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.
