New Pressure Transmitters are lightweight & cost effective.
Druck announce a new series of pressure transmitters
which combine modular design with the latest advances
in ASIC technology and surface mounted electronics.
This provides a lightweight and cost effective alternative
to the traditional pressure gauges and switches.
The new PTX 7800 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 7800 series features a "standardised" core which is available
in operating pressure ranges from 70mbar up to 700 bar gauge or
100mbar up to 700 bar absolute, with proportional 2 wire 4-20mA output.
User preferred pressure units and intermediate span values can be
specified between these limits and compound (bi-directional gauge)
ranges can be supplied.
To simplify the replacement of pressure gauges and switches, the
PTX 7800 series is available with a G ½ male threaded pressure
connection. Alternatives include G¼ female, G½ male to BS EN387-1
(DIN 16288) and ½ NPT male.
For ease of electrical connection, a standard M20 male conduit entry
is supplied with integral cable. Accuracy is +/- 0.25% F.S. for combined
non-linearity, hysteresis and repeatability and the operating temperature
range of -40 to 100°C ambient is standard. 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
The PTX 7800 series also offers excellent RFI immunity, meeting the
highest level of CE marking requirements for heavy industrial use.
ATEX intrinsically safe and flameproof versions are also available
for use within certified hazardous areas.
