Sonda do pomiaru temperatury z czujnikiem rezystancji RTD vs PT100

Czujnik RTD vs PT100: Rezystancja czujnika w sondzie pomiaru temperatury

The main difference between an RTD and a Pt100 is the material used for the sensing element: PT100 is a specific type of RTD thermal resistor, and its name comes fromPlatinum” (platinum) I “100” (100 ohms at 0°C). It is the most commonly used RTD sensor and is widely used in industrial process control, laboratory measurement and other fields that require high-precision temperature monitoring. The advantages of PT100 include:

A PT100 sensor acquires temperature by measuring the change in its electrical resistance, which directly correlates to the temperature it is exposed to; as the temperature increases, the resistance of the platinum element within the sensor also increases, allowing for a precise calculation of the temperature based on this resistance change; essentially, the “100” in PT100 signifies that the sensor has a resistance of 100 ohms at 0°C, and this value changes predictably with temperature fluctuations.

DS18B20 temperature sensor 1-wire waterproof cable + adapter board set

Custom DS18B20 Sensor Probe & 1-Wire Cable Assembly

The DS18B20 sensor communicates using the “1-Drut” protocol, which means it uses a single data line for all communication with a microcontroller, allowing multiple sensors to be connected on the same line and identified by their unique 64-bit serial code; this single data line is pulled high with a resistor and the sensor transmits data by pulling the line low during specific time slots to send bits of information.

Thermistor Temperature Sensor Probe Knowledge Answers

Q: Can you explain sensitivity resolution in more detail? Why are higher values ​​better?
A: High sensitivity eliminates any lead resistance. It also simplifies the supporting electronics. A 10,000 ohm thermistor changes resistance by 4.4% Lub 440 ohms for a 1°C change in temperature. A 100 ohm platinum sensor changes resistance by 1/3 ohm for a 1°C change in temperature.
