Description of operation

Function as duct pressure controllerThe 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 compensatesfor the control deviations with no persistent error. The setpoint XS can be adjusted externally via con-nection 6, with the set value becoming the minimum limitation.

Function as transducerThe 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 thepressure increases, so does the output pressure.

Intended useThis product is only suitable for the purpose intended by the manufacturer, as described in the “De-scription of operation” section.All related product documents must also be adhered to. Changing or converting the product is not ad-missible.

Engineering and fitting notesUpright mounting is not permitted.

DisposalWhen disposing of the product, observe the currently applicable local laws.More information on materials can be found in the Declaration on materials and the environment forthis product.
