Mounting in a plane wall
In general there are three options available for sensor installation on or
(directly) in a wall:
Screw thread of sensor housing:
The housing has an external thread G½ (16 mm long) for direct mount-
ing on or in the medium separating wall. Its advantage is in the sim-
plicity of installation without special accessories; however, the immer-
sion depth is defined by the probe length in this case.
For detailed description of the mounting procedure refer to subchapter
"Direct mounting"
.
Mounting flange from
SCHMIDT
®
accessories:
Designed as an easy-to-install version for applications without strict
medium separation.
For detailed description of the mounting procedure refer to subchapter
"Mounting with a simple mounting flange"
.
Through-bolt joints from
SCHMIDT
®
accessories:
SCHMIDT Technology
offers four different through-bolt joints that are
primarily designed for installation at pipes. They are also suitable for
the installation on a wall if high mechanical stability is required or the
measuring medium is under overpressure.
For detailed description of the mounting procedure refer to subchapter
"Mounting with a through-bolt joint".
Direct mounting in a wall without a thread
This installation is not suitable for pressure-tight applications and requires
access from both sides for operation.
Drill a bore in the wall with 13 … 14 mm diameter.
Carefully insert measuring probe with an attached protection cap into
the bore so that the mounting block of the enclosure is in contact with
the wall.
Screw on the enclosed fastening nut by hand on the medium side,
turn sensor into required position and tighten fastening nut (wrench
size: HEX27) while holding up the enclosure on the mounting block by
means of HEX30.
Finally, remove protective cap from sensor tip.
