Product description 1 Product description VEGAPULS series 40 sensors are a newly developed generation of extremely compact, small radar sensors for accurate, high-resolution measurement. They are characterised by very good focussing properties for applications in narrow spaces. With very modest space requirements, they were developed for measuring distances of 0 … 4 m/10 m/ 20 m and are the right choice for standard applications such as storage vessels, reservoirs and buffer tanks as well as process tanks.
Product description VEGAPULS can achieve this through a special time transformation procedure which spreads out the more than 3.6 million echo images per second in a slow-motion picture, then freezes and processes them. % 50 40 % 40 30 25 % 20 10 5% 5 0 2 0 t t Time transformation Hence, it is possible for the radar sensors to process the slow-motion pictures of the sensor environment precisely and in detail in cycles of 0.5 to 1 second without using timeconsuming frequency analysis (e.g.
Product description 1.2 Application features 1.3 Adjustment Applications • level measurement of any liquid • measurement also in vacuum • all slightly conductive materials and all substances with a dielectric constant > 2.0 can be measured • measuring range 0 … 10 m (type 42). measuring range 0 … 20 m (type 44). measuring range 0 … 4 m (type 45). Every measurement set-up is unique. For that reason, every radar sensor needs some basic information on the application and the environment, e.g.
Product description The PC can be connected at any measuring site in the system or directly to the signal cable. It is connected by means of the twowire PC interface converter VEGACONNECT 3 to the sensor or the signal cable. The adjustment and parameter data can be saved with the adjustment software on the PC and can be protected by passwords. On request, the adjustments can be quickly transferred to other sensors. Adjustment with the adjustment module MINICOM With the small (3.2 cm x 6.
Product description, types and versions Adjustment with the HART® handheld 2 Types and versions Series 40 sensors with 4 … 20 mA output signal can also be adjusted with the HART ® handheld. A special DDD (Data Device Description) is not necessary - the sensors can be adjusted with the HART® standard menus of the handheld. 2.1 Survey HART Communicator VEGAPULS 42 sensors are distinguished by a G 1½ A or 1½“ NPT threaded mounting boss as process connection.
Types and versions Survey General features • Application preferably for liquids in storage tanks and process vessels with increased accuracy requirement. • Measuring range 0 … 4 m, 0 … 10 m or 0 … 20 m. • Ex approved in Zone 1 (IEC) or Zone 1 (ATEX) classification mark EEx ia [ia] IIC T6. • Integrated measured value display.
Types and versions 2.2 Antennas The antenna is the eye of the radar sensor. The shape of the antenna, however, doesn’t give a casual observer the slightest clue on how carefully the antenna geometry must be adapted to the physical properties of electromagnetic waves. The geometrical form determines focal properties and sensitivity - the same way it determines the sensitivity of a unidirectional microphone.
Types and versions Pipe antennas Pipe antennas consisting of horn antenna and standpipe or bypass tube Only in conjunction with a measuring tube, i.e. with a surge or bypass tube (which can also be curved), do horn antennas form a complete antenna system. The measuring tube acts as a conductor for the radar signals. The running time of the radar signals changes in the tube and depends on the tube diameter.
Mounting and installation 3 Mounting and installation 3.1 General installation instructions Measuring range The reference plane for the measuring range of the sensor is the lower edge of the flange or the seal shoulder of the thread. For measurements in surge or bypass tubes with VEGAPULS 45 the max. distance depends on the tube length.
Mounting and installation Emission cone and false echoes The radar signals are focused by the antenna system. The signals leave the antenna in a conical path similar to the beam pattern of a spotlight. This emission cone depends on the antenna used. Any object in this beam cone will reflect the radar signals. Within the first few meters of the beam cone, tubes, struts or other installations can interfere with the measurement.
Mounting and installation 3.2 Measurement of liquids Flange antennas Horn antenna on DIN socket piece Radar sensors are usually mounted on short DIN socket pieces. The lower side of the instrument flange is the reference plane for the measuring range. The antenna must always protrude out of the flange pipe. If the DIN socket piece is longer, please make sure that the horn antenna still protrudes out of the socket.
Mounting and installation Screwed antenna The screwed antenna is used mainly on very small vessels. The antenna fits into even the smallest vessel connection openings (11 /2 “ socket). The socket must not be longer than 135 mm (when used with a longer antenna, not longer than 250 mm). Reference plane ≤ 135 mm Screwed antenna on 1½“ mounting boss 3.3 Measurement in standpipe (surge or bypass tube) General instructions Measurement in a standpipe is preferred in vessels which contain many installations, e.
Mounting and installation Make sure the required upper vent hole in the surge pipe is aligned with the sensor type label. As an alternative to a surge pipe in the vessel, a pipe antenna system outside the vessel in a bypass tube is also possible. The surge and bypass tubes must generally be made of metal. For plastic tubes, a closed, conductive jacket is always required. When using a metal tube with plastic inner coating, make sure that the thickness of the coating is minimal (approx. 2 … 4 mm).
