3 phase float switch wiring diagram is an important component of the electrical system that is used to control liquid levels in a tank. It is a device that detects the level of liquid in the tank and switches on the pump when the level is low and switches off the pump when the level is high. This ensures that the pump operates only when it is needed, conserving electricity and ensuring that the tank does not overflow. In this article, we will discuss everything you need to know about 3 phase float switch wiring diagram.
What is a 3 Phase Float Switch Wiring Diagram?
A 3 phase float switch wiring diagram is a schematic representation of the electrical connections used in a float switch. The float switch is used to control the level of liquid in a tank or vessel. It consists of a float that is attached to a switch, which opens or closes a circuit when the level of liquid in the tank reaches a certain point. The 3 phase float switch wiring diagram shows the electrical connections between the float switch, pump, and power supply.
Components of a Float Switch
A float switch consists of the following components:
| Component | Description |
|---|---|
| Float | A buoyant object that floats on the surface of the liquid in the tank |
| Switch | A device that opens or closes a circuit based on the position of the float |
| Rod | A metal rod that connects the float to the switch |
| Enclosure | A housing that protects the float switch from external factors such as dust, moisture, and vibration |
How Does a 3 Phase Float Switch Wiring Diagram Work?
A 3 phase float switch wiring diagram works by monitoring the level of liquid in a tank and controlling the pump based on that level. When the liquid in the tank is below a certain level, the float switch opens the circuit and turns on the pump. As the liquid level rises, the float rises with it, closing the circuit and turning off the pump when the liquid level reaches a certain point. This cycle repeats as the liquid level in the tank changes.
Types of Float Switches
There are two types of float switches:
- Mechanical float switches: These use a float connected to a switch by a metal rod. When the liquid level rises, the float rises with it, pulling the rod and activating the switch.
- Electronic float switches: These use sensors to detect the level of liquid in the tank. They are more precise than mechanical float switches and are often used in applications where accuracy is critical.
How to Wire a 3 Phase Float Switch?
Wiring a 3 phase float switch is a simple process that involves connecting the switch to the pump and power supply. Here is a step-by-step guide:
Step 1: Gather the Required Tools
You will need the following tools:
- Screwdrivers
- Wire strippers
- Electrical tape
- Wire nuts
Step 2: Turn off the Power Supply
Before you start wiring, make sure to turn off the power supply to the pump and the electrical panel.
Step 3: Connect the Switch to the Pump
Connect the wires from the float switch to the wires from the pump using wire nuts. Make sure to match the colors of the wires.
Step 4: Connect the Switch to the Power Supply
Connect the wires from the float switch to the wires from the power supply using wire nuts. Again, make sure to match the colors of the wires.
Step 5: Test the Float Switch
Turn on the power supply to the pump and the electrical panel. Test the float switch by filling the tank with liquid and observing if the pump turns on and off as the liquid level changes.
