- ZHE JIANG LEFOO CONTROLS CO.,LTD
- product brand:LEFOO
- Numéro de stand：W4G15
- product specification:FS213
- product category:Refrigeration Equipment-Components for refrigerating systems and plants -Pressure switches
- product introduction:Principle、Structure:There are two resistors in the enclosed probebased on the thermal principle.One of them isheated as the detection resistor and the other isnot heated.As the reference resistance, whenthe medium flows, the heat on the heatingresistor is taken away. The resistance value ischanged，the two resistance differences areused as the basis for judging the flow rate.Features:
No moving parts，maintenance-free，easy toinstall, one type can meet a variety of diameterrequirements. Switching value is continuouslyadjustable，very low pressure loss，compactstructure，LED display flow trends and switchstatus.
Application:Gas-liquid dual-use type, used for pneumaticand hydraulic systems， circulating water,cutting fluid and lubricating oil flow monitoring, and pump idling protection.
