H2: Pt100-SMD thin film platinum resistor, the performance benchmark for industrial temperature measurement

H3: Wide temperature range coverage, suitable for complex industrial environments

The temperature environment in industrial settings is constantly changing, from low-temperature storage to high-temperature production processes, requiring extremely high temperature adaptability of sensors. The temperature measurement range of Pt100 SMD is -50 ℃~+200 ℃, and some models support special requirements of 0~+150 ℃. It can easily meet the temperature measurement needs of different scenarios such as industrial furnaces, production line equipment, and storage environments, without the need for frequent sensor replacement.

H3: High precision+low drift, reliable and error free data

Industrial production has strict requirements for the accuracy of temperature data. Pt100 SMD follows the DIN EN 60751 standard and is divided into three accuracy levels: A, B, and 2B. The tolerance ranges are ± (0.15+0.002 | t |), ± (0.3+0.005 | t |), and ± (0.6+0.01 | t |), which can accurately capture subtle temperature changes. At the same time, its long-term stability is excellent, with a resistance drift of ≤ 0.06% after 1000 hours at 200 ℃, ensuring reliable data during long-term production and avoiding product defects caused by measurement errors.

Modern industrial production lines are mainly automated, and Pt100 SMD supports various soldering processes such as reflow soldering and wave soldering. It is recommended to use high-temperature solder paste for soldering at 230-240 ℃, which can seamlessly integrate into the automated production process and greatly improve assembly efficiency. Compared to traditional lead type sensors, its SMD packaging design is more convenient for batch installation and reduces labor costs.

The Ro (0 ℃) resistance of Pt100 SMD is 100 Ω, and the temperature coefficient of resistance is 3850ppm/℃. The resistance temperature relationship strictly follows the DIN EN 60751 standard formula. When t ≥ 0 ℃, R (t)=Ro * (1+At+Bt ²) (A=3.9083 × 10 ³ ℃⁻¹, B=-5.775 × 10 ⁻⁷℃⁻²); When t<0 ℃, R (t)=Ro * (1+At+Bt ²+C * (t-100 ℃)) * t ³ (C=-4.183 × 10 ⁻¹² ℃⁻⁴), ensuring measurement accuracy across the entire temperature range.

The component size of Pt100 SMD is only 3.2 × 1.6 × 0.7mm, which is compact and does not occupy too much equipment space, making it easy to integrate into various industrial equipment. The product adopts tin alloy terminals, which have good welding conductivity and high firmness; The packaging is vacuum plastic packaging, which can effectively prevent moisture and oxidation. Each package contains 1000 pieces, with a minimum order quantity of 1000 pieces. It supports customized packaging to meet bulk procurement needs.

H3: Industrial furnace temperature monitoring

Industrial furnaces are the core equipment in industries such as metal processing and ceramic firing, and the uniformity of furnace temperature directly affects product quality. Pt100 SMD is installed at key positions inside the furnace, which can monitor temperature changes in real time. Its wide temperature range and high precision ensure that the furnace temperature is controlled within the set range, reducing product scrap rate. Meanwhile, its excellent long-term stability avoids frequent shutdown calibration and improves production efficiency.

In production lines such as electronic component welding and automotive parts processing, high operating temperatures of equipment may lead to component damage. Pt100 SMD is integrated into the temperature control module of the device, providing real-time feedback on temperature data. When the temperature exceeds the threshold, a cooling mechanism is triggered in a timely manner to ensure the safe operation of the device. Its multiple welding methods are adaptable to the assembly needs of different production lines, with strong compatibility.

For industrial warehouses that require strict temperature control, such as chemical raw materials and electronic component warehouses, Pt100 SMD can accurately monitor the temperature of the storage environment to ensure that materials are not affected by high or low temperatures. Its compact size makes it easy to install on storage shelves, ventilation openings, and other locations. The vacuum packaging design makes it less susceptible to moisture damage in storage environments and has a longer service life.
