The WIKA 712.15.160 and 732.15.160 Differential pressure gauges are characterised by their compact and robust design and are primarily used for level measurement on liquid gas tanks. With only six 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. Versions with transmitters can be expanded with the Remote data transfer module intelliMETRY. The intelliMETRY sends measured data to an online data centre using GSM technology. 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.

The WIKA 712.15.100 and 732.15.100 differential pressure gauge high-quality gauges are characterised by their compact and robust design and are primarily used for level measurement on liquid gas tanks. With 11 different measuring cells, all common 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 efficiently. An optional valve manifold for flange mounting with working pressure indication makes the central measurement of both level and operating 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.

The WIKA 332.50 / 333.50 high-quality test gauge has designed for the measurement of pressures with high accuracy. With its accuracy class of 0.6, the 33x.50bourdon tube pressure gauge is suitable for testing industrial type pressure gauges or for precision measurement in laboratories. Optionally, an accuracy class of 0.25 is available for pressures ‰¤ 400 bar. For the respective measuring requirement, a scale range between 0 … 0.6 and 0 … 1,600 bar can be selected. The optimal readability of the instrument, with a nominal size of 160 mm, is achieved via a knife-edge pointer and a dial with fine divisions. Supported through the optional mirror band scale, the parallax error can be eliminated. The wear-resistant precision movement, the wetted parts and the case are made from high-grade stainless steel. The instrument meets the requirements of the international industry standard EN 837-1 for Bourdon tube pressure gauges and has a blow-out device with a blow-out plug on the back of the case. In the event of a failure, overpressure can escape there and the operator is protected at the front side. For harsh operating conditions (e.g. vibrations), the instruments are also available with an optional liquid filling.
