I.Product introduction
RST - 200 series thermal flow switch adopted widely used in aerospace and automobile precision electronic components, reliable stability, the circuit design, make the traffic signal is more accurate and stable, has been widely used in steel, metallurgy, pharmacy, chemical industry, heat flow switch is designed on the basis of the principle of heat exchange, probe the built-in heating module as well as the thermal module, heating module of heat dissipation and the flow velocity is closely related to the body, there is no medium flow, if the pipe thermal circuit the received signal is a fixed value; When the fluid medium flows through the probe, the signal received by the thermal sensor circuit changes with the velocity change of the medium. The thermal sensor circuit converts the temperature difference signal of the heating module and the thermal sensor module into electrical signal, which is then converted by the processor into PNP/NPN/ relay signal output. It can be used in gas and hydraulic system, circulating water, cutting fluid and lubricating oil cut-off monitoring, and idling protection of pump.
II.Product features
LED clear indication flow state all stainless steel integrated structure overall size compact, high reliability integrated circuit design no moving parts, maintenance free installation convenient one model is applicable to a variety of pipe diameter requirements switch volume adjustable almost no pressure loss overall IP67 protection class
