise and metrology heritage of PCB Piezotronics, our systems have been rigorously tested and validated through tens of thousands of factory calibrations. Our cutting-edge digital hardware and software platform ensures precise and reliable calibration, meeting the exacting demands of industrial and research applications.

Low Level Dynamic Pressure Sensor Calibration
Our system provides low-pressure transient inputs to the sensor under test, in accordance with ANSI B88.1 standards. It offers a pressure range of 5 to 150 psi, or 1 MPa, allowing for precise calibration of sensors.Â
Mid-Level Dynamic Pressure Sensor Calibration
Our system provides low-pressure transient inputs to the sensor under test, in accordance with ANSI B88.1 standards. It offers a pressure range of 5 to 150 psi, or 1 MPa, allowing for precise calibration of sensors.
High Level Dynamic Pressure Sensor Calibration
Our high-level dynamic pressure sensor calibration system provides accurate calibration using impulse input, with a wide pressure range of 100 to 15,000 psi (103.4 MPa) for high-pressure sensor testing.
Ultra-High Level Dynamic Pressure Sensor Calibration
Our ultra-high level dynamic pressure sensor calibration systems offer extreme pressure calibration up to 80,000 psi (550 MPa) for specialized applications like ammunition brass and oil testing.
High Frequency Instrumented Shock Tube
Our High Frequency Instrumented Shock Tube (K9901C) is a unique system that tests pressure sensors by generating shock waves through diaphragm rupture. The system measures incident and reflected pressures, delay time, and ambient conditions, with pressure levels reaching up to 1,000 psi (6.9 MPa).
