Safety Information
WARNING!
HIGH PRESSURE AND TEMPERATURE HAZARD
Before removing the senosr, reduce the process pressure to 0 psig and cool down the process temperature.
Failure to reduce the pressure and temperature may cause serious injury to personnel.
CAUTION!
EQUIPMENT DAMAGE
The wetted sensor materials may not be compatible with process composition and operating conditions. Application compatibility is
entirely your responsibility.

Description and Specifications
1 Description and Specifications
1.1 General
Rosemount 225 toroidal conductivity sensors are intended to be used in many
pharmaceutical and food and beverage applications where a sanitary design is required.
These corrosion and fouling resistant sensors are ideal for measuring the concentration of
CIP solutions, detecting product/water interfaces, checking product quality, and
monitoring eleuents in chromatographic separations.
1.2 Unpacking and Inspection
1. Inspect the shipping container. If it is damaged, contact the shipper immediately for
instructions.
2. If there is no apparent damage, remove the sensor.
3. Ensure that all items shown on the packing list are present. If items are missing,
contact your local Customer Care representative.
4. Save the shipping container and packaging.
They can be reused to return the sensor to the factory in case of damage.

2 Quick Start Guide
2 Install
2.1 Installing the sensor
The sensor may be installed in either a tank or pipe using a customer-supplied Tri-Clamp
and tee assembly. Keep at least 1 in. (25 cm) between the sensor and the pipe wall. If
clearance is too small, calibrate the sensor in place. Ensure that the sensor is completely
submerged in liquid.

Install
Prerequisites
2 inch Tri-Clamp
1.
2. 2 inch type 1 gasket
3. 2 inch tank ferrule or tee
Procedure
1. Mount the sensor in the pipe.
2. Mount the sensor in a vertical pipe run with flow from top to bottom.
If the sensor must be mounted in a horizontal pipe run, orient the sensor in the or 9
o'clock position.
3. Ensure that the sensor is completely submerged in liquid to the flange.
