At Focusens, we're not just about providing temperature sensors—we’re about offering solutions that cater to your unique needs. When it comes to temperature measurement, two sensors often come up: RTD sensors and PT1000 sensors. While both do the same job, they have key differences that can impact performance depending on your application. In this article, we’ll walk you through the differences, helping you choose the right sensor for your specific needs.     What is an RTD Sensor?   RTD stands for Resistance Temperature Detector, and it’s a type of sensor that measures temperature by correlating the resistance of a material (usually platinum) with temperature. As the temperature rises, the resistance of the material increases in a predictable, linear way, making RTDs highly accurate, stable, and reliable.   At Focusens, we not only meet standard requirements, we exceed them. We have reliable process capabilities at ultra-low temperatures (as low as -80°C), high waterproof ratings such as IP68, and response times within 10 seconds. With our deep process expertise and flexible customization, we are ready to handle the most demanding application requirements.   What is a PT1000 Sensor?   A PT1000 sensor is a special type of RTD sensor, with the “1000” referring to its resistance of 1000 ohms at 0°C. Compared to the more common PT100 sensor (which has a resistance of 100 ohms), the PT1000 offers better accuracy and stability, especially in environments where signal integrity is critical. This makes the PT1000 ideal for situations that demand precise measurements or need to transmit data over long distances.     Key Differences Between RTD and PT1000 Sensors   Both sensors belong to the same family, but their differences lie in the details that can make a big impact:   1. Resistance Value      PT100: 100 ohms at 0°C      PT1000: 1000 ohms at 0°C (offering more precision)   2. Signal Sensitivity      PT100: While accurate, the lower resistance can make it more sensitive to interference and noise, especially over long distances.      PT1000: The higher resistance gives it a stronger, more stable signal, making it ideal for environments with long signal transmission distances or high electromagnetic interference.     3. Application Scenarios      PT100: Great for less demanding environments or where budget is a factor.      PT1000: Perfect for critical applications like mechanical manufacturing, scientific research(like extreme temperatures or electromagnetic interference).     Why Choose PT1000 Over RTD?   If you’re looking for flexibility, Focusens has you covered. We understand that every project is different, and we offer customized solutions that fit your specific needs, whether it's ultra-low temperatures, waterproof performance, or custom installatio...

At Focusens, we’re more than just a provider of temperature sensors—we’re your trusted partner in ensuring that every measurement is accurate, reliable, and true to the needs of your application. If you're in the world of temperature control, industrial systems, or scientific research, understanding the core of RTD sensors and how they work is essential. In this article, we’ll demystify RTD sensors, explain how they function, and showcase the incredible difference they can make in your work. What Exactly is an RTD Sensor? An RTD—which stands for Resistance Temperature Detector—is a temperature sensor designed to measure temperature by correlating the resistance of its element to the temperature around it. What sets RTDs apart from thermocouples or thermistors is their incredible accuracy, long-term stability, and reliability. That’s why they’re the go-to choice for industries that demand precision—whether it’s in manufacturing, laboratories, or power plants. At the heart of every RTD sensor is a thin wire, usually made from platinum—chosen for its predictable and stable resistance-to-temperature behavior. This means that RTDs are not only accurate but also highly repeatable over time. While platinum is the most popular material for RTDs, other materials like copper or nickel can also be used depending on the application. How Does an RTD Sensor Work? Imagine the delicate dance of atoms inside a material as it heats up. The basic principle behind how an RTD works is surprisingly simple: as temperature rises, so does resistance. The atoms inside the metal vibrate more, which makes it harder for electrical current to pass through—thus increasing the resistance. Here’s how it unfolds: Temperature Affects Resistance: The RTD element (typically platinum) has a set resistance at each temperature. As temperature rises, the resistance increases, because the atoms in the metal vibrate and block the flow of current more. Measuring the Resistance: A current flows through the RTD element, and the resulting voltage drop is measured. This voltage drop is directly tied to the resistance value, which then correlates to temperature. Converting to Temperature: Once the resistance is measured, it’s converted into a temperature reading using a known relationship, like the Callendar-Van Dusen equation or a lookup table. This is where the real magic happens—turning raw electrical data into precise temperature readings. Precision: Thanks to platinum's nearly linear and predictable relationship between resistance and temperature, RTDs provide highly accurate readings, even across a wide range of temperatures. Types of RTD Sensors Just like there’s no one-size-fits-all solution in the world of temperature sensing, RTDs come in different types to suit different needs. Here are the most common varieties: PT100: The most common RTD sensor, with a resistance of 100 ohms at 0°C. PT100 sensors are widely used across industries like manufacturing, research, and heating systems. P...

How to Check a PTC Thermistor: A StepbyStep Guide At Focusens, we understand the importance of reliable temperature sensors, especially PTC temperature sensors like the PTC thermistor. These components are essential in various applications, from motor protection to household appliances. If you're wondering how to check a PTC thermistor, you're in the right place. This article will guide you through the process, ensuring you can determine if your PTC thermistor is functioning correctly.   What is a PTC Thermistor? Before we dive into the checking process, let's briefly explain what a PTC (Positive Temperature Coefficient) thermistor is. A PTC thermistor is a type of resistor that changes its resistance with temperature. When the temperature rises, the resistance increases sharply. This characteristic makes PTC thermistors useful for overcurrent protection and temperature sensing. Tools You Will Need To check a PTC thermistor, you will need the following tools: 1. Multimeter: This device measures electrical resistance and is essential for checking the PTC probe. 2. Soldering Iron: If the thermistor is soldered into a circuit, you may need this to remove it. 3. Heat Source: A heat gun or hot plate will help you test the thermistor's response to temperature changes. 4. Safety Gear: Always wear safety goggles and gloves when handling electrical components. StepbyStep Guide to Checking a PTC Thermistor    1. Power Off the Device   Safety first! Before you begin, make sure the device containing the PTC thermistor is powered off and unplugged. This will prevent any electrical shock or damage during testing.    2. Locate the Thermistor   Find the PTC thermistor on the circuit board. It may have a specific part number or label. Take note of its position, as you will need to refer back to it during the testing process.    3. Disconnect the Thermistor (if Necessary)   If the thermistor is soldered into the circuit, you may need to desolder it for accurate testing. Use a soldering iron to carefully remove it from the circuit. Be cautious not to damage the surrounding components.    4. Set Up Your Multimeter   Turn on the multimeter and set it to measure resistance (ohms). Make sure the probes are connected properly. A multimeter usually has two leads: one for positive and one for negative.    5. Measure Resistance at Room Temperature   Connect the multimeter probes to the thermistor terminals. Make sure you have a good connection. Note the resistance reading at room temperature, which is typically around 20°C to 25°C. A healthy PTC thermistor should show a specific resistance value, which you can find in its datasheet.    6. Apply Heat to the Thermistor   Now it’s time to test the thermistor's response to temperature changes. Use a heat source, such as a heat gun or hot plate, to gently warm the thermistor. Keep the heat source at a safe distance to avoid overheatin...
