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. Battery operated Digital DP Gauges are available in 4" dia. External powered Digital DP Gauges are available in Panel mounted or, Wall mounted versions. Connection : 1/4” NPT-F (Standard) Accuracy : + / - 2% FSD (Ascending) Working Pressure : Various options up to 400 bar Porting : Options like In – Line. Back or, Bottom Calibration : Non-Linear, spread over 65 degrees to 75 degrees Arc. Sensing Element : Small Convoluted Diaphragm Wetted parts : Aluminium, Brass, SS 316, Inductrial Plastic, Buna N, Viton Max. Working Temp.: with Buna N as sealants Max. 60 degree C & with Viton max. 200 degree C.. Enclosure : IP 65 Certification : CE Single or, Duel Reed Switch Contacts can be provided along with the Gauge, either in IP65 or, Flameproof enclosure.
