When it comes to precise temperature measurement, T-type thermocouples are a reliable choice. At Focusens, we specialize in high-quality T-type thermocouples, designed for a wide range of applications. This article will explain what a T-type thermocouple is, how it works, and where it is typically used. What is a T-Type Thermocouple? A T-type thermocouple is a type of temperature sensor that measures temperature based on the voltage generated when two different metals are joined together. The “T” in T-type thermocouple refers to the materials used: copper and constantan. Copper is one of the most commonly used metals in thermocouples due to its high conductivity, while constantan is a copper-nickel alloy known for its stable resistance-temperature relationship. The T-type thermocouple generates a voltage that is proportional to the temperature difference between the two junctions (the measuring junction and the reference junction). This voltage can then be measured and converted into a temperature reading. How Does a T-Type Thermocouple Work? The operation of a T-type thermocouple is based on the Seebeck effect. This effect occurs when two dissimilar metals are connected at two different temperatures. The junction at the hotter end of the T-type thermocouple generates a voltage, and this voltage is directly related to the temperature difference between the two junctions. The voltage generated by the T-type thermocouple is very small, requiring precise instruments to measure and convert this voltage into a meaningful temperature reading. The voltage produced by a T-type thermocouple is typically in the range of a few millivolts, and this voltage is then correlated to a specific temperature value using calibration data. Benefits of T-Type Thermocouples T-type thermocouples offer several advantages that make them ideal for specific temperature sensing applications. Here are some of the key benefits: High Accuracy: T-type thermocouples are known for their excellent accuracy and precision in temperature measurement. They provide reliable and consistent temperature readings, making them ideal for applications where precision is critical. Wide Temperature Range: T-type thermocouples can measure temperatures in the range of -200°C to +350°C. While this is not as broad as some other thermocouple types (such as K-type thermocouples), it is well-suited for low-temperature applications. This range makes them particularly useful for cryogenic and laboratory applications. Good Stability: The materials used in T-type thermocouples—copper and constantan—are known for their excellent stability over time. This means T-type thermocouples can provide accurate measurements for extended periods, making them ideal for long-term use in stable environments. Cost-Effective: T-type thermocouples are relatively inexpensive compared to other temperature sensors, such as RTDs or infrared sensors. Their low cost makes them an attractive option for many applications where budge...

In today’s tech-savvy world, magnetic switches are quietly at the core of many devices we use every day—whether it's the door of your house, the car you're driving, or the machinery in factories. With their non-contact, reliable operation and long lifespan, these switches are essential in keeping things running smoothly. At Focusens, we offer a variety of magnetic switches tailored for different industries, ensuring quality and precision. Let’s explore how they work, their types, and where they make a real impact. How Do Magnetic Switches Work? Magnetic switches work by using the power of a magnetic field to control electrical circuits. Unlike traditional switches that need physical contact, magnetic switches offer a non-contact solution, making them more durable and reliable. At the heart of many of these switches is the reed switch—a simple, yet ingenious component. Imagine two tiny metal reeds inside a glass tube. When a magnet gets close, the reeds pull together, closing the circuit and allowing current to flow. When the magnet moves away, the reeds spring apart, opening the circuit and cutting off the current. This effortless, non-contact mechanism ensures a long-lasting performance, free from mechanical wear. Types of Magnetic Switches There’s no one-size-fits-all solution in the world of switches. That’s why magnetic switches come in a variety of types: Normally Open (NO) The switch remains open until a magnet is nearby, completing the circuit. Think of it as your door switch in a security system—activated when needed. Normally Closed (NC) In this setup, the circuit is normally closed, and it only opens when a magnet triggers it. It’s often used in alarms that go off when a door or window opens unexpectedly. NO-NC Changeover Type This versatile type can toggle between open and closed states depending on the presence of a magnetic field, ideal for complex systems like industrial automation. Where Are Magnetic Switches Used? The beauty of magnetic switches lies in their versatility. They can be found in many different environments, helping to make processes smoother and safer. Home Security In home security, these switches detect if doors or windows are open or closed. The moment a magnet door switch is triggered, it sets off an alarm, ensuring your home is protected—no wires needed. Automotive Systems In your car, magnetic switches help monitor the door status, warning you if it’s not properly closed. They also play a role in seat occupancy detection, adjusting airbag deployment for safety. Industrial Automation Magnetic switches are key in industries like manufacturing, helping machines know the exact position of mechanical parts. This precision helps streamline production and ensures quality. Why Magnetic Switches Are a Game Changer Here’s why magnetic switches are a must-have for so many applications: Non-Contact Operation They don’t touch anything, so there’s no wear and tear. This makes them more durable and reliable, especially in har...

RTD sensors, or Resistance Temperature Detectors, are widely used for measuring temperature due to their accuracy and reliability. These sensors operate on the principle that the resistance of certain metals, typically platinum, changes with temperature. The PT1000 sensor is a popular type of RTD sensor, and it operates based on the same fundamental principle. Here’s how RTD sensors, like the PT1000 sensor, measure temperature based on changes in resistance: 1. Understanding the PT1000 Sensor The "PT" in PT1000 refers to platinum, the material commonly used for the RTD element. The number "1000" signifies that the sensor has a resistance of 1000 ohms at 0°C, the reference temperature. The PT1000 sensor typically consists of a thin wire or a film of platinum wrapped around a ceramic core. Platinum is chosen due to its near-linear and repeatable change in resistance with temperature, making it ideal for accurate temperature measurement. RTD sensor manufacturers often favor platinum for its reliability in various industries. 2. Principle of Operation: Resistance and Temperature RTD sensors, like the PT1000 sensor, function based on the relationship between temperature and resistance. Platinum, like most metals, has a positive temperature coefficient (PTC), meaning its resistance increases as the temperature rises. For a PT1000 sensor, the resistance increases by approximately 3.85 ohms per degree Celsius. If the temperature increases by 1°C, the sensor's resistance increases by 3.85 ohms. This predictable, near-linear relationship makes the PT1000 a reliable choice for precise temperature measurements, which is why RTD suppliers value this sensor type for their product portfolios. 3. Measuring Resistance to Determine Temperature To measure temperature using a PT1000 sensor, an electrical circuit measures the resistance of the sensor. Typically, a Wheatstone bridge or a 4-wire measurement method is used for greater accuracy. Here’s how the process works: · Current is passed through the RTD sensor: A known current is applied to the RTD sensor, and the voltage drop across the sensor is measured. · Resistance is calculated: Using Ohm’s Law (V = IR), the resistance of the PT1000 sensor is calculated based on the measured voltage and the known current. · Temperature is calculated: The resistance value is compared to a pre-established temperature-resistance curve for platinum, providing an accurate temperature reading. 4. Standard Temperature-Resistance Relationship for PT1000 There are two typically TCR（temperature coefficient of resistance）of PT1000/PT100 ,that is 3850 ppm/K and 3750 ppm/K, Focusens mainly use the one with 3850. Our PT1000 sensor follows a specific standard for resistance values at different temperatures. TCR = 106. (R100– R0)/ 100 · R0  [ppm/K] For example: · At 0°C, the PT1000 has a resistance of 1000 ohms. ·&nbs...
