1. Accurate Detection of High-Temperature Metals: By sensing the infrared energy radiated by metals at high temperatures (usually ≥300℃), it quickly identifies hot metal targets without being affected by metal material or surface conditions (scale, gloss). With a detection response time of ≤10ms, it ensures real-time capture of high-speed moving hot metals.
2. Multiple Signal Output and Control: Supports switching signal output (relay contacts, NPN/PNP level), which can be directly connected to automatic control systems such as PLC and DCS to realize signal feedback of hot metal arrival and departure, meeting industrial needs such as interlock control, counting statistics, and process start-stop; some high-end models support analog output to feed back metal temperature trends.
3. Strong Anti-Interference and Environmental Adaptability: Built-in infrared narrowband filtering technology effectively resists environmental interference such as sunlight, workshop lighting, steam, and dust, with anti-light interference intensity up to 10000Lx or more; protection class ≥IP54, enabling stable operation in harsh industrial environments of -25℃～85℃ and resisting vibration, oil pollution and other working conditions.
4. Self-Inspection and Alarm Functions: Equipped with self-diagnosis capabilities for power supply abnormalities and sensor failures, it indicates equipment status through indicator lights or alarm signal output, facilitating maintenance personnel to troubleshoot problems in a timely manner and ensuring continuous operation of the production line.
5. Flexible Adaptation to Working Conditions: Supports adjustable detection distance (usually 0.1m～10m) to meet the installation needs of different production lines; some models have adjustable detection thresholds, enabling accurate identification of hot metals in different temperature ranges and compatibility with low-speed to high-speed (≤1000m/min) moving metal workpieces.
