Knowledge About Differential Pressure Gauge
FAQs
What is a differential pressure gauge?
A differential pressure gauge is a device used to measure the pressure difference between two different environments.
Why is it necessary to measure differential pressure in cleanrooms?
By measuring the pressure difference between air environments, we can determine the cleanliness level of the environment being measured.
How many types of differential pressure gauges are there?
Differential pressure gauges can be classified based on: Measurement range (-60-60Pa, 0-60Pa, 0-125Pa, 0-250Pa, 0-500Pa, etc.), Usage (Cleanroom, Filter), Measurement method (Mechanical, Electronic).
What are the applications of differential pressure gauges in cleanrooms?
In cleanrooms, differential pressure gauges are used to measure pressure differentials between rooms and monitor the filter integrity of cleanroom equipment (HEPA Box, FFU, Pass Box, etc.).
What documents are needed when purchasing a differential pressure gauge?
Here are some documents needed when purchasing a differential pressure gauge: CO - Certificate of Origin; CQ - Certificate of Quality; Inspection certificate; Standardization certificate, etc.
What measurement ranges do differential pressure gauges for filters use?
In cleanrooms, differential pressure gauges for filters typically use measurement ranges such as 0-125Pa, 0-250Pa, 0-500Pa, 0-750Pa, etc., depending on practical needs.
