Level Switches

Level Switches

A liquid level sensor is used to detect the level of liquid in a particular container. A liquid level sensor is essential in the measuring, detecting and monitoring of liquid. But there are other measuring cues for liquid that are also used in various applications. This instrument reacts to changes in liquid level by opening and closing contacts. Also known as float switches, these tools move in the same direction of the liquid level and are commonly used for high level or low level alarms. Liquid level switches are available in a variety of configurations and materials to meet your liquid compatibility needs. Liquid level switches are even available with strobes to bring immediate attention to alarm level conditions. If you have a question about purchasing a liquid level sensor contact a Davis Application Specialist today.
