Genspec GS4200
®
General Purpose Pressure Transmitter
Technical Data
The GENSPEC GS4200 pressure transmitter is
designed to meet the operational requirements of
demanding pressure measurement applications
where good quality, fast delivery and low cost are of
the highest priority.
The unique Silicon-on-Sapphire sensor technology provides
outstanding performance and gives excellent stability over
a wide temperature range. The advanced sensor design
consists of a piezoresistive silicon strain gauge circuit, which is
epitaxially grown onto the surface of a sapphire diaphragm to
form a single crystalline structure. The sapphire sensor element
is then molecularly bonded to a titanium alloy sub-diaphragm.
This enables the sensor to endure higher over- pressures and
provides superb corrosion resistance. The sensor exhibits
virtually no hysteresis and excellent long-term stability. With
outstanding insulation properties, the sapphire substrate allows
the sensor to operate over a very wide temperature range
without loss of performance.
Dimensions
(in mm)
Standard accuracy is ±0.25% with an over pressure limit of
twice the rated pressure range, this together with easy access
for re-calibration afrm the excellent design. All models
are supplied with integral 1/4” BSP or alternative pressure
connections. Optional higher accuracy, outputs and electrical
connections are available. The all titanium alloy wetted parts
offer unbeatable corrosion resistance. Versions are also
available offering IP66 sealing for installations requiring high
levels of environmental protection. Applications for the GS4200
include the continuous monitoring of hydraulic systems with
oil, gas, water and other process liquids, industrial, medical
and aerospace industries. Also ideal for the measurement and
control of pressure in refrigeration, pneumatic, compressor,
HVAC and engine monitoring systems.
An optional ATEX and IECEx approved version of this product
is available for explosion protection for ammable gases (zone
0), dusts (zone 20) and mining areas (group I M1).
DNV GL rules for classication of ships, high speed & light craft
