High Temperature Glue Level Sensor For Woodworking Edgebanding Machine

Need to read glue level in a CNC edge bander pot without touching the adhesive? The GP-S glue level sensor does it from one small box: a capacitive probe rated to ≤230 °C at the liquid level, an IP65 aluminium control box and a digital display that shows glue volume as a number. Output is a dry contact, NO or NC, with green for output and red for power. It is listed as compatible with all edge banders, works in high viscosity medium such as glue, and packs one piece per carton box.

A glue pot on an edge banding line fails in three ways: it runs dry in the middle of a shift, it gets filled past the mark and cooks a batch of adhesive, and the level control that should prevent both is the one part nobody can read. The GP-S is built for those three failures.

The GP-S is a high temperature glue level sensor for the glue pot of a CNC edge banding machine. It is a capacitive liquid level sensor, specified for high viscosity medium such as glue, and fitted with a digital display that shows glue volume instead of leaving the operator to guess at a sight glass.

Two numbers set the working envelope: a detect liquid level temperature of ≤230 °C and an IP65 enclosure rating on the control box, which is machined from aluminum alloy and supplied in silver. The probe body is steel.

The output is a dry contact, normally open or normally closed, so the machine can be wired to add granulate when the level drops or to stop when it rises. Two lights sit on the box: green for output, red for power. Packing is one piece per carton box. Holding the pot inside a known band is what ends the dry run and the overfill.

What decides whether a level sensor survives a working glue pot:

• No amplifier to adjust — the control box is an adjustment-free glue pot amplifier, so nothing needs trimming after fitting and nothing drifts between shifts.
• Reads the glue, not the air — a capacitive sensor with a ≤230 °C ceiling, specified for high viscosity medium such as glue rather than water.
• Digital display, not a sight glass — glue volume reads as a number, so a new operator can check the pot without opening it.
• Two lights, two facts — green is output and red is power, which separates a sensor fault from a machine that is not calling for glue.
• NO or NC contact — wire the output to fill on a drop or to stop on a rise, matching the logic the machine already uses.
• IP65 control box — an aluminium alloy enclosure in silver keeps dust and glue mist off the electronics, clear of the pot heat.
• Listed for all edge banders — compatibility is stated as all edge banders, so one spare line covers mixed machine brands.
• One piece per carton — each sensor packs individually in a carton box; wholesale orders go into a standard export carton.

The usual choice is to keep running on a sight glass, or to stop the line for a part:

• A dry run stops being a surprise. With glue volume shown as a number, granulate is added before the pot empties, so the shift ends at the same level it started.
• Less adhesive in the bin. A pot filled past the mark cooks a batch; a reading that is visible at a glance removes the guess behind the overfill.
• One spare, every edge bander. The sensor is listed as compatible with all edge banders, so the next machine that needs one takes the same GP-S instead of a different number per brand.
• No setup step afterwards. An adjustment-free amplifier means the job ends at fitting the probe and wiring the contact — there is no pot to trim in.
• Fault-finding from the front panel. Green for output and red for power tells an operator whether the sensor is dead or the machine is not asking for glue, without opening a cabinet.
• Sealed where the heat is. An IP65 aluminium alloy box holds the electronics at a ≤230 °C working ceiling, so dust and glue mist stay outside the part that fails first.

Yes — it is listed as compatible with all edge banders. The GP-S is a glue pot part for CNC edge-banding machines, and it senses glue level rather than edge position or temperature, so the check before ordering is the mounting point on your glue pot, not the machine brand.

≤230 °C at the liquid level. That is the ceiling on the sheet, and it is the number to quote if your pot runs hotter than a standard hot melt setting. Above it, the reading is outside the specified range.

No. It is a capacitive liquid level sensor, so there is no float to stick or sink in thick glue. It is specified for high viscosity medium such as glue, which is exactly the case where a float type loses its travel.

A dry contact, normally open (NO) or normally closed (NC). Wire it to fill on a drop or to stop on a rise, whichever logic your control already expects.

On the digital display on the control box, as glue volume. Two indicator lights back it up: green shows output, red shows power.

No. The control box is an adjustment-free glue pot amplifier, so there is no trimmer to set. Fit the probe, wire the contact, then watch the display with the pot at a known level.

Yes. The medium is specified as high viscosity medium such as glue, and the detection ceiling is ≤230 °C, which covers the glue pot rather than a water tank.
