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.

Summary
MODEL 228 INSTALLATION INSTALLATION Keep at least 1 in. (2.5 cm) between the sensor and pipe walls. If the clearance is too small, calibrate the sensorin place. Ensure that the sensor is completely submerged in liquid. Mounting the sensor in a vertical pipe run withthe flow from bottom to top is bes...
MODEL 228 WIRING FIGURE11. Wiring sensors through a remote junction box Wire sensors point to point. For wiring at the analyzer end, refer to the appropriate analyzer wiring diagram. For interconnecting cable 23294-00, use the 2265-54 wiring diagram. For interconnecting cable 23294-04 and 23294-05, ...
