Designed by Kistler, Type 6215 incorporates a quartz-crystal sensing element and front sealed diaphragm, packaged together within a rugged, stainless steel housing. This technology allows for low mechanical and thermal stresses upon the sensor, with no mounting gap (small dead volume) and a largely reduced surface pressure within the sealing part. Offered with a measurement range from 0 to 6,000 bar, the sensor features a high-impedance output and sensitivity of -1.4 pC/bar with a natural frequency of >240kHz. Units are rugged to 25,000g shock, with a 1µs rise time and ±1% FSO linearity specification across all pressure ranges. Depending upon desired measurement configuration, they may also be installed with a separately sold optional protective shield or diaphragm protection. In particular, thermal shields or plates further reduce the potential for thermal shock errors and diaphragm protection provides resistance to mechanical damage from metal fragments and powder particles. Sensor mounting is achieved via a M10x1 threaded hole. The pressure sensor meets the rigorous application demands of internal ballistics, closed bomb testing, weapons discharge, and cartridge chamber testing as well as other extreme high-pressure measurement requirements.
