All description
Manufacturer: Pepperl+Fuchs
Description:

The Float Switch from Pepperl+Fuchs is specifically engineered for level detection in liquids, making it an essential component in various industrial applications. With its unique design, which incorporates a mercury switch element, this device ensures precise monitoring of fluid levels, contributing to the safety and efficiency of processes in potentially hazardous locations.

One of the standout features of this float switch is its small diameter sleeve design, enabling easy installation through standard G1 tap holes. This feature is particularly advantageous in tight spaces where traditional switches may not fit. Additionally, the high buoyancy of the ball design enhances the switch’s sensitivity, allowing it to respond effectively to changes in fluid levels. The Float Switch is ideally suited for applications in chemical processing, water treatment, and oil and gas industries, where reliable and safe fluid level monitoring is critical.
