Pressure sensors for tough tasks

Kistler Instruments has launched a range of small, high performance differential pressure sensors for use in harsh test environments where temperature extremes, high vibration and shock levels are present.

The design of the Type 4264A sensor is based upon proven Kistler piezoresistive sensing technology. A silicon sensing element is mounted within a high integrity seal assembly that is isolated from the pressure media by a welded 316L stainless steel or Hastelloy diaphragm.

Integrated surface mount electronics condition the output from the silicon sensing element and provide temperature compensation.

Additional electronic circuit boards can be added to configure the electrical output for a wide choice of voltage and mA outputs. As a result, the sensor can be factory configured to provide an electrical output to suit a variety of data acquisition systems. Noninteractive zero and span calibration adjustments can be provided.

A special sealing method enables the sensor to withstand multiple cycles without fatigue. The design also enables flexibility in choice of pressure connections without use of adaptors or 'O' rings.

The sensors come in uni-directional and bi-directional types with pressure ranges from 0.1 to 10 bar differential, all with 300% proof pressure. ATEX versions are available.
