4008400054 Temperature Sensor PT100 7150/E Homag Edgebander Accessories

Need the glue pot on a Homag edgebander to read temperature correctly again? The 4008400054 sensor, also listed as 4-008-40-0054 and referenced as PT100 7150/E, is a platinum resistance thermometer that measures -50 to 700 °C. It seats at the machine's temperature measuring point, connects to the existing control system, and the housing shields the platinum element from dust, moisture and mechanical stress. Both number formats order the same sensor.

Three things go wrong around an edgebander glue pot: the temperature reading drifts and nobody catches it until a band lifts off a panel, a sensor fails on a Friday afternoon and the machine sits idle until a courier arrives, and the parts book prints several numbers for what turns out to be one small probe. The 4008400054 sensor is listed to settle all three.

It is the temperature sensor for Homag edge banding machines, carrying part number 4008400054 or 4-008-40-0054, with the model reference PT100 7150/E. The measuring span is -50 to 700 °C, which is the number to hold against the set point on your pot before you order.

The element is platinum — the resistance thermometer type written in the parts list is PT100. Around it, the housing is designed to keep dust, moisture and mechanical stress away from the element, so the reading holds through a shift instead of wandering as the pot heats and cools.

Fitting is the same two steps as the sensor it replaces: seat it securely at the measuring point the machine designates, then connect it to the control system. A calibration check afterwards confirms the reading; routine maintenance is inspection for wear, damage and contamination, cleaning of the sensor and its connections, and periodic calibration checks.

What decides whether this sensor works on your machine:

• PT100 platinum element — the resistance thermometer type in the parts list, so a calibrated RTD input on the machine sees the element it expects.
• -50 to 700 °C span — one sensor covers the reading from a pot that has not warmed up yet through to a pot at full running temperature.
• Two part numbers, one item — 4008400054 and 4-008-40-0054 are the same sensor, and PT100 7150/E is the model reference on the label.
• Shielded measuring element — the housing is designed to keep dust, moisture and mechanical stress off the platinum element that does the measuring.
• Existing measuring point — the sensor seats where the machine expects its glue pot probe; no adapter, no bracket, no new tapping.
• Wired into your control system — the connection runs to the terminals on the machine diagram, so the value lands where the machine reads it.
• Serviceable in place — inspection, cleaning of the sensor and its connections, and a calibration check are the whole routine.
• Two number formats in your parts list — either format opens the same line on the purchase order, so purchasing stops guessing.
• Durable and precise — the two attributes the parts list gives this sensor, and both trace back to a platinum element inside a housing that keeps the workshop out of it.

The usual choice is a sensor you can fit today or a line that waits on a courier:

• Bond quality you can trace. Adhesion of the edge material to the workpiece depends on what the pot is actually doing; a reading across -50 to 700 °C puts the value inside the range the process runs in instead of leaving it to a hand-held probe.
• One number, no cross-referencing. 4008400054, 4-008-40-0054 and PT100 7150/E all point at the same sensor, so maintenance and purchasing stop ordering around each other.
• Range headroom. A span of -50 to 700 °C means one part covers a cold pot and a hot one, so the high end does not need a second sensor.
• The element stays protected. Dust, moisture and mechanical stress are handled by the housing, and that is where a glue pot sensor quietly loses accuracy over a year of running.
• A maintenance routine that fits a shift. Inspect, clean the sensor and its connections, re-check calibration; nothing on that list requires the pot to come off the machine.
• A spare on the shelf. When the reading dies mid-shift the machine stops with it, so the price of the part is never the real cost of the failure.

Yes, if your glue pot uses the PT100 7150/E sensor. The part is listed for Homag edge banding machines and glue pot spares, under the numbers 4008400054 and 4-008-40-0054. Compare it with the number on the sensor you are pulling out before ordering; a different model number on your machine means a different probe.

Yes. They are two formats of the same number and both order the same PT100 7150/E sensor, so quote whichever format your parts list prints.

-50 to 700 °C. That is the span on the parts list for the PT100 7150/E sensor, which is why the same probe is used where a pot runs hot rather than warm.

A platinum resistance thermometer: the element's resistance changes with temperature and the machine turns that into a reading. The parts list gives the type as PT100 and the sensing element as platinum.

At the temperature measuring point the machine designates, wired into the control system. Seat it securely there, run the connection to the terminals on the machine diagram, then confirm the reading.

Yes — check the calibration rather than assume it. Fit the sensor, run the machine, compare the reading with the pot, and keep periodic calibration checks on the schedule after that.

Inspect, clean and re-check calibration. Look for wear, damage and contamination at every service, clean the sensor and its connections, and hold the calibration check to the same schedule.

The bond goes first. Adhesion of the edge material to the workpiece depends on the temperature the machine is holding, so a wrong reading shows up as open joints and rejected panels before anything alarms.
