    With pressures under -0.2 bar (-20 kPa) you should use a different measuring principle, e.g. radar or guided radar (TDR). Mounting instructions Screwing in Screw VEGASON 61 into the mounting socket with an appropriate spanner applied to the hexagon of the process fitting. Max. torque see chapter " Technical data". Warning: The housing must not be used to screw the instrument in! Applying tightening force can damage internal parts of the housing.

  • Page 15 4 Mounting Fig. 7: Recommended socket mounting If the reflective properties of the medium are good, you can mount VEGASON 61 on sockets which are higher than the length of the transducer. You will find recommended values for socket heights in the following illustration. The socket end should be smooth and burr-free, if possible also rounded. Carry out a false signal suppression.
