Tightening the Clasp Nut
Installing the HMP368 Probe Through a Ball Valve
Assembly
The ball valve installation kit (Vaisala order code: BALLVALVE-1) is
preferred when connecting the probe to a pressurized process or
pipeline. Use the ball valve set or a 1/2" ball valve assembly with a ball
hole of ø14 mm or more. If you install the probe (ø12 mm) in a process
pipe, please note that the nominal size of the pipe must be at least 1 inch
(2.54 cm). Use the manual press handle to press the probe into the
pressurized (< 10 bar) process or pipeline.
