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.
