Laser temperature gun for glass

Out on the line, seconds and degrees decide whether you ship glass or scrap it. A tempering furnace ramp that misses the setpoint, a bending station that drifts off the profile, a lamination press that runs hot on the edges and cool in the middle—those aren’t little hiccups. They eat glass, stall the cell, and force rework you can’t afford. We built a laser temperature gun for glass to catch those losses where they start. What matters under the hood We run near-infrared (NIR) emitters tuned to glass emissivity, so you get a tight spot reading that sees surface temperature clean—even through coatings. The response is sub-second, so you catch transients during ramp-up and soak, not after the whole batch is done. The unit outputs 4–20 mA and RS485, ready to tie straight into PLC and furnace controls. The housing is IP65-rated, so it holds up to dust, mist, and washdown. You can power it from 24 VDC or 230 VAC, and the optics are aligned for a 100:1 distance-to-spot ratio. That lets you measure from a fixed bracket, safely, without contact. Why this tool earns its keep on the floor In hot bending, you need uniform heat along the mold line to avoid optical distortion and spring-back. In tempering, the quench depends on repeatable preheat; if preheat is uneven, thermal stress shows up fast and you get breakage. In EVA/SGP/PVB lamination and coating drying, the cure window is tight—too cool and adhesion falls short, too hot and you get bubbles, haze, or edge seal failure. With this gun, you see those zones in real time, so you can trim burner output, adjust dwell, and keep the profile inside tolerance. The payoff is fewer rejects, steadier cycles, and energy draw that behaves predictably. A few shop-floor notes Installation is straightforward, but alignment is the make-or-break detail. Mount the sensor on a rigid bracket, set the focal distance once, and verify with a blackbody or a certified surface reference. Keep windows clean and pick the right emissivity setting for coated glass—otherwise the readings will drift on you. In high-convection areas, shield the optics from direct airflow so you don’t chase false swings. This is line-of-sight, period: if the path is blocked, measurement stops, so plan the sightline during machine layout.
