Proline Promass 80 PROFIBUS PA Installation
17
Horizontal (Promass H, I, S, P):
Promass H, I, S and P can be installed in any orientation in a horizontal pipe run.
In order to ensure that the maximum permissible ambient temperature for the transmitter
(–20 to +60 °C (–4 to +140° F), optional –40 to +60 °C (–40 to +140 °F)) is not exceeded, we
recommend the following orientations:
m = For fluids with very high temperatures > 200 °C (392 °F), we recommend the horizontal
orientation with the transmitter head pointing downwards (Fig. H2) or the vertical orientation
(Fig. V).
n = For fluids with low temperatures, we recommend the horizontal orientation with the
transmitter head pointing upwards (Fig. H1) or the vertical orientation (Fig. V).
