4 Mounting 4 Mounting 4.1 General instructions Screwing in With instruments with threaded process fitting, suitable tools must be applied for tightening the hexagon. Warning: The housing must not be used to screw the instrument in! Applying tightening force can damage internal parts of the housing. Moisture Use the recommended cables (see chapter "Connecting to power supply") and tighten the cable gland.
4 Mounting Note: The radar sensor with rinsing air connection or antenna extension is provided with a notch on the antenna socket. This notch must correspond to the marking on the hexagon of the process fitting (the marking specifies the position of the polarisation level of the radar signal). 1 2 3 4 Fig. 2: Dismounting of the horn antenna 1 2 3 4 Marking of the polarisation plane Notch at the antenna socket Hexagon screws on the antenna socket Antenna 4.
4 Mounting Note: A damaged O-ring seal must be replaced: FKM (Viton) article no. 2.28248, FFKM (Kalrez 6375) article no. 2.27351 8 Remount the parabolic antenna (4) 9 Fasten compression nut (1) with a wrench (width across flats 41), torque max. 50 Nm 10 Fasten counter nut (2) with a wrench (width across flats 36), torque max. 40 Nm Note: Take note for the version with rinsing air connection that the holes in the antenna and in the process fitting correspond.
4 Mounting 11 Fig. 4: Position of the polarisation level 1 Mounting position Marking hole Mount the sensor at least 200 mm (7.874 in) away from the vessel wall. 1 > 200 mm (7.87") Fig. 5: Mounting of the radar sensor on round vessel tops If you cannot keep this distance you should carry out a false echo storage before setup. This applies mainly if buildup on the vessel wall is expected. In this case, we recommend repeating a false echo storage later with existing buildup.
4 Mounting Fig. 6: Mounting of the radar sensor with inflowing medium The socket piece should be dimensioned in such a way that the antenna end protrudes slightly out of the socket. 36535-EN-100607 ca. 10 mm Socket Fig.
4 Mounting When using a swivelling holder, keep in mind that the distance between antenna and socket gets smaller as the inclination of the sensor increases. Additional false reflections may be generated which can influence the measuring result at close range. Fig. 8: Distance between antenna and socket h max. If the medium has good reflective properties, VEGAPULS 68 can also be mounted on a longer socket piece. Recommended values for socket heights are specified in the following illustration.

The antenna length can be selected (either ex works or later) to allow the antenna to protrude slightly out of the end of the mounting socket.
4 Mounting Fig. 10: Orientation If mounting in the center of the silo is not possible, the sensor can be directed to the vessel center by means of an optional swivelling holder. The following description gives an overview on the determination of the necessary angle of inclination.
4 Mounting d α a Fig. 11: Proposal for installation after orientation VEGAPULS 68 The angle of inclination depends on the vessel dimensions. It can be easily checked with a suitable level or water leve on the sensor. 36535-EN-100607 The following chart specifies the distance "a" between installation position and vessel centre dependent on the measuring distance for inclination angles of 2° … 10°. Distance d 2° (m) 4° 6° 8° 10° 2 0.1 0.1 0.2 0.3 0.4 4 0.1 0.3 0.4 0.6 0.7 6 0.2 0.

The necessary angle of inclination of 4° can be read out from this chart.
4 Mounting Fig. 12: Cover smooth profiles with deflectors Agitators If there are agitators in the vessel, a false signal suppression should be carried out with the agitators in motion. This ensures that the interfering reflections from the agitators are saved with the blades in different positions. Fig. 13: Agitators Large material heaps are detected with several sensors, which can be mounted on e.g. traverse cranes. For this type of application, it is best to orient the sensor toward the solid surface.
4 Mounting Fig. 14: Radar sensors on traverse crane Information: Keep in mind that for these applications, the sensors are designed for relatively slow level changes. When using VEGAPULS 68 on a movable bracket, the max. measuring rate must be observed (see chapter "Technical data"). Mounting in the vessel insulation Instruments for a temperature range up to 250 °C or up to 450 °C have a distance piece between process fitting and electronics housing.
4 Mounting max. 50 mm (1.97") 1 2 3 Fig. 15: Mounting of the instrument with insulated vessels. 1 2 3 Installation in subsurface enclosures Electronics housing Distance piece Vessel insulation For level measurements in concrete silos, the sensors are often mounted in protective boxes. These boxes can be for example metallic, closed subsurface enclosures. Minimal amounts of stray radiation from the sensor can be reflected and strengthened by the walls of the subsurface enclosures.
4 Mounting Mounting in multiple chamber silo The silo walls of multiple chamber silos are often made of profile walls, such as e.g. profile sheeting, to ensure the required stability. If the radar sensor is mounted very close to a heavily structured vessel wall, considerable false reflections can be generated. Hence the sensor should be mounted at a large distance from the separating wall.
4 Mounting Fig. 18: Orientation of VEGAPULS 68 for emptying in the silo center Dust layers To avoid strong buildup and dust in the antenna system, the sensor should not be mounted directly at the dust extraction of the vessel. In case of extreme dust in the antenna system, VEGAPULS 68 is available with purging air connection. The air is distributed via channels in the antenna system and keeps it virtually free of dust. 36535-EN-100607 Fig.
4 Mounting Fig. 20: Purging air connection with parabolic antenna The practice has shown that a pressure of approx. 0.2 … 1 bar provides a sufficient air flow (see diagram in chapter "Technical data", "Purging air connection".
5 Connecting to power supply 5 Connecting to power supply 5.1 Preparing the connection Safety instructions Always keep in mind the following safety instructions: l l Voltage supply Connect only in the complete absence of line voltage If overvoltages are expected, install overvoltage arresters Power supply and current signal are carried on the same two-wire cable. The voltage supply range can differ depending on the instrument version. The data for power supply are specified in chapter "Technical data".
5 Connecting to power supply Cable screening and grounding If screened cable is necessary, connect the cable screen on both ends to ground potential. In the sensor, the screen must be connected directly to the internal ground terminal. The ground terminal on the outside of the housing must be connected to the potential equalisation (low impedance). If potential equalisation currents are expected, the connection on the processing side must be made via a ceramic capacitor (e. g. 1 nF, 1500 V).
5 Connecting to power supply 5 Insert the cable into the sensor through the cable entry Fig. 21: Connection steps 5 and 6 6 Insert the wire ends into the terminals according to the wiring plan Information: Solid cores as well as flexible cores with cable end sleeves are inserted directly into the terminal openings. In case of flexible cores without end sleeves, press the terminal head with a small screwdriver; the terminal opening is freed. When the screwdriver is released, the terminal closes again.
