Dynamic pressure sensor

The new 1,000 bar, miniature Type 603C piezoelectric (PE) pressure sensor has a very high natural frequency of 500 kHz which makes it suited to a wide range of applications where highly dynamic pressure transients need to be measured.

The 603C PE sensor can measure small pressure fluctuations, superimposed on a high static pressure, with exceptional resolution. The integrated acceleration compensation ensures reliable measurements even under highly vibrating conditions. Long life reliability and calibration at 10% and 100% of FSO make the sensor easily matched to changing needs resulting in low cost of ownership.

Linearity is typically better than ±0.4% FSO and operating temperature from -196°C to +200°C. A 5.5mm diameter, robust, high pressure membrane is mounted in a hermetically sealed, welded, stainless steel housing available in both long 37.8 mm and the short 15 mm long overall versions both with a 6.3 mm overall diameter.

The new Type 603C PE pressure sensor has been designed for use with the recently introduced dual-mode LabAmp Type 5165A series for dynamic pressure and the Type 5167A series for both dynamic and quasi-static pressure measurements.
