When pressure is applied to the Bourdon Tube, it extends vertically. This vertical movement of
Bourdon Tube is delivered to the Movement, and the Movement changes this vertical movement
User's Manual
Movement is consist of lever and gear, and its main role is converting vertical movement into a
rotating motion.
Generally, the vertical movement of Bourdon Tube ranges from 3~4mm, and its principle is to
point currently applied pressure by using a turn angle 270º
Therefore, Bourdon Tube and Movement are the most important, and these parts must be well
assembled in the pressure gauge because these parts leads to precise machining accurracy.
7. Contact Point Working Type and Connection
1) HIGH ALARM
As a Single Contact, when the pressure reaches higher than its set point, User can
set it as either ON or Off.
2) LOW ALARM
As a Single set point, when the pressure reaches lower than its set point, either User
can set it as ON or Off.
