YD Digital Pressure Gauge / YDA Intrinsically-Safe Explosion-proof Digital Pressure Gauge
YD Digital Pressure Gauge / YDA Intrinsically-Safe Explosion-proof Digital Pressure Gauge
YD & YDA stainless steel digital pressure gauges. YD for general use; YDA is Ex intrinsically safe type for hazardous areas. IP66, LCD display, multi pressure units, for petrochemical & power industries.
Product Overview
Stainless-steel airtight-enclosure digital pressure gauge. YD is for general-site pressure measurement; YDA is
intrinsically-safe explosion-proof variant for hazardous-area deployment, suitable for outdoor field installation.
Multiple configurable options adapt to diverse working-condition requirements.
Available Options
Dial Diameter: Φ100
Mounting Types: Non code- Bottom mounting T- Bottom mounting with back flange
Z- Back mounting ZT- Back panel mount from front flange
Industry Applications
YD Model: Measures positive, negative and absolute pressure for non-explosive, non-crystallizing, non-solidifying
liquid & gas media non-corrosive to Cr-Ni stainless steel.
YDA Model: Developed for petroleum, chemical, metallurgy and power-station industries. Applicable in hazardous areas with Class IIA, IIB, IIC flammable-gas-steam-air explosive mixtures; measures positive, negative and absolute pressure
