Hydraulic Impulse Calibrator for Dynamic Pressure Sensors

Now Available as a Complete ISO 17025 Compliant System with Software

Depew, NY USA, April 15, 2009 – Model 913B02 Hydraulic Impulse Calibrator from PCB Piezotronics, Inc. provides dynamic field or laboratory calibration of piezoelectric pressure sensors. PCB® Model 913B02 is a hydraulic impulse calibrator that uses a drop mass on a piston to create half-sine pulses. The piston acts on a hydraulic fluid filled cylinder for comparison calibration of dynamic pressure sensors against a PCB® Model 136A tourmaline transfer standard. The hydraulic cylinder is fitted with the tourmaline transfer standard and has an opposing mounting port for the sensor under test (SUT). Typical performance specifications are 2-3 millisecond rise time with a pulse duration of about 5-6 milliseconds.

PCB® Model 136A transfer standard is a linear volumetric tourmaline pressure sensor designed to accurately measure rapidly changing hydraulic pressures to 20,000 psi. It is structured with a single tourmaline crystal, precisely suspended between two steel supports. Since there is no diaphragm or housing to affect the linearity of the tourmaline crystal, this sensor makes an excellent calibration transfer standard for use in impulse-type calibrations. Model 136A transfer standard may also be dead-weight calibrated periodically to verify performance.

Software and data acquisition hardware available from The Modal Shop, a PCB Group Company, allows a metrology lab to acquire the measurements with a PC controlled, high-quality instrumentation grade 24-bit dynamic signal analyzer. Data processing is automated with an easy-to-use graphical user interface that measures and displays impulse signals from the reference sensor and SUT. Calibration results are stored within an underlying Microsoft Access database, and ISO 17025 compliant calibration certificates are generated using Microsoft Excel, allowing for simple customization, if required. The entire system, including PCB® Model 913B02, 136A transfer standard, verification sensor, mounting adaptors, signal conditioning, cables, data acquisition hardware, and software installed on a system controller PC is available as a turnkey workstation Model K9913C from The Modal Shop.
