Principle structure

Antiseptic/stainless steel thermal flow switch, based on thermal principle, contains two resistors in a closed probe, one heated as the detection resistance and the other not heated as the reference resistance. When the medium flows, the heat on the heating resistance is carried away, the resistance value is changed, and the difference between the two resistors is used as the basis for judging the flow rate.

Characteristic

(1) Conical probe design, can effectively prevent the winding material in the medium;
(2) Fully waterproof shell design, waterproof adjusting knob, no need to remove the sealing screw, can be adjusted arbitrarily, convenient and more reliable;
(3) Suitable for large pipe diameter range, free adjustment of the set point, optional anticorrosive type;
(4) withstand voltage up to 100Bar, indicator light directly display flow, optional relay, analog output or analog switch integrated output;
(5) No moving parts, maintenance-free, easy installation, one type is used for a variety of pipe diameter requirements,
(6) Provide switching output, and use 6 LED real-time display of fluid flow status,
To achieve the following monitoring functions: medium flow, reduce/increase the flow rate medium flow, reduce/increase the flow rate;The presence/absence of medium;Medium flow/static;Monitor the flow velocity in the pipeline, monitor the flow break or prevent the pump from idling.
