Product Description
Products Description
D520M/7DDP Micro Pressure Controller adopts diaphragm sensor, is applicable to neutral oil, gas and water.
Controller set value which is 0.2~25KPa is adjustable; working pressure range is 0-0.16MPa. With tri-diaphragm structure, working pressure is high, setting value is stable.
Main Technical Parameters
Working viscosity: <1×10-3m2/s
Service life: 105 times circling (200V AC/6A)
Vibration-resistant: 10m/s2
Housing: IP54
Rated load: Vmax=380V AC Imax=6A(resistance)
Pmax=600V A
Environment temperature: -10℃~+55℃
Medium temperature: stable working temperature 0~+90℃
Repeatability error ≤2%

Note: medium peak pressure from two pressure joints can not exceed rated pressure.
1, it’s better if setting value is at middle of controller adjustable range. (20%-80% of upper limit)
2, on and off current shall not be larger than rated value. (not more than 60% of rated value)
3, when mounted outdoor, enough protection is required to avoid it from corrosive gas, tremendous changed environment temperature, solar radiation, water etc.
4, for liquid medium which has pressure peak and pulse pressure, you can mount one pressure damper joint is required to eliminate bad influence from pressure peak.
