Ultrasonic Level Transmitters

The OPTISOUND line offers affordable ultrasonic level transmitters that can measure levels in basins, containers, and tanks without contact. OPTISOUND also lends itself to being used in the inlet of the system where the flow in open channels can be determined indirectly via the height.

Company team

Contract Level Transmitter

The Optiflex line of products is guided radar level meters. They are easy to set up and a cost-effective solution for continuous level measurement of liquids and solids.

Company team

Radar Level Transmitters

The OPTIWAVE line offers level transmitters for liquids in basic process applications. It’s specially designed for continuous, non-contact level measurement. These transmitters provide accurate readings even in processes with fast changing levels, in closed tanks or in the open air. They can be used in hazardous areas and come with extensive device diagnostics.

Pressure Measurement

OPTIBAR range of pressure transmitters is high-performance pressure transmitters that can be tailored to a wide variety of industrial process applications.

Company team

Pressure Transmitters

The OPTIBAR series offers process pressure, hydrostatic pressure, and differential pressure applications for complete measuring points for flow, level, or process pressure applications. These include pressure transmitters with ceramic or metallic measuring cells, differential pressure transmitter with integrated absolute pressure measurement, and high overload resistance.

Company team

Diaphragm Seals

The OPTIBAR diagram seals are used for pressure, density and level measurement, especially for high process temperatures of up to 400 °C/752 °F, for corrosive media, or in conjunction with different hygienic and pharmaceutical process connections.
