Differential pressure gauge

The standard version is designed with two pointers and a gauge pressure scale. The pointer for the minus connection is connected to an additional moving dial. On the scale of the moving dial, the differential pressure (± 50 % of the main scale's full scale value) can be read directly.
Alternatively, in the version without additional moving dial, the differential pressure is not indicated.
In the version with a subtracting movement, the differential pressure is indicated with only one pointer (the individual pressures of plus and minus connection are not displayed). The variance of scale versions ensures an optimal readability of all operating parameters.
The models 731.12 and 733.02, with wetted parts from stainless steel, have been specifically designed for the requirements in the process industry. For harsh operating conditions (e.g. vibration), the instruments are also available with an optional liquid filling.

High working pressures PN 40

These differential pressure gauges are made of highly corrosion-resistant stainless steel. A high overpressure safety is achieved by the all-metal construction and the close-fitting design of the pressure measuring diaphragm. With its high-grade stainless steel construction and robust design this pressure gauge is geared to chemical and process engineering applications. It is suitable for gaseous or liquid media, also in aggressive ambience. The scale ranges of 0 ... 60 mbar to 0 ... 40 bar are available to meet the requirements of a wide variety of applications.

process industry Model

These differential pressure gauges are made of highly corrosion-resistant stainless steel and feature an all-metal, all-welded media chamber to ensure long-term leak tightness (no elastomer sealing elements).
A high overload safety is achieved by the all-metal construction and the close-fitting design of the pressure measuring diaphragm.
With its high-grade stainless steel construction and robust design this pressure gauge is geared to chemical and process engineering applications. It is suitable for gaseous or liquid media, also in aggressive ambience.
The optionally available low-temperature version allows the use for temperatures of down to -70 °C (-94 °F).
The scale ranges of 0 ... 16 mbar to 0 ... 25 bar are available to meet the requirements of a wide variety of applications.

h magnetic piston Model 700.02

The model 700.01 is primarily used for monitoring differential pressures, even at high working pressures, in the gas and air preparation and supply industry.
The model 700.02 version with separating diaphragm is for liquid media and, thus, suitable for the water treatment and supply industries.
This piston-type differential pressure measuring instrument offers particular advantages through its compact, modular design. Thus, subsequent replacement of the measuring system and the indicating case is possible on site. The reed contacts can also be retrofitted and adjusted on site.
