Applications
■ Level measurements 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 … 80 mbar to 0 ... 1725 mbar
■ High working pressure (static pressure) of 50 bar
■ Overpressure safety either side up to 50 bar
■ 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.
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.
Design and operating principle
Pressures p1 and p2 act on the media chambers ⊕ and ?, which are separated by an elastic diaphragm (1).
The differential pressure (Δp = p1 - p2) leads to an axial deflection of the diaphragm against the measuring range spring (2).
The deflection, which is proportional to the differential pressure, is transmitted to the movement (5) in the indicating case (4) via a pressure-tight and low friction lever mechanism (3).
Overpressure safety is provided by metal bolsters (6) resting against the elastic diaphragm.
