Application
The explosion proof electrically heated M&Csample
lines series 3/4/5-N/M EX may be used
with advantage in gas analysis systems. Their
application helps avoid errors and acts as frost
protection during transport of the sample gas
from the sample point to the gas conditioning
system or directly to a heated analyser
(above dew point).
Description
The explosion proof electrically heated M&Csample
lines 3/4/5-N/M EX are supplied
according to clients requirements compley
fabricated in the factory with connections
and ends to a fixed length.
Several options can be supplied:
2 different temperature versions (N-100 °C/
M-200 °C ), EX T3
3 tube/pipe versions (3/4/5) with either N 4/6,
6/8 or DN 8/10 mm each as well as
3 inlet connections (C/D/E) and
3 end connections (W/Y/Z).
The robust construction of the sample line
consists of a medium tube/pipe inside a thermally
conductive stainless steel mesh which
acts also as protection and support. The heat
conductor is also coiled around the stainless
steel protective mesh followed by a further
two (2) layers of thermal insulation. The outer
cover is a corrugated tube out of polyamide.
The ends of the sample line are finished
with heat resistant Silicone materials, and the
entire construction ensures that the complete
sample line is properly heated, including the
ends.
The explosion proof sample lines are
equipped with two Ex-PT100 intrinsically
safe 2GD according to ATEX for temperature
detection.
