Molten Metal Temperature Measurement System

Product Specifications

Technical details and manufacturing context for Molten Metal Temperature Measurement System

Definition

This industrial measurement system is designed for continuous, non-contact temperature monitoring of molten metals in furnaces, ladles, and casting lines. It integrates advanced optical sensors, protective housings, and data processing units to provide real-time temperature data critical for quality control and process optimization. The system withstands harsh industrial environments with high temperatures, dust, and electromagnetic interference, enabling precise thermal management in basic metal manufacturing operations.

The system operates on the principle of infrared pyrometry, detecting thermal radiation emitted by the molten metal surface. It converts this radiation into electrical signals, processes the data through algorithms to calculate accurate temperature readings, and transmits results to control systems. Key specifications include a temperature range of 600–1800 °C, measurement accuracy of ±0.5 °C, response time of 1–5 ms, spectral response of 0.7–1.1 μm, and operating temperature of 0–60 °C. The system offers repeatability of ±0.1% of reading, an analog isolated output signal of 4–20 mA, and requires a 24 V DC supply (24 ±10%). It has an ingress protection rating of IP65 per IEC 60529, optical resolution of 100:1, adjustable emissivity setting from 0.10 to 1.00, ambient humidity range of 0–95% RH (non-condensing), and weight of 2.5–3.5 kg depending on configuration.

Materials used include stainless steel housing, sapphire lens, infrared sensor, ceramic insulation, and copper wiring. The system is intended for use in basic metal manufacturing, where precise temperature control is essential. It is important to verify model-specific values and standards with the legal manufacturer or supplier before procurement or installation. The listed parameters serve as reference ranges and must be confirmed for the actual model and application.

Working Principle

The system uses infrared pyrometry to detect thermal radiation emitted by the molten metal surface. The radiation is captured by a sapphire lens and focused onto an infrared sensor, which converts it into an electrical signal. This signal is processed through algorithms that compensate for emissivity and ambient conditions to calculate accurate temperature readings. The results are transmitted to control systems via a 4–20 mA analog output. The system is designed for continuous operation in harsh environments, with protective housing and ceramic insulation to withstand high temperatures and electromagnetic interference.
