Applications
Level measurement in closed tanks, particularly in
cryotechnology
Filter monitoring
Monitoring and control of pumps
For gaseous and liquid media that are not highly viscous or
crystallising and have no suspended solids
Special Features
Differential pressure measuring ranges from 0 ... 40 mbar to
0 ... 4000 mbar
High working pressure (static pressure) up to 50 bar
Overpressure safety either side up to 50 bar
Scaleable measuring ranges (maximum Turn Down of 1 : 3.5)
Very compact design
Optionally compact valve manifold with working pressure
indication
Description
These high-quality gauges are characterised by their compact
and robust design and are primarily used for level measurement on liquid gas
tanks.
With only 6 different measuring cells all usual tank sizes
in cryotechnology are covered. As a result of the large measuring range overlap
of the respective measuring cells, the gauge installed on the tank can be
adjusted to match a whole variety of gases such as Ar, O2, N2 or CO2, with a
full-scale deflection over a complete 270 degree sweep. The span adjustment is
accessible from outside and does not affect the zero point. The mechanical
display and the optional electrical output signal are calibrated simultaneously
and easily.
An optional valve manifold for flange mounting with working
pressure indication makes the central measurement of both level and working
pressure possible in the one instrument.
The level display can be supplied with an optional,
integrated 4 … 20 mA, 2-wire transmitter. Switch contacts for level and working
pressure, as well as a transmitter for the working pressure can be retrofitted
on site.
The standard centre distance of 37 mm between the process
connections can be adapted to a custom centre distance of 31 mm or 54 mm using
adapters for flange mounting.
