Key Benefits

Reliable Detection in Difficult Process Media

Capacitance-based sensing detects the dielectric change when product covers the sensing tip, enabling dependable point level detection in challenging hygienic applications.

Difficult Media Detection

Accurately detects foamy, thick, sticky, and adhesive liquids, even when media builds up on the probe.

Hygienic Construction

Wetted parts made from 316L stainless steel and PEEK support sanitary food and pharmaceutical processes.

Fast Process Response

Reliable switching helps prevent overfill, protect pumps, automate filling, and reduce product loss.

Flexible Installation

Suitable for top, bottom, or side mounting in vessels, tanks, pipelines, and jacketed equipment.

Built for Hygienic Processing

Point-Level Control Where Reliability Matters

These switches identify defined filling levels in vessels and pipelines, then provide control signals for pumps, valves, alarms, and filling systems.

Full and empty detection in vessels and tanks
Pump dry-run and overfill protection
Liquid-presence confirmation in process lines
Automated filling and batch-sequence control
Media-independent operation through change detection

Common Uses

Designed for Sanitary Process Applications

Dependable point-level detection across demanding food, beverage, dairy, brewing, and life-science operations.

Food & Beverage

Detect juices, beverages, sauces, dairy products, and process liquids in tanks and batch systems.

Dairy Processing

Reliable operation with foaming or adhesive media such as milk, cream, whey, yogurt, and cultured products.

Brewing & Fermentation

Stable detection in fermenters and brite tanks, including applications with changing foam conditions.

Pharmaceutical & Life Sciences

Cleanable construction supports bioreactors, buffer tanks, and sterile point-detection applications.

Pipelines & Process Lines

Confirm liquid presence for pump protection, transfer control, and process-flow /no-flow verification.

Filling & Batch Systems

Trigger alarms, valves, and sequence changes at defined full or empty conditions.

Consistent Detection. Hygienic Design.

Anderson-Negele capacitive level switches combine robust 316L stainless-steel and PEEK construction with capacitance-based sensing that remains reliable around foam and product buildup. The result is dependable full and empty detection for process automation, pump protection, and product-loss prevention.
