VEGASWING 66 • - two-wire

44952-EN-130805

The max. permissible pressure is specified in chapter "Technical

data" or on the type label of the sensor.
Note:

Seal for instruments with process fitting thread
The thread and the seal form on the mounting boss correspond to

DIN 3852, part 1, screwed plug Form B (sealing via metallic sealing

edge). In this case, no seal is required.

Instruments for high temperatures have a temperature adapter be-

tween process fitting and electronics housing. This is used for thermal

decoupling of the electronics from high process temperatures.
Information:

The temperature adapter may be embedded in the vessel insulation

only up to max. 50 mm (1.97 in). Only then is a reliable temperature

decoupling guaranteed.

If VEGASWING 66 is mounted in the filling stream, unwanted false

measurement signals can be generated. For this reason, mount VE-

GASWING 66 at a position in the vessel where no disturbances, e.g.

from filling openings, agitators, etc., can occur.
This applies particularly to instrument types with long extension tube.
