Sondy temperatury, Typy czujników temperatury & aplikacje
Sonda temperatury to urządzenie używane do pomiaru temperatury, zwykle składający się z czułego elementu i obwodu pomiarowego. Wrażliwy element może być termoparą (PT100, PT1000), rezystor termiczny (NTC, PTC), półprzewodnik (DS18B20 Digital), itp., które mogą przekształcić zmiany temperatury w sygnały elektryczne. Następnie jest wzmacniany, przefiltrowany, Przekształcony, i przetworzone przez obwód pomiarowy, i na koniec sygnał elektryczny proporcjonalny do temperatury jest wyjściowy.
Temperature probes and temperature sensors are two different devices, and they have their own characteristics and application scenarios in measuring temperature.
Temperature Probe
A “temperature probe” is a sensor used to measure temperature by converting the heat energy into a measurable electrical signal, and the most common types of temperature sensors within a probe include thermocouples, Resistance Temperature Detectors (BRT), and thermistors, each with distinct characteristics and applications based on the required accuracy, zakres temperatur, and response time needed for a specific situation.
Definition: Sonda temperatury to urządzenie używane do pomiaru temperatury, zwykle składający się z czułego elementu i obwodu pomiarowego. Wrażliwy element może być termoparą (PT100, PT1000), rezystor termiczny (NTC, PTC), półprzewodnik (DS18B20 Digital), itp., które mogą przekształcić zmiany temperatury w sygnały elektryczne. Następnie jest wzmacniany, przefiltrowany, Przekształcony, i przetworzone przez obwód pomiarowy, i na koniec sygnał elektryczny proporcjonalny do temperatury jest wyjściowy.
Working Principle: The working principle of the temperature probe is to use the response of the sensitive element to temperature changes to convert temperature changes into electrical signals. Common sensitive elements include thermocouples, Rezystory termiczne, półprzewodniki, itp. The working principle of the thermocouple is to use the thermoelectric effect of two different metals or alloys. When they are connected together and at different temperatures, an electromotive force proportional to the temperature is generated. The working principle of the thermal resistor is to use the property that the resistance of metal or semiconductor materials changes with temperature. When the temperature changes, the resistance value will also change accordingly. The working principle of semiconductor is to use the property that the conductivity of semiconductor material changes with temperature. When the temperature changes, the conductivity will also change accordingly.
Type: The types of temperature probes mainly include thermocouple probes, thermal resistor probes, semiconductor probes, itp. Thermocouple probes use thermocouples as sensitive elements, and have the characteristics of wide measurement range, fast response speed, and high precision. Thermal resistor probes use thermal resistors as sensitive elements, and have the characteristics of high measurement accuracy, good stability, and strong anti-interference ability. Semiconductor probes use semiconductors as sensitive elements, and have the characteristics of small size, lekka waga, and low power consumption.
Application fields: Temperature probes are widely used in industry, scientific research, medical care, environmental protection and other fields. Such as temperature measurement and control in chemical, petroleum, metallurgy, electricity, pharmaceutical, food and other industries.
