Differential pressure gauges have various ranges. Read this article for your differential pressure gauge consideration. Let’s find out with VCR – a leading differential pressure gauge supplier in Viet Nam
1. Differential Pressure Gauge Applications
Differential pressure gauges are widely-used to measure the pressure of fan and blower, air velocity, pressure drops across orifice plates, liquid levels with bubbler systems, and pressures in fluid amplifier or fluidic systems.
It can be used on medical equipment to monitor blood and respiratory pressure.
Magnehelic differential pressure gauges, Dwyer differential pressure gauges, or Macroscopic differential pressure gauges are current customer favorites, so VCR would like to introduce Dwyer Differential Pressure Gauges, which are commonly used.
2. Dwyer gauges specification
Temperature Limit: -15 ~ 60℃

3. Differential pressure gauge consideration
For clean and dust-free rooms, 0-60 Pa gauges should be used
To check the filtration efficiency of the primary, medium and high-efficiency filters, 0-250 Pa, 0-500 Pa, 0-750 Pa is preferred.
For dust removal, 0-2 KPa should be used
4. Measuring ranges
0 ~ 60 Pa
0 ~ 1 KPa 0 ~ 5 KPa -60 ~ 0 ~ 60 Pa
0 ~ 125 Pa 0 ~ 1.5KPa 0 ~ 8 KPa -125 ~ 0 ~ 125 Pa
0 ~ 250 Pa 0 ~ 2 KPa 0 ~ 10 KPa -250 ~ 0 ~ 250 Pa
0 ~ 500 Pa 0 ~ 2,5KPa 0 ~ 15 KPa -500 ~ 0 ~ 500 Pa
0 ~ 750 Pa 0 ~ 3 KPa 0 ~ 25 KPa -1000 ~ 0 ~ 1000 Pa
