In the world of temperature measurement, high-accuracy thermistors are becoming increasingly vital. These small yet powerful components play a crucial role in ensuring precise temperature control across various industries. At Focusens, we specialize in providing high-accuracy thermistors that offer outstanding performance, reliability, and accuracy for a wide range of applications. What is a Thermistor? A thermistor is a type of resistor whose resistance varies significantly with temperature. The term "thermistor" is derived from the combination of "thermal" and "resistor," reflecting their core function of changing resistance with changes in temperature. Thermistors are commonly used in temperature sensing applications because they offer high sensitivity, quick response times, and a wide range of resistance values. There are two primary types of thermistors: NTC (Negative Temperature Coefficient) and PTC (Positive Temperature Coefficient). The key difference between them is how their resistance changes with temperature. NTC thermistors decrease in resistance as temperature increases, while PTC thermistors increase in resistance with rising temperatures. Why Choose High-Accuracy Thermistors? High-accuracy thermistors are designed to provide precise and reliable temperature readings. The accuracy of a thermistor is essential in many applications, from industrial automation and HVAC systems to medical devices and consumer electronics. Here’s why high-accuracy thermistors are important: Precise Temperature Control: Many systems, especially those in critical industries such as healthcare and aerospace, require precise temperature control. A high-accuracy thermistor ensures that these systems operate efficiently, preventing overheating or undercooling that could lead to equipment failure or safety hazards. Quick Response Time: High-accuracy thermistors typically have fast response times, meaning they can quickly adapt to changes in temperature. This feature is essential for applications where temperature fluctuations need to be detected and managed in real-time. Wide Temperature Range: Many high-accuracy thermistors can function over a broad temperature range, making them versatile and suitable for a variety of environmental conditions. Whether it's for extreme cold or heat, a high-accuracy thermistor can provide reliable temperature readings. Long-Term Stability: For industries that rely on consistent performance over time, high-accuracy thermistors are a dependable choice. They maintain accuracy for extended periods, ensuring reliable data for long-term operations. Applications of High-Accuracy Thermistors High-accuracy thermistors are used in a wide array of industries and applications. Here are some common use cases where Focusens' high-accuracy thermistors play an essential role: Medical Devices: In medical equipment like patient monitoring systems or thermometers, precise temperature measurement is critical. High-accuracy thermistors are used to...

"Welcome to the Focusens website. If you reply to the news, please wear it online and prepare for help." Incoming Material Inspection To ensure that all raw materials meet product specifications and quality standards, our company inspects the batch number, production date, and quality certification documents of the materials. We conduct a visual inspection to ensure that there is no damage, contamination, or deformation. It's important to note that we have standardized control procedures for supplier onboarding and material procurement, along with regular evaluations to enhance the quality assurance of both materials and supplier capabilities. Cable Preparation (Cutting and Stripping Sensor Harness) According to product design requirements, we cut the cables to the appropriate length. Using specialized cutting and stripping equipment and insulation strippers, we cut the cables based on design drawings. Additionally, to enhance signal conductivity and stability, and to improve downstream process performance, we perform tinning on the conductor of the stripped wires when the process requires it. Connecting Components and Lead Wires (Spot Welding/Soldering/Copper Band Crimping) Depending on the product's application and performance needs, we choose the appropriate connection method to securely connect the sensor's sensing elements with the wires. For example, when dealing with thermistors, which are temperature-sensitive resistors, it’s essential to ensure proper connections to maintain accurate temperature readings. Understanding what a thermistor does—primarily acting as a temperature sensor by changing resistance with temperature—helps guide these processes. We use spot welding equipment to connect the components. During soldering, we keep the soldering iron tip clean and control the welding time and temperature to ensure a secure connection without damaging the components. Weld Inspection We inspect the weld points for completeness and uniformity using CCD, magnifying glasses, or visual inspection to ensure there are no cold solder joints, short circuits, or burrs. To ensure weld quality meets standards, weld inspection is treated as an independent process, with 100% of products inspected. It is crucial to verify that connections, especially in thermistors, maintain their integrity to avoid false readings. If you’re wondering how to test a thermistor, it's important to measure its resistance at different temperatures to ensure it performs correctly. Parts Taping and Alignment To facilitate batch packaging operations, we align and tape the semi-finished sensors, ensuring that the final product's appearance and dimensions are consistent. This step is particularly important for thermistors, where precise alignment impacts their accuracy. Encapsulation and Curing Typically, our sensors undergo 2-3 encapsulation processes to ensure sufficient voltage resistance and insulation reliability for each sensor. This is vital for thermistors, as the encapsul...
