Product
Flow
-
In flow measurement, the amount of material that flows through a certain pipe cross section per time unit is measured.

Product
Overvoltage Protection Instruments
-
Safety devices designed to protect sensitive electrical equipment from voltage spikes, surges, or sustained excessive voltage.

Level Measurement
-
In continuous level measurement, the level of a medium in a tank or silo is detected with the help of different measuring methods and converted into an electronic signal. The level signal is either displayed directly on site or incorporated into a process control or management system.

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
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
Ultrasonic
VEGASON
-
In non-contact ultrasonic level measurement, the sensor emits ultrasonic pulses in the direction of the medium, which then reflects them back.

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.

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
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
Vibration
VEGASWING, VEGAVIB, VEGAWAVE
-
In point level measurement with vibrating level switches, a rod or a fork is set vibrating. When the vibrating probe comes into contact with the medium, the vibration changes and the vibrating level switch outputs a switching command. Vibrating level switches are used as overfill protection devices or low-level indicators in liquids as well as in granular and powdery bulk solids.
-
Product
Signal conditioning
-
Simple parameterization of the sensors and visualization of the measured values via the on-site display.
-
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
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.
