INSTALLATION
The sensor may be installed
in either a tank or pipe using
a customer-supplied Tri-
clamp and tee assembly.
The sensor requires a 2-inch
Tri-clamp, a 2-inch type 1
gasket, and a 2-inch tank
ferrule or tee.
Keep at least 1 in. (25 cm)
between sensor and pipe
wall. If clearance is too small,
calibrate the sensor in place.
Ensure that the sensor is
completely submerged in liq-
uid to the flange. Mounting
the sensor in a vertical pipe
run with the flow from bottom
to top is best. If the sensor
must be mounted in a hori-
zontal pipe run, orient the
sensor in the 3 o’clock or 9
o’clock position.

WARNING
Before removing the sensor, be absolutely certain
that the process pressure is reduced to 0 psig and
the process temperature is lowered to a safe level!
CAUTION
The wetted sensor materials may not be compatible
with process com position and operating conditions.
Application compat ibility is entirely the responsi-
bility of the user.
CAUTION
SENSOR/PROCESS
APPLICATION COMPATIBILITY
1 Sensor meets 3A sanitary requirements for sensors and sensor fittings and connections used on milk and milk products
equipment (74-03).

For wiring at the analyzer end, refer to the appropriate analyzer wiring diagram. For interconnecting cable 23294-00, use the ...
6 MODEL 225 CALIBRATION CALIBRATION The nominal cell constant of the Model 225 sensor is2.7/cm. The error in the cell constant is about ± 10%, so conductivity readings made using the nominal cell con-stant will have an error of at least ± 10%. Wall effects, discussed below, will likely make the erro...
