Measure very fast pressure transients
Dytran Instruments has announced a series of piezoelectric high-frequency pressure sensors. Model Series 2301B probe-type pressure sensors measure very fast pressure transients, such as those encountered in field blast and shock tube applications. They feature 1 microsecond rise times and acceleration compensation, plus very high natural frequency to minimize ringing induced by fast rise time inputs. The 2301B Series is being reintroduced to the testing community with a new laser welded diaphragm design. Sensors are hermetically sealed and consist of six full scale range models, from 250 psi to 15,000 psi, in a slender probe configuration. Instruments are constructed with compression-mode quartz crystals. A tiny seismic mass located within the crystal element works like an accelerometer canceling vibration effects. www.dytran.com Dytran Instruments, Inc.
