The main difference between thermocouples and thermal resistors is: 1. The nature of the signal. Thermal resistance itself is a resistor. The change in temperature causes a positive or negative change in resistance. Thermocouples generate changes in induced voltage, which vary with temperature. 2. The temperature ranges detected by the two sensors are different, and the measurement range of the thermocouple is wide. Thermistors are used for low-temperature detection, while thermocouples are typically used for high-temperature detection. From a material perspective, thermistor is a metallic material that is temperature sensitive to changes; Thermocouples are bimetallic materials that represent two different metals. Due to temperature changes, thermal resistors will generate potential differences. What are the differences between thermocouples and thermistors? Although thermistors and thermocouples are not very common in our daily lives, both measuring elements are necessary for temperature measurement and contact measurement. Of course, it is also necessary to understand the differences between the two. Only in this way can the selection of the measurement component be completed. As we are discussing the differences between thermocouples and thermistors, there are some things that can be understood. There are still differences in the properties of signals. One type is that temperature needs to be converted into resistance in order to be measured. After understanding the resistance value, you can obtain the correct temperature data. Thermocouples measure temperature signals by first converting temperature into thermoelectric signals, so the signals they measure themselves need to be different. The materials between them are also different. The current thermal resistance is attributed to metal materials, i.e. temperature changes. Additionally, thermocouples are made of bimetallic materials. Therefore, due to the different metals, they will vary with temperature. This change will also produce certain differences, so there will be certain differences throughout the entire detection temperature range, and the measurement of medium temperature can be completed in different ranges, from which suitable measuring instruments can be selected. Therefore, there is a certain difference between thermistor and thermocouple. For companies that need to use this measurement tool for measurement, they pay attention to the differences between them. Only in this way can we choose the appropriate one. Through these components, measurement components can complete temperature measurements between them and handle measurement issues for large companies. Stainless steel pressure gauges are widely used in industrial applications. They are mainly used to test the pressure in equipment and pipelines. They are easy to install, easy to operate, and cost-effective. They have received high praise from users. Due to users' lack of concern for installation details, measurement accuracy is often low, which is closely related to installation. Below are 11 installation precautions for stainless steel pressure gauges that are prone to correction. 1. Environmental temperature. The ambient temperature for stainless steel pressure gauges is -40 degrees Celsius? 70, relative humidity below 80%. When the temperature deviates from the normal operating temperature of 205, additional temperature errors will be corrected. 2. Protection level. Stainless steel pressure gauges should be installed vertically to maintain the same level as the measuring point. If additional errors caused by excessive liquid column are added, this error does not need to be considered when measuring gas. When installing, please block the explosion-proof port at the back of the calibration cover to avoid affecting the explosion-proof performance. 3. Lower limit range. The measurement range of a normally used stainless steel pressure gauge should not exceed 3/4 of the upper measurement limit under static pressure, and should not exceed 2/3 of the upper measurement limit during fluctuations. Under two pressure conditions, the measured value of high pressure correction shall not be less than one-third of the lower limit. When measuring vacuum degree, please use all vacuum degree components. 4. Loose internal components. When the stainless steel pressure gauge pointer malfunctions, the internal parts become loose or cannot operate normally, please check or have the manufacturer repair it. 5. Maintain balance. Please avoid vibration and conflict of stainless steel pressure gauges to prevent damage. 6. Order introduction. When placing an order, please indicate the purchaser's model and name. The measurement range of the purchaser. The accuracy level of the purchaser does not meet the requirements for correct packaging and other requirements. 7. Fine level. Before installation, please check whether the model, specifications, and accuracy level of the calibrator meet the requirements of the calibrator. Check if the joint screw of the stainless steel pressure gauge is consistent with the internal thread of the device. 8. Angle issue. The pressure calibrator is installed vertically, with an inclination usually below 30 degrees. To avoid display errors, please maintain the same height as the measurement point. 9.0 digits. After installation, do not apply pressure and observe if the pointer is in the 0 position or if it is in contact with the disc stopper. Otherwise, it cannot be used. 10. Equipped with a circular tube. When measuring steam pressure, a circular tube is installed at the lower end of the pressure corrector, and steam pressure is transmitted through intermediate water to allow high-temperature steam to rush into the spring tube without affecting the accuracy of the stainless steel. Steel pressure gauge, or accidentally melting solder to prevent leakage of stainless steel pressure gauge. People who cause accidents or burns. 11. Installation on drum pipelines is prohibited. It is prohibited to install stainless steel pressure gauges directly on the drum, auxiliary cylinder or pipeline. Please connect the water storage pipe (time correction elbow), install a three-way plug valve between the time correction elbow and the pressure correction, and then connect the equipment or pipeline. The function of timing bending is to accumulate condensed water in the steam, in order to prevent steam from directly entering the spring tube and overheating faults. The three-way plug valve is convenient for cleaning pipelines and replacing pressure correctors.
