Highly dynamic pressure sensor with 500kHz natural frequency
19 March 2018
The new 1,000 bar, miniature Type 603C piezoelectric (PE) pressure sensor from Kistler has a high natural frequency of 500kHz which makes it suited to a wide range of applications where highly dynamic pressure transients need to be measured.
One characteristic of the 603C PE sensor is its ability to measure small pressure fluctuations, superimposed on a high static pressure, with high resolution. The integrated acceleration compensation ensures reliable measurements even under highly vibrating conditions. Add long life reliability and calibration at 10 and 100 percent of FSO making the sensor easily matched to changing needs resulting in low cost of ownership.
With linearity typically better than ±0.4 percent FSO and operating temperature from -196 to +200°C, the new sensor is 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 long 37.8mm and the short 15mm long overall versions both with a 6.3mm 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.
