VEGA VEGAKON 61 - Transistor (NPN_PNP) - Manual (Page 9)

4 Mounting
4 .1 General instructions
Make sure that all parts of the instrument exposed to the process, in
particular the sensor element, process seal and process fitting, are
suitable for the existing process conditions. These include above all
the process pressure, process temperature as well as the chemical
properties of the medium.
You can find the specifications in chapter "Technical data" or on the
type label.
Use the recommended cables (see chapter "Connecting to power
supply") and tighten the cable gland.
You can give your VEGAKON 61 additional protection against
moisture penetration by leading the connection cable downward in
front of the cable entry. For this reason, the housing can be turned
without any tools by 270°. Rain and condensation water can thus drain
off. This applies mainly to outdoor mounting as well as installation in
areas where high humidity is expected (e.g. through cleaning
processes) or on cooled or heated vessels.
Fig. 3: Measures against moisture penetration
The process fitting must be sealed if there is gauge or low pressure in
the vessel. Before use, check if the seal material is resistant against
the measured product and the process temperature.
The max. permissible pressure is specified in chapter "Technical data"
or on the type label of the sensor.
4 .2 Mounting instructions
Remove the supplied seal from the thread of VEGAKON 61. This seal
is not required when using the welded socket with O-ring in front.
