n ORP Measurement
The ORP measurement uses the same sensor input module as the pH measurement. It is not
uncommon to measure ORP as process variable and a pH Glass electrode as reference. This is
the case with rH measurement and with pH compensated ORP measurement.
Conventional ORP sensors are connected to the module as follows:
11 Temperature
12 Temperature
13 Reference
14 Solution ground
15 Metal (measure)
16 Shield
17 Shield
FLXA21
REFTC Liquid
Earth
ORP
For conventional ORP sensors, the jumpers are placed as illustrated:

pH Compensated ORP sensors are connected to the module as follows:
