New flush diaphragm Pressure Transmitter.
The new LPX7000 is extremely rugged with oil-free abrasion
resistant flush diaphragm design ideal for hostile/viscous
media applications such as process slurry and sludge
monitoring.
GE Druck, a unit of the General Electric Company (NYSE: GE) and
a leading provider of precision pressure sensors and related
test/calibration instruments, announced today a new series of high
performance rangeable Flush Diaphragm Pressure Transmitters.
The GE LPX 7000 series is ideal for use in hostile conditions, where
conventional devices cannot accurately or reliably perform with
abrasive process media and cleaning processes, pressure shock,
condensation and other severe environmental conditions. Typical
applications include pressure monitoring in sludge, tar, coal slurry,
food processing and tank level monitoring of liquids and beverages,
chemicals, residues, cement and pulp/paper processes.
Performance of the GE LPX7000 Transmitter is assured by the
combination of an innovative oil-free, low displacement inductive
pressure element and rugged yet highly adaptable packaging.
The heat treated Inconel X750 diaphragm requires no isolation fluid
and moves typically just 0.2mm, enhancing long term mechanical
reliability. It is thicker than conventional flush diaphragm devices,
which also ensures a substantially longer life when used in abrasive
processes. A long neck design allows the flush diaphragm to be
located remotely from the electronics, allowing service at process
temperatures up to 250 deg C as standard and even 450 deg C by
can be accommodated using a custom version.
The GE LPX7000 also provides customers with a flexible asset
management solution when planning sensor requirements. It allows
4:1 user rangeability on standard ranges from 50mbar/20 in H20
to 35bar/500psi with a wide choice of pressure units. The 2 wire
4-20mA output can be set bi-directional eg to cover negative
pressure/vacuum up to the positive range value required and the
4mA zero can also be elevated (eg 4-20 mA reps 1.5 to 10 bar)
for tare value/offset process measurements.
For ease of installation and maintenance, the wide choice of industry
standard process connections includes Tri-ClampÒ, DIN and
VariventÒ, PMC M44, 2" BSPT with welding nipple/plug and saddle
mount options. The LPX 7000 also operates from a standard 2 wire
loop supply between 12 - 30Vdc and a choice of two electrical
connections is provided as standard. The DIN A connector version
is sealed/weatherproof to IP65, whilst the 1/2NPT conduit entry
version is supplied with integral cable and IP67rated. Product weight
is from just 900 grams dependant on mechanical configuration.
