VA 409 Flow direction switch for compressed air systems
The new thermal flow direction switch VA 409 with direction indication serves for determination of the flow direction of compressed air and gases especially in closed circular pipelines.
 
By means of VA 409 with flow direction indication the flow direction of the compressed air can be determined quickly and safely. Compared with the former mechanical paddle flow switches VA 409 is able to detect even the smallest changes in the flow direction quickly and without any mechanical movement.
 
The direction information in form of a potential-free contact (normally closed max. 60 VDC, 0.5 A) is transferred to the consumption sensors VA 500/ VA 520 or to a separate building management system (mbs). Two LEDs show the flow direction.
 
In connection with 2 consumption sensors VA 500/ VA 520 incoming and outflowing compressed air in closed circular pipelines can be measured precisely.

The special features of VA 409
detects smallest changes <0.1 m/s referred to 20°C and 1000 mbar
no mechanical wear parts
easy installation under pressure
