Continuous monitoring of the hot metal temperature is one key to produce high-grade metal castings with efficient utilisation of energy and raw materials. With the aim of achieving reliable and accurate hot metal temperature detection and control in metallurgical melting furnaces, especially in small-to-medium sized foundries, BFI developed an optical temperature measuring system based on manual lances.

Optical melt temperature measurement independent of emissivity provides

• Continuous measurement of melt temperature
• Fast response time by optical measurement
• No influence by melt bath surface or slag cover
• Precise temperature control to attain desired target temperature
• Avoiding of excessive overheating of melt
• Measurement during heating operation, because insensitive against electromagnetic fields

Technical data of mobile, lance based optical temperature measurement system DynTemp® H:

• Temperature measurement range: 1250°C to 1800°C
• Reproducibility of detector: ± 0,1% + 1 K
• Response time: 0,5 s
• Device dimensions: 0,8 m x 0,8 m x 0,35 m
