Flowswitch DW-N – Reliable monitoring! Easy to use!
;)
Flowswitch with adjustable switching point and optical switching display using glow lamp. The DW-N is based on the extremely reliable way deflection system. The pendulum system with the pressure plate (deflector) is moved by the flowing medium against the strength of a spring.
A metal bellow seals the system from the medium to the measuring and display part. The movement transmission is done by force. A micro-switch arranged in the measuring part and a control lamp are activated. Corresponding switching processes are triggered by this micro-switch.
If the T-part of the DW-N device types is affected by calcification, debris or dirt, there is a message ‘no throughflow’. This means that it is virtually impossible for the system to stop in a position in which flow is indicated but where there is none.
- simple adjustment of the switching points in accordance with small scale
- compulsory movement transmission to the micro-switch
- hermetic separation of the medium from the micro-switch using the bellows
- insensitive to pollution and magnet fields
- high electrical resilience
- maximum operating reliability and serviceability
- can be supplied for all flow directions and installation positions
- also available in Ex-version
- Version with two switches is available
