Molten Steel Temperature Measurement Methods Compared: Handheld vs Infrared vs Wireless Large-Display Thermometer
Product Overview: CYY-W660 Wireless Large-Display Molten Steel Thermometer
The CYY-W660 Wireless Large-Display Molten Steel Temperature Measuring Instrument is a high-precision specialized instrument developed for rapid temperature measurement of molten metal in the smelting and casting industries. When used together with the W330 portable thermometer (with wireless transmission), measurement data is transmitted in real time over long distances directly to a large-screen display.
Built around a high-performance single-chip microcontroller, the instrument incorporates precision-grade sensor components and multiple intelligent processing technologies to ensure long-term stable operation. Wireless transmission technology synchronizes temperature values from the handheld thermometer to the wall-mounted large display with precision, eliminating cable constraints and significantly enhancing anti-interference capability.
Why Accurate Furnace-Front Temperature Measurement Matters
In metallurgy and casting, temperature control during furnace-front metal melting is a decisive factor in product quality. Accurate temperature measurement not only improves production efficiency but also effectively reduces scrap rates and energy costs. Smelting and casting enterprises commonly face the following problems:
Unstable temperature control — temperature deviation directly affects metal quality, mechanical properties, and product pass rate
Inefficient manual recording — traditional methods cannot share data in real time, lowering management efficiency
High production losses — incorrect temperature judgment leads to scrap, rework, and material waste
Poor equipment anti-interference — commercial instruments in complex induction furnace environments often produce errors or failures
High safety risk — on-site wired equipment involves inconvenient cable harnesses
Difficult quality traceability — lack of data recording and historical query functions
Cost pressure — rising energy and material costs demand more precise control
Common Temperature Measurement Methods Compared
Method 1: Traditional Handheld Thermometer
Advantages
Relatively low cost
Simple operation, easy to learn
Disadvantages
High precision but single functionality (limited to local reading; no centralized data sharing)
Method 2: Portable Infrared Thermometer (Pyrometer)
Advantages
Non-contact measurement, convenient to use
Fast measurement, short response time
Disadvantages
Measurement accuracy is heavily affected by environmental conditions such as smoke, dust, and slag- Cannot measure beneath the molten metal surface — only surface temperature is captured
Not suitable for accurate internal temperature measurement of high-temperature molten metal
Method 3: Wireless Large-Display Molten Steel Thermometer (CYY-W660)
Advantages
Wireless long-distance transmission — measurement data is transmitted in real time to the large-screen display, removing traditional cable constraints and improving on-site flexibility and safety
High-precision rapid measurement — high-performance microcontroller and precision sensor deliver a response time of approximately 1 second, resolution of 1 °C, and accuracy of ≤ ±0.2% ±1 °C
Extra-large visible display — 5-inch high-brightness digital tube display with character height of 120 mm, clearly readable from over ten meters away — ideal for shop floor collaboration
Multi-alarm smart functions — broken thermocouple alert, over-range alert, low-voltage alert, plus audible and visual alerts, enhancing production safety
Strong anti-interference capability — professional wireless data module and anti-interference technology allow measurement while the induction furnace is operating — no power interruption required
Data storage & management — stores over 1,000 historical records, supports keypad query and optional automatic printing for quality traceability and production management
Multi-thermocouple compatibility — supports multiple thermocouple types with measurement range up to 2,000 °C
Modular design — the system consists of a wireless handheld thermometer and a large-screen receiver, easy to install and maintain
