New from Kulite
is a range of miniature ruggedised pressure transducers, offering
high performance and low temperature stability.
Introduced as the IS family of pressure transducers, they are intended
for cryogenic operation over the temperature range - 195.5ºC
to +120ºC. A number of ranges are available, to suit applications
with different requirements in terms of size, ruggedness or high
frequency response, for example.
The CT-375 and CT-190 Series devices, for example, are ruggedised;
and with a threaded interface, they are ideal for use in cryogenic
wind tunnels. They offer extremely good low-temperature stability
and repeatability, while also providing a high frequency response.
The CCQ-093 and CCQ-062 Series, having a 9.5mm cylindrical sensor
of 2.4mm or 1.7mm diameter, respectively, may be incorporated in
userdesigned probes.
Suitable for pressure measurements in all non-conductive, non-corrosive
liquids or gases, the devices can be used in a number of operational
modes including: absolute, gauge, sealed gauge and differential.

Device specifications include an over-pressure figure of 2 times
rated pressure, with no change in calibration, and a burst pressure
figure of 3 times rated pressure.
All of these sensor ranges provide a full scale output (FSO) of
100mV (nominal) with a residual unbalance of ±5mV. They offer
combined non-linearity, hysteresis and repeatability figures of
±0.1% FSO BFSL (typical) and ±0.5% FSO (max). The
sensors provide resolution accurate to an infinitesimal level.
Their outstanding performance stems from
the use of proprietary monolithic sensor technology. These dielectrically-isolated,
silicon-on-silicon sensors comprise three layers of silicon, which
are bonded together atomically. A layer of monocrystalline, Ntype
silicon is micromachined to create a force-summing diaphragm; a
further, P-type layer contains four strain gauges, connected together
in a Wheatstone bridge circuit; and these two layers are separated
by a silicon dioxide dielectric.
