Non-Immersion Nozzle Thermocouple
The non-immersion nozzle style is typically used to measure the temperature of the nozzle.  The rotating bolt, when
tightened, seats the tip against the process.  The tip is not in the plastic flow.  This type of construction can be
used in numerous applications.  A 1/4-28 bolt is the most common size used.  Other sizes are available.  Custom
construction for unusual applications are also available.
