83 MountingVEGAPULS 69 • 4 … 20 mA/HART - four-wire47255-EN-1408013 Mounting3.1 Mounting preparations, mounting strapThe strap is supplied unassembled and must be screwed to thesensor before setup with three hexagon screws M5 x 10 and springwashers. Max. torque, see chapter "Technical data". Required tools:Allen wrench size 4.There are two ways to screw the strap onto the sensor. Dependingon the selected version, the sensors can be swivelled in the strap asfollows:• Single chamber housing– Angle of inclination 180°, infinitely variable– Angle of inclination in three steps 0°, 90° and 180°• Double chamber housing– Angle of inclination 90°, infinitely variable– Angle of inclination in two steps 0° and 90°3.2 Mounting instructionsRadar sensors for level measurement emit electromagnetic waves.The polarization is the direction of the electrical component of thesewaves.The polarization direction is marked by a nose on the housing, seefollowing drawing:1Fig. 2: Position of the polarisation1 Nose for marking the direction of polarisationInformation:When the housing is rotated, the direction of polarization changesand hence the influence of the false echo on the measured value.Please keep this in mind when mounting or making changes later.Mount the sensor at least 200 mm (7.874 in) away from the vesselwall.PolarisationInstallation position
