The PFGLP22 is a high-precision float level switch designed to ensure reliable liquid level detection in industrial settings. Utilizing the buoyancy principle, the float movement actuates a micro switch via a hermetically sealed stainless steel barrier, providing accurate and maintenance-free operation. No external power is required, making it ideal for hazardous, corrosive, or food-grade environments.
Key Features
- Food-safe, corrosion-resistant stainless steel float and rod
- Hermetically sealed for safe operation in explosive or dusty conditions
- Easy installation without specialized tools
- IP65 rated, ensuring protection against dust and water jets
- SPDT micro switch output with 10A/250V contact capacity
Design & Functionality
Constructed with die-cast aluminum casing and AISI 316 stainless steel components, the PFGLP22 combines durability with high precision. The float operates independently from the rod, allowing intrinsic synchronism for consistent switching, even under turbulent conditions. Its simple yet robust design makes it suitable for diverse industrial liquids, including chemicals, corrosives, and food products.
Total Crossed Beams
The PFGLP22 supports total crossed beams detection, allowing precise monitoring of high and low liquid levels without external adjustments. This feature enhances operational safety, reduces downtime, and prevents overflow or dry-run scenarios.
Beam Pitch Options
With adjustable beam pitch configurations, the PFGLP22 can be customized to meet specific industrial tank requirements. Options include single, double, or multi-point detection, giving operators flexibility in process control.
Intrinsic Synchronism
The PFGLP22 float and micro switch mechanism ensures intrinsic synchronism, providing consistent and reliable signal switching. Its hermetic barrier isolates the float from the micro switch, preventing contamination and ensuring long-term stability.
Operational Advantages
- Maintenance-free operation with no power needed
- High chemical and temperature resistance (-10°C to +100°C)
- ATEX, UKCA, and food contact certified
- Ideal for chemical, food, and beverage industries
