RUP: Differential pressure controller/transducer, centair
How energy efficiency is improved
Efficient duct pressure control for optimum system operation
Features
• Conversion of measured differential pressures into a pneumatic
standard signal 0.2...1.0 bar by a pressure sensor
• PI controller
• Easy to use, PI-controller not operational when used only as a transducer
• Differential pressure measuring range up to 500 Pa and 4000 Pa
• Front plate printed with circuit diagrams for easy identification of the controller functions
• Compressed-air connections with Rp⅛" female thread

Description of operation
Function as duct pressure controller
The pressure sensor converts the pressure difference to be measured into a standard signal
(0.2...1.0 bar). This actual value signal is compared to the setpoint XS. The PI controller compensates
for the control deviations with no persistent error. The setpoint XS can be adjusted externally via connection 6, with the set value becoming the minimum limitation.
Function as transducer
The pressure sensor converts the pressure difference to be measured into a standard signal
(0.2...1.0 bar). The output signal at connection 3 is proportional to the pressure difference. As the
pressure increases, so does the output pressure.
Intended use
This product is only suitable for the purpose intended by the manufacturer, as described in the “Description of operation” section.
All related product documents must also be adhered to. Changing or converting the product is not admissible.
Engineering and fitting notes
Upright mounting is not permitted.
Disposal
When disposing of the product, observe the currently applicable local laws.
