DRpro pressure controllers control the pressure in ventilation ducts for supply air or exhaust air in ventilation systems or in associated rooms. They can be installed and operated in any mounting position in ventilation ducts for supply and exhaust air. The casing and the consoles for the control mechanism are made of galvanised sheet steel. The damper blade for pressure regulation is centrally mounted and fitted with a circumferential seal. The bearing axles are made of stainless steel and are guided in special bearing bushes. The measuring cross is made of aluminium
The control components consist of static or dynamic sensors, actuators with standard, high speed or spring return and a controller. Sensor and controller are mounted on mounting consoles that can be manually folded or offset when space is limited. The DRpro pressure controller is controlled and electrically connected either analogue or via MP-Bus®. All control components enable the "Constant" and "Variable 0 - 10 V, 2 - 10 V, adjustable" operating modes. Override controls, parallel operation and sequential circuits are possible. The pressure controllers allow high accuracy with only ± 5 % to ± 10 % deviation from the actual pressure.
