Three new ranges of pressure sensors from Kistler Instruments use a double-lip sealing method to eliminate the need for an O-ring seal, ensuring accuracy and reliability under conditions of high temperature, vibration and shock. Contained in a high integrity housing, the piezoresistive sensing element is isolated from the pressure media by a welded 316L stainless steel or Hastelloy diaphragm. Integrated surface mount electronics provide signal conditioning and temperature compensation.
The three ranges comprise absolute (Type 4260A), gauge (Type 4262A) and differential (4264A) with an accuracy of up to 0.05% FS and long-term stability of 0.1% FS per year. Every sensor is fully tested over pressure and temperature ranges to ensure compliance with the appropriate specification. This calibration data, traceable to ISO 17025, is available.
A wide range of electrical and pressure connections are available and ATEX zoned hazardous area types can be supplied to order. Pressure ranges from 1 to 350 barA for the 4260A, 0 to 35 barG for the 4262A and 0.1 to 10 barD for the uni-directional 4264A and ±0.1 to ±1 barD for the bi-directional 4264D. All have EMC, reverse polarity, power supply regulation and short circuit protection as standard and display exceptional linearity, hysteresis and repeatability characteristics.
