Fisher Level Switch 2100/2100E

The Fisher Level Switch 2100/2100E is a reliable, versatile, and cost-effective instrument designed to provide accurate level measurement and control in a variety of process applications. It is primarily used to detect the presence or absence of liquids or solids in tanks, vessels, and other containers, and provides an on/off output signal for process control systems. The 2100/2100E is available in two models: the standard 2100 and the enhanced 2100E, offering additional features for more demanding applications. With its simple yet robust design, the Fisher Level Switch is ideal for use in industries such as chemical processing, water treatment, and oil & gas.
