VEGAFLEX 83 • 4 … 20 mA/HART - two-wire

41834-EN-120726

Keep in mind that buildup can form on the spacers. Strong buildup

can influence the measurement.

Fig. 8: Position of the spacer or centering weight

1 Rod probe with spacer (PEEK)

2 Cable probe with centering weight

3 Spacer (PEEK) on the gravity weight of a cable probe

Note:

Measurement in a standpipe is not recommended for extremely

adhesive products.

Instructions for the measurement:

•

The 100 % point should not be above the upper tube connection

to the vessel

•

The 0 % point should not be below the lower tube connection to

the vessel

•

A false signal suppression with integrated sensor is generally

recommended to reach the maximum possible accuracy

To compensate the normal bias voltage loss due to the seal materials,

you have to use also disc springs in addition to the flange screws for

fastening PTFE plated flanges.
The flange screws of VEGAFLEX 83 must always be tightened with

a torque of approx. 60 Nm (44 lbf ft) so that the PTFE washer seals

reliably.

flanges
