3.6.2 Sensor wiring
Refer to figure 3-9, which includes drawings that outline sensor wiring.
The SC450G can be used with a wide range of sensor types. The sensor system fall into
two categories, the ones that use fixed cables and the ones with separate cables.
To connect sensors with fixed cables, simply match the terminal numbers in the instrument
with the identification numbers on the cable ends.
Figure 3.9 Sensor wiring diagrams
3.6.3 Other sensor systems
To connect other sensor systems, follow the general pattern of the terminal connections as
listed below:
11 and 12: Always used for temperature compensation resistor input.
13 and 14: Normally used for the outer electrode
15 and 16: Used for inner electrode
In case a 4-electrode measuring system will be used, 14 and 16 should be used for the
current electrodes. Please ensure that shielded cabling will be used.
In below figure this is shown in a schematic way.
