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.
