In continuous level measurement, the level of a medium in a tank or silo is detected and converted into an electronic signal. The level signal is either displayed directly on-site or incorporated into a process control or management system. The measured media are liquids, pastes, powders, or bulk solids.

Typical applications for continuous level measurement are process tanks, storage tanks, or silos in the process industries.

In point level detection, a point level switch detects when a certain predefined level is reached. Such a device is employed when it is not necessary to measure every possible intermediate level, as is the case with continuous level measurement. A switching command starts or stops filling equipment such as conveyors or pumps. Point level switches outputting a binary signal can be integrated into a process control system. Point level detection systems can be used in liquids, pastes, powders, or coarse bulk solids.

Typical applications for point level detection are process tanks, storage tanks, silos, and pipelines in the process industry. Point level detection is used for minimum or maximum detection, leak detection, or overfill protection.

Pressure Measurement

Pressure measuring techniques can be used to measure not only process or differential pressure, but also level, volume, or mass in all areas of process technology. The measured media are commonly gases, vapors, and liquids.

The measuring ranges of pressure transmitters start at a few psi and go up to several thousand psi. Different measuring cells are used for pressure detection.

The proportion of solid matter in a liquid is determined with the help of density measurement.

Typical industries that benefit from radiation-based density are mining, power generation, petroleum supply, and pulp and paper. Radiation-based density provides lasting performance due to its non-contact measurement principle.

ReSource Program®

The ReSource Program® offers a responsible method of source end of life management as an alternative to stockpiling and burial. Through a rigorous testing and amendment process, old sources are certified as new. This dramatically reduces radioactive waste.

Signal Processing

Industrial processes are highly automated. To ensure smooth operation, measuring instruments are employed to deliver a steady flow of up-to-date, objective information about the process to the control and regulation technology. Various hardware components as well as signal conditioning software process and integrate the measurement data. They convert the analog or digital signals from the measuring instruments into information that are displayed on indicating instruments or fed directly into the control system.
