VAV Controller/Actuator - Overview

The damper actuator type 27SV contains a dynamic differential pressure sensor. The volume flow is measured according to the defined flow direction. An integrated microprocessor controls measurement and control of the actuator and communication. For pressure independent control of VAV boxes. The actuator can be controlled by proportional controllers, positioners or DDC systems. Simple realisation of different operating modes can be utilised by using override control signals.

• extreme precision
• high resolution
• wide measuring range
• immune to dust contamination
• damage-proof
• unaffected by position
• any length (up to 10 m) possible for the supply
• hose of volume flow to be measured
