Rectangular diaphragm pressure gauge

Rectangular diaphragm pressure gauge [1] details YEJ-101 type rectangular diaphragm pressure gauge: for boiler ventilation corrode copper alloy and neutral, non-hazardous gas explosion micro-pressure and negative pressure measurement. YEJ-121 Rectangle contacts diaphragm pressure gauge is suitable for boiler ventilation corrode copper alloy and a neutral, non-hazardous gas explosion micro-pressure and negative pressure measurements and has dual two adjustment (lane the sender) the role in order to achieve the position adjustment or limit alarm action. Technical set parameter rectangular diaphragm pressure gauge accuracy rating: 2.5 Use of environmental conditions: -20 ~ 60 ℃ (YEJ-121 is 0 ~ 50 ℃), RH less than 85% and a sharp shock and measured medium pulsation response instrument work had no effect on the electrical specifications: (YEJ-121 type) Setting error: less than 2.5% of full scale-bit digital output contact capacity: AC non inductive load 3A 220V Power supply: AC220V Power consumption: less than 5W pressure port : Φ8 (with a hose with an inner diameter Φ6) rectangular diaphragm gauge measuring range Meaduring range (Pa) Pressure Vacuum Pressure Vacuum Pressure Vacuum (interline) Pressure vacuum (linkage) 0 ~ 160 -160 ~ 0 -80 ~ +? 800 ~ 250-250 ~ 0-120 ~ + ~ 400-400 ~ 1200 ~ 0-200 + 600-600 2000 ~ ~ 0-300 ~ + ~ 1000-1000 ~ 3000 ~ 0-500 + 5000 ~ 1600-1600 ~ 0-800 ~ + 8000 ~ 2500-2500 ~ 0-1200 ~ + 12 000 ~ 4000-4000 ~ 0-2000 ~ + 20 000 ~ 6000-6000 ~ 0-3000 ~ + 30 000 10000 -10,000 ~ 0-5000 ~ + 50 000 ~ 16000-16000 ~ 0-8000 ~ + 80 000 ~ 25000-25000 ~ 0-12000 ~ + 120 000 ~ 40000-40000 ~ 0-20000 ~ + 200 000 ~ 60000-60000 ~ 0-30000 ~ + 30,000 rectangular diaphragm pressure gauge Dimensions (Unit: mm)
