Product
Components
-
Electronic devices and circuits that manipulate, transform, and refine sensor signals to make them suitable for measurement, recording, or control systems.
-
Product
Signal conditioning
-
Simple parameterization of the sensors and visualization of the measured values via the on-site display.

Level Switches
-
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.

Product
Capacitive
VEGACAL
-
In capacitive level measurement, the sensor and the vessel form the two electrodes of a capacitor. Any change in level causes a capacitance change, which is in turn converted into a level signal.

Product
Process Pressure
VEGABAR
-
Pressure transmitters measure the pressure of liquids, gases and vapours in pipes or closed vessels. The pressure of the measured medium acts on a pressure measuring cell, which converts it into an electronic signal.The process pressure transmitters are ideal for detecting the relative or absolute pressure in applications with condensation or rapid temperature changes.

Magnetic Level Indicator
VEGAMAG
-
A safe, durable, and non-invasive instrument used to measure liquid levels in tanks or pressurized vessels.
-
Product
Guided Wave Radar
-
A top-down, direct sensing technology that uses low-energy microwave pulses sent down a probe to accurately detect the boundary between two immiscible liquids.

Capacitive Level Switches
VEGACAP, VEGAPOINT
-
In capacitive point level detection, the sensor and vessel form the two electrodes of a capacitor. Any capacitance change caused by a level change is converted into a switching signal. Thanks to the shortenable cable and rod versions, level switches can be perfectly adapted to any application. They are often used for overfill or dry run protection as well as oil/water or foam detection.

Product
Radiation-Based
-
A non-contact, industrial process technology that uses gamma radiation to detect the boundary layer (interface) between different materials.
-
Product
Hydrostatic
VEGABAR, VEGAWELL, VEGADIF
-
In hydrostatic level measurement, the measuring cell of the pressure transmitter detects even the slightest changes in hydrostatic pressure, which increases or decreases depending on the filling level. The acting pressure is converted into an electrical signal by the integrated electronics and then outputted as an output signal. Different types of measuring cells are used in level measurement based on the hydrostatic principle.

Product
Indicating Instruments
-
In continuous level measurement, the filling height in a vessel is repeatedly detected. The measured value is further processed, e.g. as a 4 … 20 mA signal in a PLC or process control system. Indication of the measured value directly on site is also frequently requested.

Radiometric Measuring Principle
WEIGHTRAC
-
In radiometric measurement, an isotope emits focussed gamma rays. The sensor on the opposite side of the conveyor belt receives the radiation.
-
Product
Pressure
-
Pressure transmitters measure process pressures as well as the levels of liquids, gases and vapours.

Product
Radiation-Based
PROTRAC
-
In radiometric, i.e. radiation-based, level measurement, a slightly radioactive isotope emits focused gamma rays.The sensor, which is mounted on the opposite side of the vessel, receives this radiation. Since gamma rays are attenuated when penetrating matter, the sensor can calculate level, point level, density or mass flow from the intensity of the incoming radiation.

Interface Measurement
-
Interfaces, that is, boundaries between separation layers, can be found everywhere in the process industry, e.g. in the chemical or oil & gas industry. An interface arises when two media with different densities are filled into a container: for example, water and oil. To separate the two media from one another, it is necessary to determine where the transition from one medium to the other is located. VEGA sensors can be used to measure both the total level and the interface reliably.
