> Bypass level indicator

The level gauge model BNA consists of a bypass chamber, which, as a communicating tube, is connected laterally to a vessel via at least 2 process connections (flanged, threaded or welded). Through this type of arrangement of the level gauge, the level in the bypass chamber corresponds to the level in the vessel. The float with a built-in permanent magnetic system, which is mounted within the bypass chamber, transmits the liquid level, contact-free, to the magnetic display mounted to the outside of the bypass chamber. In this are fitted, at 10 mm intervals, two-coloured plastic rollers or stainless steel flaps with bar magnets.

> Sight glass level indicator

For steam, the glasses can be used up to 243 °C, with mica design to 300 °C. For other media, temperatures up to 300 °C are possible, in special cases up to 374 °C. The use of mica is needed for specific applications.

> Submersible pressure sensors

The submersible pressure sensor, sometimes also referred to as a level probe, is a special type of pressure sensor for hydrostatic level measurement in tanks, wells, shafts and bore holes. For this, the submersible pressure sensor is submerged directly in the liquid to be measured, and positioned as close as possible to the bottom. There, the submersible pressure sensor measures the hydrostatic pressure, which enables a direct conclusion regarding the current level, i.e. the height of the liquid column above it.

> Continuous measurement with float

Our level sensors enable the continuous measurement of levels, independent of physical and chemical changes of the media such as foaming, conductivity, dielectric, pressure, vacuum, temperature, vapours, condensation, bubble formation, boiling effects and density change. Via the HART® interface, parallel measurement of interface layer and overall level is possible. The level can be displayed proportional to height or volume. Process connection, guide tube and float can be manufactured from stainless steel 1.4571, 1.4435, 1.4539, titanium or various plastics.

> Float switches

Float switches are used for the point-based limit level detection of one or several levels. They work independently of foaming, conductivity, dielectric, pressure, vacuum, temperature, vapours, condensation, bubble formation, boiling effects and vibrations and are suitable for almost all liquid media. The switching operation is contact-free, free from wear and needs no power supply. The simple and proven functional principle of the float switches enables a very wide range of applications, from general industrial applications through to use in process plants.

> Optoelectronic switches

Optoelectronic switches are used for the detection of limit levels in liquids. The detection is widely independent of physical characteristics of the liquids such as density, dielectric constant, conductivity and refractive index.

These instruments are notable for their compact design and do not feature any moving components. With a measuring tip from borosilicate or quartz glass, and robust stainless steel cases, they offer a high media compatibility.
