RIXEN MESSTECHNIK GMBH & CO. KG | Manufacturer of pressure gauges

Precise pressure gauges from Rixen Messtechnik in use worldwide

With over 50 years of experience in the manufacture of measuring instruments, we are able to provide you with accurate pressure gauges. The physical unit of pressure is one of the most important parameters used to monitor and control processes in process plants, laboratories and air conditioning systems. Accurate measurement of pressure is essential to the success and safety of these processes. When you use our pressure gauges, you benefit from the proven measuring principle of the ring balance.

The ringbalance for long-time accurate measurement of low pressures

ringkoerper

Our pressure gauges are equipped with a rotating ring that is almost half filled with a liquid sealing medium. The barrier fluid and a partition at the top of the ring define two chambers which can be pressurised to different pressures via valves.

A calibration weight is attached to the bottom of the ring. The higher pressure pushes the liquid towards the lower pressure. The ring rotates until the weight of the displaced liquid and the calibration weight are in equilibrium. The angle of rotation corresponds exactly to the pressure difference between the two chambers.

Transmitters convert the angle value into an electrical signal that can be used for pressure control or as a limit transmitter.

This measuring principle allows very small pressure differences to be measured accurately.

As there are no springs or diaphragms involved, which tend to fatigue or change shape over time, the accuracy of our pressure gauges is maintained over long periods of time.

Pressure gauges according to customer requirements

We manufacture pressure gauges to your individual requirements. Just tell us the type of instrument you need, the range you require and the type of power supply you require.

We can supply pressure gauges with analogue or digital display as transducers, as simple indicators or with limit contacts.
Pressure gauges with built-in three-point stepping controller.
All instruments can be used to measure differential, positive or negative pressure, depending on the connection of the pressure inputs.

For use in potentially explosive atmospheres, we can offer pressure gauges certified to the ATEX manufacturer directive 2014/34 / EU.

In order to maintain and improve the high quality of our pressure gauges, we work according to the current criteria of the ISO9001: 2015 standard and have been certified to this standard by the German Quality Management Academy GmbH.
