Kistler pressure sensors for ATEX zoned hazardous environments
The range of high performance, pressure sensors from Kistler Instruments (www.kistler.com) are now available certified for use in ATEX Zone 0, intrinsically safe and Zone 2, non-incendive hazardous areas.
The sensors use a new, patented double lip sealing method which eliminates the need for an O-ring seal ensuring accuracy and reliability where extremely high temperature, vibration and shock are likely. Contained in a high integrity housing, the piezoresistive sensing element is isolated from the pressure media by a welded 316L stainless steel or HastelloyTM diaphragm. Integrated surface mount electronics provide signal conditioning and temperature compensation.
The three ranges consist of absolute (Type 4260A), gauge (Type 4262A) and differential (4264A) pressure sensors all 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 both pressure and temperature ranges to ensure compliance with the appropriate specification. This calibration data, traceable to ISO 17025, is available for all versions.
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.
The ATEX certified piezoresistive pressure sensors have been designed to withstand harsh operating conditions where extremes of temperature, vibration and shock are likely to be present. Typical applications include R&D, industrial, automotive and aerospace component and system testing and a wide range of electrical and pressure connections are available.
