NOTE
The special grommet is intended to be used to seal the multiple cables from the Yokogawa flow
fittings such as FF20.
The designated cables are WU20 sensor cables, which are approximately 5 mm (0.2”) in
diameter, and K1500FV liquid earth cables, which are approximately 2.5 mm (0.1”) in diameter.
For sensor systems using a single cable, like the FU20/FU24 and the PR10, PD20, PF20 and
PS20, the standard gland will accommodate the cable adequately. Single cables between
approximately 6 mm and 12 mm (0.24” and 0.47”) can be sealed properly with these glands and
the standard tule.

The above diagram shows wiring for 4-electrode conductivity sensors, such as SC42-SP34
large bore series. For 2-electrode conductivity sensors, such as SC42-SP36 small bore series,
jumpers must be installed between terminals 13-14 and between terminals 15-16, as shown in
the diagram below.
