Technical Specifications (Mechanical & Environmental)

Key Features

• Detects Through Walls:​ Can sense water, granules, or powders through glass/plastic vessel walls up to several mm thick (range depends on wall material and dielectric).
• Flush Mountable:​ 4 mm range when installed flush in metal—no reduction factor loss from adjacent metal.
• Sensitivity Trim:​ Integrated potentiometer lets you tune the switching point to ignore the container wall itself.
• Rugged M12 Metal Housing:​ Nickel-plated brass body withstands mechanical stress better than plastic alternatives.

Applications

• Non-Metallic Tank Level:​ Point-level detection of liquids (water, oil, chemicals) in plastic or glass tanks.
• Hopper / Silo Monitoring:​ Detect presence of granulate, powder, or pellets through the bin wall.
• Packaging QA:​ Verify product presence inside blister packs, bottles, or cartons on filling lines.
• Machine Build:​ Web break / material presence detection for paper, film, or non-woven through a guide roller.
