Product
Microwave Barrier (Radar)
-
The microwave barrier functions like a light barrier: when the medium gets in the way of the microwave beam between the transmitter and the receiver, the signal is attenuated. This change is detected by the receiver and converted into a switching signal.
-
Product
Software
-
Computer programs, algorithms, and digital logic (FPGA) used to manipulate, filter, and analyze signals after analog-to-digital conversion.
-
Product
Signal conditioning
-
Simple parameterization of the sensors and visualization of the measured values via the on-site display.
-
Product
Radiation-Based
PROTRAC
-
Radiometric point level detection operates with a radioactive source that emits focussed gamma radiation. The radiation is picked up by a detector on the opposite side of the vessel. When the gamma rays are blocked by the medium, the detector receives little or no radiation. The intensity changes of the incoming radiation are forwarded as signals by a relay.

Product
Conductive
VEGAKON, EL
-
When the electrodes of the conductive point level sensor come into contact with a conductive fluid, a small alternating current begins to flow.
-
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
Controllers
-
Sensors gather measured values in a vessel and forward them to the controller. Through an adjustment in the controller, the measured values can be adapted to the specific conditions at the measuring point.

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.
-
Product
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
Differential Pressure
-
In differential pressure measurement, different pressures act on an oil-filled, pressure difference measuring cell from two sides. The instrument converts the pressure differential into an electronic signal.

Product
Separating Instruments
-
Separators separate intrinsically safe from non-intrinsically safe circuits. Distinguishing features are the type of power supply and the size of Ex-specific characteristics.

Product
Differential Pressure (Density)
VEGADIF
-
In density measurement of liquids with differential pressure, two pressure measuring points are mounted at a fixed distance from each other. There are thus two different pressures acting on the system. The differential pressure transducer calculates the density of the medium from the resulting pressure difference.
-
Product
Radiation-Based
-
A non-contact, industrial process technology that uses gamma radiation to detect the boundary layer (interface) between different materials.
-
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.
