Note: The ISC40 sensor type GG and TG are supplied with a Viton gasket. This gasket may
be used with the older series of ISC40FS fittings. It should be discarded when the
sensor is mounted in combination with the ISC40FS type FCSA and PCSA.
9.2 Installation of ISC40 sensor in ISC40FS
The key difference between a sensor adapter and a subassembly is, that with subassembly
installation the sensor can be removed from the process installation without removing
the subassembly first. This allows easier access to the sensor for maintenance activities.
Generally, the subassembly consists of three parts of which one part is fitted permanently
to the process installation (welded or threaded); the second part is fitted to the sensor and
the third part holds the earlier parts together. In addition to these parts there are elastomeric
seals were appropriate. Standard O-ring material is Viton, other O-ring materials are
available as sparepart (see Figs 15 and 16).
