Adhesive thermocouple is a sensor used to measure the surface temperature of objects, widely used in industries, scientific research, medical and other fields. It operates based on the thermoelectric effect, using thin sheets made of two different metal materials. One end is in contact with the object being measured to sense temperature, while the other end is connected to a measuring instrument to convert temperature into a voltage signal for measurement.
Introduction to Adhesive Thermocouple Products
Adhesive thermocouple is a sensor used to measure the surface temperature of objects, widely used in industries, scientific research, medical and other fields. It operates based on the thermoelectric effect, using thin sheets made of two different metal materials. One end is in contact with the object being measured to sense temperature, while the other end is connected to a measuring instrument to convert temperature into a voltage signal for measurement.
Product Features
Small size: Adhesive thermocouples are usually small in size, making them easy to install in various small devices, especially when measuring in narrow spaces or irregularly shaped objects.
Fast response speed: Due to the small thermal capacity of thermocouples, they can quickly respond to temperature changes and achieve instantaneous measurement. For example, the response time of a certain adhesive thermocouple on a metal surface (reaching 95% display time) is only 0.4 seconds.
High measurement accuracy: The measurement accuracy of adhesive thermocouples is usually very high, which can meet various high-precision measurement needs. For example, the measurement accuracy of a certain product can reach ± 0.3% ± 1 ℃ when measuring the surface of a 100 ℃ copper plate.
Good reliability: The adhesive thermocouple has a simple structure, high reliability, and can work normally in various harsh environments. It has strong adhesion, and with the use of silicon-based adhesives, it can bond to almost all surfaces except for a small portion that are difficult to bond to.
Good economy: Compared to other temperature sensors, adhesive thermocouples are usually cheaper and help reduce costs. Meanwhile, due to its adhesive nature, it is easy to measure the temperature of fine surfaces and has strong adhesion, making it reusable according to usage conditions.
Application scenarios
In the industrial field, adhesive thermocouples can be used to monitor the temperature of various equipment, pipelines, reactors, etc. in the industrial production process, ensuring the stability of the production process and product quality.
Research experiment: In the laboratory, adhesive thermocouples are commonly used to measure temperature changes under various experimental conditions, providing accurate data support for scientific research.
Medical applications: In the medical field, adhesive thermocouples can be used to monitor patients' body temperature, real-time monitoring of temperature changes during surgery, etc., providing a basis for medical diagnosis and treatment.
Product specifications and models
There are various specifications and models of adhesive thermocouples to choose from, such as ST-50, ST-51, etc. These models may vary in temperature measurement range, accuracy, response time, material, and other aspects. For example, the maximum operating temperature of the ST-50 series thermocouple can reach 300 ℃, and there are two specifications for wire diameter: 50 μ m and 100 μ m. The length can be selected from 100mm, 300mm, and 500mm.
Precautions for use
Choose the appropriate thermocouple type: Select the appropriate thermocouple model based on measurement range, accuracy, response time, and other requirements.
Correct installation: During installation, ensure that the thermocouple is in close contact with the surface of the object to avoid interference with measurement accuracy caused by oil stains, dust, etc.
Avoid interference: During use, avoid external electromagnetic interference or mechanical damage to the thermocouple.
Regular calibration: To ensure measurement accuracy, it is recommended to calibrate thermocouples regularly.
Attention to protection: When used in high temperature or harsh environments, pay attention to appropriate protection of thermocouples to extend their service life.
In summary, adhesive thermocouples are a convenient, fast, and reliable temperature measurement sensor widely used in various fields. By understanding its working principle, application scenarios, selection, and maintenance points, we can better utilize this tool to provide strong support for production, scientific research, and medical activities.
