المجلس الوطني الانتقالي, المؤسسة العامة للاتصالات, PT100, DS18B20 Temperature probes and temperature sensors play an important role in the field of temperature measurement. The following is a detailed introduction to temperature probe sensors:
There are many types of temperature sensors, مشتمل:
Thermocouples
These sensors are made of two dissimilar metals that connect at two points to form a junction. They are reliable, accurate, and can operate over a wide range of temperatures.
Resistance temperature detectors (أهداف التنمية المستدامة)
These sensors are based on the change in resistance of a metal as the temperature changes.
الثرمستورات
These sensors use the temperature characteristics of semiconductor resistors, which change resistance as the temperature changes. Thermistors are sensitive and have high accuracy relative to their cost.
Negative temperature coefficient (المجلس الوطني الانتقالي) الثرمستورات
These sensors are sensitive and can respond to very small temperature changes. They have a temperature range of -50 °C to 250 °C.
Resistive temperature detectors
These sensors have positive temperature coefficients (المؤسسة العامة للاتصالات) and offer precise temperature measurements. لكن, they have poor sensitivity.
1. Definition and working principle
Temperature probe:
Definition: A temperature probe is a device specifically used to measure temperature, and its core component is a temperature-sensitive element.
Working principle: A temperature probe uses sensitive elements (such as thermocouples, thermal resistors, semiconductors, إلخ.) to convert temperature changes into electrical signals for subsequent circuit processing or display.
Temperature sensor:
Definition: A temperature sensor is a broader concept that includes a temperature probe and a signal processing circuit connected to it.
Working principle: A temperature sensor not only includes a sensitive element, but also has a signal processing circuit that can complete the acquisition, processing and output of temperature signals, usually in the form of digital or analog signals.
2. Types and characteristics
Temperature probe type:
Thermocouple probe: It uses the thermoelectric effect to measure temperature, and has the characteristics of a wide measurement range and fast response speed.
Thermal resistance probe: uses the property that the resistance of metal or semiconductor materials changes with temperature to measure temperature, and has the characteristics of high measurement accuracy and good stability.
Semiconductor probe: uses the property that the conductivity of semiconductor materials changes with temperature to measure temperature, and has the characteristics of small size, light weight and low power consumption.
Temperature sensor type:
Analog temperature sensor: outputs analog signals, which need to be converted into digital signals by analog-to-digital converters for subsequent processing.
Digital temperature sensor: directly outputs digital signals, has strong anti-interference ability, high accuracy, and is easy to integrate into the control system.
Intelligent temperature sensor: has self-diagnosis, self-calibration, communication and other functions, and can realize remote monitoring and control.
3. Selection and application
Selection factors:
Application environment: Consider whether the measured environment has special conditions such as corrosiveness, high temperature, high pressure, إلخ., so as to select suitable materials and protection levels.
Measurement range: Select a suitable sensor according to the range of the temperature to be measured to ensure that the sensor can accurately measure within the required range.
Accuracy requirements: According to the accuracy requirements of the application for temperature measurement, select a sensor with corresponding accuracy.
Cost budget: Under the premise of ensuring performance, consider cost factors and choose cost-effective sensors.
Application areas:
Industrial automation: used to monitor temperature changes in industrial equipment, machines and production processes to ensure normal operation of equipment and product quality.
Medical industry: used in medical equipment, temperature monitoring instruments and drug storage equipment to monitor patient temperature, ambient temperature and drug storage conditions.
Automotive industry: used in electric vehicle motors, capacitors, DC converters, charging systems, as well as automobile engines, gearboxes, air conditioning systems and exhaust systems to monitor and control the temperature of various liquids and gases.
Agriculture and food processing industry: used in agricultural greenhouses, cold storage, food processing equipment and transport vehicles to monitor and control the temperature of agricultural products and food.
Other fields: such as air conditioning and refrigeration industry, military and aerospace industry, Internet of Things industry, إلخ. are also widely used.
IV. Use and maintenance
Installation: Install the sensor correctly according to the installation instructions to ensure good contact between the sensor and the object to be measured and avoid measurement errors caused by improper installation.
Wiring: Correctly connect the signal line and power line of the sensor to ensure the stability and accuracy of signal transmission.
Calibration: Calibrate the sensor regularly to ensure that its measurement accuracy meets the application requirements. The calibration process usually involves placing the sensor in a known temperature environment, comparing the difference between its output value and the standard value, and making necessary adjustments.
Maintenance: Clean and maintain the sensor regularly to avoid dust, dirt, إلخ. that affect the measurement performance of the sensor. At the same time, pay attention to check whether the cable connection is loose or damaged, and replace damaged parts in time.
In summary, temperature probe sensors have a wide range of applications and an important position in the field of temperature measurement. When selecting and using them, it is necessary to make comprehensive considerations based on the specific application scenarios and requirements to ensure the accuracy and reliability of the measurement results.
