Product
Hydrostatic Pressure
VEGABAR, VEGAWELL
-
The measuring cell of the pressure transducer detects minute changes in hydrostatic pressure, which increases or decreases depending on the filling level. The acting pressure is converted into an output signal by the integrated electronics.

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
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.

Radiometric Principle
-
In radiometric density measurement, an isotope emits focussed gamma rays. The detector on the opposite side of the pipeline receives the radiation.

Product
Guided Wave Radar (GWR)
VEGAFLEX
-
In level measurement with guided wave radar, microwave pulses are conducted along a cable or rod probe and reflected by the product surface. The measuring probe of the TDR sensor ensures that the signal reaches the medium undisturbed. Liquids, bulk solids and separation layers (interfaces) in liquids are commonly measured with this measuring technique.

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.

Product
Electronic Differential Pressure
Density Measurement
-
An innovative software and hardware concept makes it possible to combine any two pressure transmitters of the VEGABAR 80 series into an electronic differential pressure system to measure density. Electronic differential pressure measurement is used for measuring density change and/or for compensation when the level needs to be measured.

Product
Wireless Communication
-
The wireless communication devices are used when measured values have to be transferred from remote monitoring stations or mobile tanks to data collection centers. They also enable wireless remote diagnostics and maintenance of the connected sensors.

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
Software
-
Computer programs, algorithms, and digital logic (FPGA) used to manipulate, filter, and analyze signals after analog-to-digital conversion.
-
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
Radiation-Based
-
A non-contact, industrial process technology that uses gamma radiation to detect the boundary layer (interface) between different materials.
-
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
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
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.
