Temperature Probe

А “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 (РТС), and thermistors, each with distinct characteristics and applications based on the required accuracy, temperature range, and response time needed for a specific situation.

‌Definition‌: Температурна сонда е уред кој се користи за мерење на температурата, обично се состои од чувствителен елемент и мерно коло. Чувствителниот елемент може да биде термоспој (pt100, pt1000), термички отпорник (ntc, ptc), полупроводник (DS18B20 дигитален), итн., кој може да ги претвори температурните промени во електрични сигнали. Потоа се засилува, филтрирани, претворена, и обработени од мерното коло, и на крај излегува електричен сигнал пропорционален на температурата.
‌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, термички отпорници, полупроводници, итн. 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, итн. 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, добра стабилност, and strong anti-interference ability. Semiconductor probes use semiconductors as sensitive elements, and have the characteristics of small size, light weight, 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, металургијата, електрична енергија, pharmaceutical, food and other industries.
