Explosion proof differential pressure controllerDetailed product description：

The D520M/7DD explosion-proof differential pressure controller adopts a diaphragm type sensor with an explosion-proof rating of de Ⅱ CT5. Can be used for general gas media such as air, as well as liquid media such as water and oil. The set value of the controller can be adjusted within the range of 0-25kPa.

Technical specifications of D520M/7DD explosion-proof differential pressure controller
Working viscosity: ＜ 1 × 10-3m2/s
Explosion proof grade: Exde II CT5
Repetitive error: ≤ 2%
Environmental temperature: 0-55 ℃
Medium temperature: stable working temperature 0-60 ℃, short-term working temperature 95 ℃. If the above temperature is exceeded, there must be a sufficiently long cooling pressure pipe (more than 3 meters) and a buffer installed in front of the controller. The high and low pressure cutoff valves in the buffer can only be opened after the medium has cooled to the specified temperature in front of the buffer.
Installation position: The cover plate with glass panel should be perpendicular to the horizontal direction. It is also preferable for the membrane to be perpendicular to the water surface.
Anti vibration performance: Max: 20m/s2
Shell protection level: IP54
Contact capacity: DC 250V 0.25A (resistive) 60Wmax
AC 250V 5A (resistive) 1250Famax
