What is the purpose of the transformer used on liquid level controls?

The purpose of the transformer used on liquid level controls is to isolate line voltage potential from ground. This isolation serves several critical functions in electrical systems, particularly in applications involving liquid level controls, where safety and performance are paramount.

By isolating the control circuitry from the main electrical supply, the transformer helps protect sensitive components from high voltage that may be present on the line. This is particularly important in environments where water or other conductive liquids are present, as it reduces the risk of electrical shock to personnel and prevents damage to equipment.

Additionally, this isolation can help prevent electrical noise from the main lines from affecting the operation of the control components, ensuring that level sensing is accurate and reliable. Overall, this isolation feature is key in maintaining operational safety and enhancing the performance of liquid level control systems.
