Core Design Advantages (Split-Core Highlights)
Heat and Cold Separation for Extended Lifespan The probe extends directly into the 230°C hot glue pot, while the electronic control box remains externally mounted away from high-temperature sources. This design prevents circuit board aging, drift, or burnout caused by heat, making it ideal for continuous high-temperature operations in woodworking edge banding machines and bookbinding gluing machines.
Digital Precision Sensitivity Adjustment with Anti-Glue Interference Featuring clear digital readouts, the sensor allows fine-tuning of threshold settings to distinguish between pure glue, surface foam, and minor probe residue. This avoids false alarms caused by solidified or clumped hot melt adhesive, and is compatible with both thin hot melt adhesives and high-viscosity PUR polyurethane glues.
No Mechanical Moving Parts—Eliminates Jamming Unlike float-type glue level switches, this sensor has no floating elements or springs. Even when high-temperature glue cools and solidifies, the device won't jam or fail, eliminating the need for frequent cleaning and maintenance.
Standard Industrial Switch Output Supports wide DC voltage input (10–30V) and provides dual NPN/PNP transistor outputs. It can be directly connected to PLCs, audible/visual alarms, or automatic glue refill pumps, enabling real-time glue shortage alerts and automated feeding control.
Stable Performance Against Oil, Grease, and Dust The controller features a metal-sealed housing, and the probe offers IP65 protection, ensuring reliable operation in workshop environments filled with glue fumes, wood chips, and dust.
Mainstream Application Equipment Scenarios
Woodworking Machinery: Level detection of PUR adhesive in automatic edge banding machines, with alarm for adhesive shortage
Printing and Binding: Material level monitoring in glue tanks of Martini perfect binders and bookbinding machines
Hot Melt Adhesive Coating Equipment: High and low adhesive level limit control for adhesive storage tanks in melters and dispensers
Packaging Industry: Material shortage protection in hot melt adhesive laminators to prevent dry-burning of adhesive tanks
