Wiring Diagram For Liquid Level Switches. 50hz60hz up to 380v rated supply voltage for liquid. The second switch h goes at the maximum desired level.
2 install the actuator assembly into the side with the no marking and tighten. When the liquid is below both switches they are both closed. As the liquid fills past the first switch it opens.
An optional sil2 rating enhances reliability while the switch makes installation and commissioning easier.
Here is a simple level switch circuit that switches on one relay and switches off another relay when the fluid level exceeds the set limitthis circuit is a modification of the simple water level indicator previously postedwhen the water level touches the probes positive supply is connected to the base of q1 through fluidthis makes transistor q1 onbase of q2 is. Vertical liquid level float switches can be mounted in the top or the bottom of the tank. Slide the cover down the cable and fasten it to the body of the switch with the 4 screws provided.
