Differential pressure gauge
Cu-alloy or stainless steel version
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)
- Option: Remote data transfer module intelliMETRY
- Option: 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.

Bourdon Tube Brass Gauge
Industrial Series Liquid Filled
Applications for Bourdon tube brass gauges:
- Intended for adverse service conditions where pulsation or vibration exists
- Suitable for gaseous or liquid media that will not obstruct the pressure
- Hydraulics and compressors
Special features of Bourdon tube brass gauges:
- Vibration and shock resistant
- Solid forged-brass case and socket
- Pressure ranges up to 15,000 psi (1,000 bar)
Specifications of Bourdon tube brass gauges:
With a solid forged-brass case and socket, WIKA's Bourdon tube brass gauge is designed for the most adverse conditions, including high vibration.
In fact, this brass gauge (model 213.40) is also known as WIKA's "hydraulic gauge." It is commonly used in mobile and stationary machinery hydraulic applications because of its ability to withstand extreme vibration, shock and pulsation.
