The SIS Sanitary Intelligent Level Switch is a hygienic level detection solution designed for modern industrial process automation. Built for food processing, beverage manufacturing, pharmaceutical production, and sanitary chemical applications, this intelligent sensor provides accurate single-point level monitoring in tanks and pipelines.
Using advanced frequency sweep sensing technology, the sensor detects changes in resonance when materials contact the probe. This enables highly reliable switching signals for high-level alarms, low-level alarms, and pump dry-run protection. Its hygienic stainless-steel construction and compact form factor make it ideal for installations where space, cleanliness, and operational reliability are critical.
The device is engineered for sanitary environments and supports CIP (Clean-In-Place) and SIP (Sterilize-In-Place) cleaning systems, ensuring compliance with strict hygiene standards across food and pharmaceutical industries.

Design & Functionality
The SIS intelligent level switch is engineered for durability, hygiene, and high-performance detection. Its stainless-steel body and sanitary probe design allow safe use in food-grade processing systems.
The sensing probe emits an electrical signal that scans across a frequency spectrum. When the probe contacts a material, the medium creates a unique resonance pattern. The device analyzes this resonance change and immediately triggers a switching output. This intelligent detection principle ensures stable performance even in challenging materials such as viscous liquids, foam, paste, or powder.
The compact sensor body allows installation in narrow pipelines, small process vessels, or difficult mounting positions commonly found in industrial facilities.
Total Crossed Beams
The intelligent sensing technology ensures consistent detection across multiple material types. It effectively identifies liquid presence, viscous coatings, foam layers, and powder deposits without false triggering caused by buildup or residue.
Beam Pitch Options
The sensor supports different probe lengths and installation types including standard, extension, mini, and rear-mount configurations. This flexibility allows integration into tanks, process vessels, and pipeline systems with varying installation requirements.
Intrinsic Synchronism
Advanced electronic circuitry ensures synchronized signal processing between the sensing probe and control output. This intrinsic synchronism improves switching accuracy, reduces signal noise, and enhances overall measurement reliability across different media types.
Operational Advantages
The SIS sanitary intelligent level switch improves industrial process reliability by delivering fast switching response and stable level monitoring. Its intelligent detection technology minimizes maintenance requirements and prevents false alarms caused by foam, viscosity, or sediment buildup.
With hygienic materials, compact construction, and advanced sensing capabilities, the device provides an ideal solution for automated level detection in sanitary production environments such as food processing plants, beverage facilities, pharmaceutical manufacturing lines, and hygienic chemical processing systems.
