Application
Definition of pressure
Widely applied in measuring the pressure of fans,
resistance/wind velocity/oven pressure/differential
pressure of filter, and monitoring the gas content in the
air in process of combustion.
The pressure in this manual refers to the intensity
of pressure, the force applied on a square unit.
absolute pressure： Difference between the reading
and the absolute zero.
Positive pressure means that the right pressure is
bigger than the left one.
Negative pressure means that the left pressure is
bigger than the right one.
