We have Diaphragm operated Differential Pressure Gauges which do not have any bourden tube in it. These DP Gauges works on Magnetic Coupling principle.
These gauges are suitable for Non-Magnetic Fluids only and more in demand for DP Measurement applications in HVAC / across Heat Exchangers / across Pumps / across Filters / across Strainers, Level Measurement in pressurized tanks, Flow Rate indication across Orifice plate etc.
Ranges : Various DP ranges from 15 mm Wc up to 7 bar
We can also offer Compound ranges.
Sizes : Diaphragm & Piston type Gauges are available in options like 2 1/2”, 3 1/2”, 4”, 4 1/2”, 6” dia.
