Description

CS-iTEC FLOW DIRECTONAL SWITCH FOR COMPRESSED AIR AND GASES

The thermal mass flow direction switch S 409 allows the detection of an existing flow and the direction of the flow. It can be used in compressed air and non-corrosive gases.
The sensor element is very robust and completely of stainless steel. Through a 1/2” G-type ball valve the switch can be inserted into the pipe under pressure.
The flow and direction information is output through 2 normally open relay switches. This signals can be transferred to the CS flow sensor to activate and deactivate the flow measurement depending on the flow direction.
Application

Connection of S 330 to S 450 via flow switch

 
Connection of S 330 to two S 400 with flow switch
