Highly dynamic pressure sensor with 500kHz natural frequency

The company's new 1000 bar, miniature Type 603C piezoelectric (PE) pressure sensor has a very high natural frequency of 500kHz 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. In addition, 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.

With linearity typically better than ±0.4% FSO and operating temperature from -196 to +200°C, the new sensor is said to be big in performance but small in size. A 5.5mm diameter, robust, high pressure membrane is mounted in a hermetically sealed, welded, stainless steel housing available in both 37.8mm and 15mm long versions, both with a 6.3mm overall diameter.

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