New range of compact Pressure Transmitters.
Expanded series of compact Pressure Transmitters
provide a wide, cost effective choice for industrial
measurement applications.
Druck announce a newly expanded series of Industrial Pressure
Transmitters which combine modular design with the latest advances
in ASIC technology and surface mounted electronics. This provides
a compact, lightweight and extremely competitively priced solution,
readily configured and available for a wide range of industrial pressure
measurement applications.
The expanded PTX 7500 series employs Druck's piezo-resistive silicon
technology. This has been extensively qualified and proven, for example
in aerospace and subsea programmes which demand the highest levels
of performance and long term reliability.
The PTX 7500 series features a "standardised" core which is selected
and finished according to customer requirements. It is now available
in operating pressure ranges from 100mbar up to 700 bar gauge or
absolute and user preferred pressure units and intermediate span
values can be specified between these limits.
Five types of electrical connection are available including DIN 43650
waterproof plug/socket and integral 6 pin bayonet connectors, IP65
or IP67 cable and M20 female conduit entry. A G1/4 female pressure
connection is supplied as standard with a choice of screw-in male/male
adaptors available including G1/4B, 1/4 NPT and 7/16 UNF amongst
others.
Typical accuracy is ±0.1% F.S. BSL for combined non-linearity,
hysteresis and repeatability and the operating temperature range
of -40° to 100°C is standard for connector versions. (80° max for
cable versions). The sensor is enclosed by an electron beam welded
stainless steel body and Hastelloy isolation diaphragm. This rugged
construction ensures compatibility with a wide range of pressure
media and the ability to withstand even severe operating conditions.
On-site trimming of the transmitter output is via non-interactive
potentiometers which are readily located inside the electrical connector.
The PTX 7500 series also offers excellent RFI immunity, meeting the
highest level of CE marking requirements for heavy industrial use.
ATEX Intrinsically Safe versions are also available for use with
hazardous area barrier systems.
These are certified to BAS 01ATEX 1254, EEx ia IIC T4 (T amb. 80°C).
