Pressure sensors perform under transient pressure

The range maintained in stock for fast delivery is the general purpose high frequency 113 series comprising eight models with pressure measurement capabilities ranging 50-15,000psi and sensitivity ranging from 0.5-100mV/psi. Seven of the 113 series are ICP sensors requiring no signal conditioning with model 113B03 offering charge output for the highest measuring range to 15,000psi and sensitivity of 0.39pC/psi (±15%). All 113 series sensors feature 10-32 coaxial jack connectors for ease of set up.

Based on piezoelectric crystal technology, PCB’s pressure sensors are suitable for measuring dynamic pressure changes being able to detect the smallest of pressure fluctuations even in the presence of high static pressures. This makes them useful for transient measurements due to their high frequency responses and fast rise times. Applications include detection of pressure fluctuations in fuel lines and pipelines and cavitation from ship propellers. Dynamic pressure sensors can also be used in loud acoustic applications, for example, when measuring close to a F1 car as microphones are limited to a maximum of 174dB. Model 106B features a range of 8.3psi which is equivalent to 189dB and the company has other models that can exceed these levels.

For applications in fracking, PCB offers a range of safe pressure sensors compatible with the long cables typically encountered in such environments. Additional applications include air blast and underwater explosion measurements, peak and total impulse, explosives research and structural loading, shock tube or closed bomb testing, wave velocity and/or time of arrival determinations and explosive testing.

Model 105C02 is a subminiature ICP pressure sensor offering measurement range of 100psi with 50mV/psi sensitivity. This tiny sensor features a 17-42.5mm diameter diaphragm and is suitable for use in space restricted applications.

PCB Piezotronics’ range of pressure sensors is backed by the company’s guarantee of Total Customer Satisfaction (TCS) and supported with a range of accessories including mounting adaptors to ensure best practice for a quality installation and avoidance of time consuming errors.
