11.1.3 Process connections
Flange AISI 316 SS 2” or AISI 316 SS DN50, for the type –V an adjustable optional flange
is available with ANSI 2” 150 lbs and DN50 PN10 hole pattern.
Note: The ISC40 sensor type -GG and -TG are supplied with a Viton gasket. This gasket
may be used with the older series of ISC40FD fittings. It should be discarded when
the sensor is mounted in combination with the ISC40FD type -S and -V.
11.2 Installation of ISC40 sensor in ISC40FD
Installation of the immersion fittings involves two steps:
• Installation of the sensor
The sensor has to be mounted in the immersion fitting (see Fig 22).
• Installation in the application
o On a railing or stanchion
For this purpose the immersion fitting has an optional rail mounting kit /MS1. This kit
consists of a piece of guide pipe and two pipe clamps. The guide pipe is mounted
horizontally to the stanchion using one pipe clamp. The second pipe clamp connects
the guide pipe to the immersion fitting. The distance between the pipe clamps
determines the distance between the stanchion and immersion fitting (see Fig 23).
o With flange
For this purpose a stainless steel immersion fitting can be ordered as type -
SFD (DN50) or type –SFA (2”). The PVC immersion fitting has an optional depth
adjustable mounting flange /FA (with DN50 PN10 and ANSI 2” 150 lbs hole pattern)
which is illustrated in Fig 24. You must assure that the mating flange has the same
hole pattern as the supplied flange.
