OMEGA’s DPX101 dynamic pressure transducers are ideal for measuring pressure transients or dynamic pressure pulsations in liquids or gases. With their wide dynamic range, they can measure pressure events with rise times as fast as 1 µs, frequencies to hundreds of kHz, and pressure levels down to fractions of a psi. Using pure synthetic quartz crystals under high compressive preload, these transducers produce a clean, low-impedance voltage signal compatible with many readout instruments.
