Working Mechanism

  • Mount the level switch at the desired level in the container or tank.
  • Make sure the float can move up and down as the liquid level changes.
  • As the liquid level rises, the float will also rise, activating the switch mechanism.
  • The switch can be connected to a control system or pump to perform the desired action, such as stopping or starting a process.

Features

Madison Single-Point Liquid Level Switches:

  • These switches are made of polypropylene / 304 stainless steel to ensure long-lasting performance and resistance to corrosion.
  • They have SPST (single pole, single throw) configuration for a simple and reliable circuit configuration.
  • They can handle pressures up to 900 psi and temperatures up to 300 degrees F.

Square D Liquid 2-Level Switches:

  • They can operate effectively within a temperature range of -22 to 220 degrees F.
  • These switches operate on a 'Close On Rise' function, meaning that they close the electrical circuit when the liquid rises to the desired level.
  • They include a stainless steel float, ensuring durability and resistance to corrosion, even in harsh liquid environments.
  • These level switches have the float positioned below the liquid level, enabling them to rise and trigger when the liquid reaches the desired level.

Parker Level Switches:

  • They can withstand temperatures ranging from 0 to 60 degrees C.
  • These switches are extremely sensitive and have built-in springs that can be adjusted to four different levels.

Frequently Asked Questions

What is the difference between a normally open (NO) and normally closed (NC) liquid level switch?

A normally open (NO) liquid level switch stays in the open state when the liquid level is below the set threshold and closes the circuit when the liquid level rises to the desired level. A normally closed (NC) switch operates oppositely, being in a closed state when the liquid level is below the threshold and opening the circuit when the liquid level reaches the set level.

Why do some people use multiple liquid level switches in the same tank?

Utilising multiple liquid level switches in the same tank provides redundancy and more precise level control. They can be wired in parallel or series, depending on the desired functionality.

How do I troubleshoot a liquid level switch that is not functioning properly?

Troubleshooting measures include checking electrical connections, verifying power supply, inspecting for damage or debris affecting switch operation and ensuring proper switch calibration.
