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.
