Endress+Hauser CLS50D-BA1D31 Capacitive Level Switch Reliable Point Level Detection

In process automation, precise and reliable level detection is critical for safety, efficiency, and product quality. The Endress+Hauser CLS50D-BA1D31 stands out as a robust and versatile solution. As part of the proven CLS50 series, this capacitive level switch offers exceptional durability and performance for point-level detection across a wide range of industries, including chemical, food and beverage, water treatment, and pharmaceuticals.

Product Overview

The CLS50D-BA1D31 is a compact, rod-type capacitive sensor. It operates on a simple principle: detecting the change in capacitance between its active electrode and the tank wall when the process media reaches the sensing point. This model features a PEEK (Polyetheretherketone) probe and housing, making it suitable for highly corrosive, abrasive, or hygienic applications. The "BA1D31" suffix indicates specific factory-set parameters, ensuring it is application-optimized for straightforward commissioning.
