Temperature Sensor – RTD / Thermocouple – (-8 To 1200 °C)
A temperature sensor is a device that measures the temperature of a medium or substance and converts it into an electrical signal that can be read and analyzed by a control system or a data acquisition device. There are various types of temperature sensors available, but two common types used in industrial applications are Resistance Temperature Detectors (RTDs) and Thermocouples. These sensors can measure a wide temperature range, from -8°C to 1200°C, and are suitable for various applications where precise temperature measurement is required.
RTD
RTDs are sensors that use the principle of change in electrical resistance to measure temperature. An RTD consists of a small, thin wire made of a metal, such as platinum or nickel, that is wound around a ceramic or glass core. As the temperature changes, the wire’s resistance changes, which is proportional to the temperature. The RTD sensor is connected to a Wheatstone bridge circuit, which is a type of electrical circuit that can measure small changes in resistance. The output of the Wheatstone bridge is then amplified and processed to provide a temperature reading in degrees Celsius or Fahrenheit. RTDs have several advantages over other temperature sensors. They provide high accuracy and stability, making them suitable for precise temperature measurements. They also have a linear response to temperature changes, which means that the resistance change is proportional to the temperature change, making them easy to calibrate. However, RTDs also have some disadvantages. They are more expensive than other temperature sensors, and their response time is slower, which means they may not be suitable for applications where a quick response is needed.
Thermocouples
Thermocouples are sensors that use the principle of the Seebeck effect to measure temperature. A thermocouple consists of two different types of metals that are joined together at one end. When the temperature at the junction of the two metals changes, a voltage is generated, which is proportional to the temperature difference. The voltage generated by the thermocouple is small, so it needs to be amplified and processed to provide a temperature reading in degrees Celsius or Fahrenheit. Thermocouples have several advantages over other temperature sensors. They are inexpensive, rugged, and can operate in a wide range of temperatures. They also have a fast response time, making them suitable for applications where a quick response is needed. However, thermocouples also have some disadvantages. They provide lower accuracy and stability than other temperature sensors and have a non-linear response to temperature changes, which makes them more challenging to calibrate.
Need for Temperature Sensor – RTD / Thermocouple – (-8 To 1200 °C)
Temperature sensors, such as RTDs and thermocouples, are essential components in the calibration process because they are used to measure the temperature of the medium or substance being tested. NDT techniques, such as ultrasonic testing, eddy current testing, and radiographic testing, rely on precise and accurate temperature measurements to obtain reliable and consistent results. Temperature variations in the test medium or substance can affect the accuracy of the NDT equipment, leading to erroneous readings and inaccurate results. Therefore, temperature sensors are used to monitor and control the temperature of the test medium or substance to ensure that it remains within the required temperature range during the calibration process. RTDs and thermocouples are commonly used in NDT calibration services because they can measure temperatures within a wide range, from -8°C to 1200°C, which is suitable for most NDT applications. They also provide high accuracy and stability, making them ideal for precise temperature measurements. In NDT calibration services, temperature sensors are used to measure the temperature of the calibration blocks, reference standards, and test specimens. The temperature readings are then used to adjust the calibration equipment and compensate for any temperature variations, ensuring that the NDT equipment provides accurate and reliable measurements.
