Our capacitance level switches help improve process control, protect equipment, and support safe, efficient operation.
What is a Capacitance Level Switch?
A capacitance level switch is a point-level sensor that detects the presence or absence of a material by measuring changes in capacitance. As the level of liquid or bulk material comes into contact with the probe, the electrical capacitance changes, allowing the device to activate a switching output. Their versatility makes them suitable for many industrial process applications.
How Do They Work?Â
A capacitance point level switch operates by generating an electrical field around its sensing probe. When the probe is surrounded by air, the capacitance remains constant. As the process material reaches the probe, the change in dielectric properties alters the capacitance, triggering the switch.
This simple measuring principle provides dependable point-level detection without moving parts, making a capacitive liquid level switch a robust and low-maintenance solution for process monitoring and control.
