LOOP SPECIFICATIONS

LOOP ACCURACY: With a standard Model 228 or 225 sensor with 20' cable, laboratory accuracy at 25°C can be as good as ±2% of reading and ±50 µS/cm.

To achieve optimum performance, standardize the sen- sor in the process at the conductivity and temperature of interest.

Results under real process conditions, at different tem- peratures, or using other sensors may differ from above.

RTD ACCURACY: Utilizing a perfect 100 Ohm RTD after 1 point temperature standardiztion, temperature read- ing can be as good as ±0.5°C.

RECOMMENDED SENSORS:

Model 222 Flow-Through

Model 225 Clean-In-Place (CIP)

Model 226 Submersion/Insertion

Model 228 Submersion/Insertion/Retractable

Model 242 Flow-Through*

*Model 242-06 or 242-08 with 5081T do not have Intrinsically Safe approvals.

* 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

2 value will be lower for solutions with a higher temperature slope. Minimum conductivity depends on sensor.
