	INSTALLATION

2.3.4 Inductive Loops.

The Model 5081-T conductivity transmitter is designed to make accurate measurements while in contact with the process stream. Measurements can also be tailored to high temperature and/or high pressure streams.

2.3.5 Sensor Selection.

All Rosemount Analytical contacting conductivity sensors with PT100 RTD or PT1000 RTD are compatible with the Model 5081-T transmitter. Please refer to Figures 3-5 thru 3-7 for appropriate sensor to transmitter wiring. The sensor cable should be routed through the left inlet closest to the connector.

Choose an inductive conductivity sensor that is appropriate for your process conditions and range of conductivity meas- urement.

RECOMMENDED RANGES FOR TOROIDAL SENSORS

Conductivity Sensor
Model Number	226	228	225	222 (1in.)	222 (2 in.)	242
Nominal Cell Constant	1.0	3.0	3.0	6.0	4.0	*
Min. Conductivity (∝S/cm)	50	200	200	500	500	100*
Max. Conductivity (∝S/cm)	1,000,000	2,000,000	2,000,000	2,000,000	2,000,000	2,000,000*

* Model 242 values depend on sensor configuration and wiring.

NOTE: Values shown are for 25°C conductivity with a temperature slope of 2% per degree C. The maximum range value will be lower for solutions with a higher temperature slope. Minimum conductivity depends on sensor.
