The level of molten and liquefied glass in the furnace is measured with a high-precision laser distance sensor.
Even in the harsh measurement environment of ultra-high temperature molten liquid at 1500°C, it is possible to achieve a measurement error of ±1mm by placing the laser distance sensor at a distance.
Our company does not handle dedicated sensors for specific applications and has only dealt with laser distance measuring sensors. To date, we have been involved in various fields such as civil engineering (measuring internal displacement in tunnels), steel and heavy industries (cranes, boring machines, etc.), woodworking and metal processing machines, monitoring, automated warehouses, and manufacturing process lines. We have received numerous requests asking, "Can sensors be used for this application?" and have worked together with customers to devise solutions, successfully measuring in many applications. Here, I would like to introduce one specific example. This is a measurement method to maintain a constant level of molten and liquefied glass inside a furnace. The level of the molten material in the furnace must not exceed a specified level, and the lower limit must be maintained at a stable level of -15 mm. Even in the harsh measurement environment of ultra-high temperature molten material at 1500°C, by placing the laser distance sensor at a distance, we achieved a measurement error of ±1 mm, and the measurement position could be visually confirmed using visible red laser light, enabling level measurement inside the glass melting furnace.
