Please note the Ex specific safety information that you can find at www.vega.com and that comes with each instrument. In hazardous areas you should take note of the appropriate regulations, conformity and type approval certificates of the sensors and power supply units. The sensors must only be operated on intrinsically safe circuits. The permissible electrical values are stated in the certificate. Take note of safety instructions for Ex applications

Measuring principle, voltage supply and measured value transmission 1 Measuring principle, voltage supply and measured value transmission Measuring principle The devices emit a continuous radar signal through their antennas. The emitted signal is reflected by the medium and received as an echo by the antenna. This is the simplest way to bring the data directly - without additional transmission facilities - worldwide into the VEGA Inventory System. The frequency difference between the emitted and received signal is proportional to the distance and depends on the filling height. The...

Instrument selection 3 Instrument selection Application area VEGAPULS Air 23, 41, 42 series radar sensors are used for autarkic, non-contact level measurement of liquids and bulk solids. They can be used in both simple and aggressive liquids. The sensors also measure light and heavy bulk solids absolutely reliably, both with strong dust and noise generation and independently of buildup or condensation. Device overview VEGAPULS Air 23 VEGAPULS Air 23 is the ideal sensor for level measurement in IBC and plastic vessels. The device measures through the closed vessel top and is suitable for...

4 Mounting Mounting position VEGAPULS Air 23 Glued connection The device version for adhesive bonding has a mounting ring with adhesive surface on the lower side of the housing. The device is for example mounted on the top of an IBC container in one of the areas shown below: Bulk solids In order to measure as much of the vessel volume as possible, the device should be aligned so that the radar signal reaches the lowest level in the vessel. In a cylindrical silo with conical outlet, the sensor is mounted anywhere from one third to one half of the vessel radius from the outside wall (see...