Mounting and installation If enough liquid (300 … 800 mm) remains in the blind lower end of the tube, the portion of the signal that penetrates the liquid and reflects from the tube bottom is sufficiently damped - the sensor can then easily distinguish it from the echo of the liquid surface. In cases where there is not enough liquid at the bottom of the tube, a deflector situated there will carry out the same function. It deflects signals that reach the tube bottom into the standard connection opening.
Mounting and installation Seals on tube connections and tube extensions Guide tube Microwaves are very sensitive to gaps in flange connections. If connections are made without proper care, distinct false echoes as well as increased signal noise can result. Observe the following points: • The applied seal should correspond to the tube inner diameter. • If possible, conductive seals such as conductive PTFE or graphite should be used. • There should be as few seal positions as possible in the guide tube.
Mounting and installation VEGAPULS 45 with integrated measuring tube VEGAPULS 45 sensor version was especially developed for measuring tube applications and is supplied complete with a 27 mm measuring tube. With a measuring tube length up to 4 m, this sensor version can be used, e.g. in existing standpipes.
Mounting and installation If you want to measure inhomogeneous or stratified products in a surge pipe, it must have holes, elongated holes or slots. These openings ensure that the liquid is mixed and corresponds to the liquid in the vessel. Surge pipe with ball valve If a ball valve is mounted in the surge pipe, maintenance and servicing can be carried out without opening the vessel (e.g. if it contains liquid gas or toxic products).
Mounting and installation Guidelines for standpipe construction VEGAPULS 44 Radar sensors for measurement on surge or bypass tubes are used with G 1½ A screwon antenna or in the flange sizes DN 50, DN 80, DN 100 and DN 150. The radar sensors with a DN 50 flange only form a functioning measuring system in conjunction with a measuring tube. Avoid welding through the pipe wall. The pipe must remain smooth inside.
Mounting and installation In products with lower dielectric values (< 4), a part of the radar signal penetrates the medium. If the vessel is nearly empty, echoes are generated by both the product and the vessel bottom. The echo from the vessel bottom can in some cases be stronger than the echo from the product surface. If a deflector is installed below the open end of the measuring tube, the radar signals are scattered and prevented from reaching the vessel bottom.
Mounting and installation Vessel installations Inflowing material Vessel installations, such as e.g. ladders, often cause false echoes. Make sure when planning your measuring location that the radar signals have free access to the measured product. Do not mount the instrument in or above the filling stream. Ensure that you detect the product surface and not the inflowing material.
Mounting and installation Strong product movements 3.5 Common installation mistakes Strong turbulence in the vessel, e.g. caused by powerful stirrers or strong chemical reactions, can seriously interfere with the measurement. A surge or bypass tube (see illustration) of sufficient size always enables reliable and problem-free measurement even if strong turbulence occurs in the vessel, provided there is no product buildup in the tube.
Mounting and installation Parabolic effects on dished or arched vessel tops Round or parabolic tank tops act on the radar signals like a parabolic mirror. If the radar sensor is placed at the focal point of such a parabolic tank top, the sensor receives amplified false echoes. The optimum mounting location is generally in the range of half the vessel radius from the centre. Wrong orientation to the product Weak measuring signals are generated if the sensor is not directly pointed at the product surface.
Mounting and installation Foam generation Standpipe installation mistakes Conductive foam is penetrated to different depths by the radar signals and generates a number of individual (bubble) echoes. At the same time, the signals are damped in foam, similar to the way heat radiation is damped by Styrofoam. Thick, dense, creamy and conductive foam can cause incorrect measurements.
Electrical connection 4 Electrical connection 4.1 Connection and connection cable Safety information As a rule, do all connecting work in the complete absence of line voltage. Always switch off the power supply before you carry out connecting work on the radar sensors. Protect yourself and the instruments, especially when using sensors which do not operate with low voltage.
Electrical connection Earthing the screen only on one end is not always effective, see the following table. The table gives a simple overview of the effectiveness of the different protective measures against electromagnetic pollution. In practice, earthing of both sides is often useful. This allows the option of earthing only one end later by simply disconnecting the other earth contact points of the screen. Why? Actual interference only appears in the operating environment.
Electrical connection Ex protection If an instrument is used in hazardous areas, the respective regulations, conformity certificates and type approvals for systems in Ex areas must be noted (e.g. DIN 0165). Intrinsically safe circuits with more than one active instrument (instrument delivering electrical energy) are not allowed. Special installation regulations (DIN 0165) must be noted. Note! Due to the possibility of potential transfer, earthing on both ends is prohibited in Ex applications.
