Is IEC 60751?
The international standard IEC 60751 specifies the requirements and temperature/resistance relationship for industrial platinum temperature sensors. The standard was revised by the IEC in 2008 – a revision that can still cause confusion about which tolerance classes are currently valid.
What is din IEC 60751?
This standard, DIN/IEC 60751 (or simply IEC751), requires the RTD to have an electrical resistance of 100.00 Ω at 0°C and a temperature coefficient of resistance (TCR) of 0.00385 Ω/Ω/°C between 0 and 100°C. temperature curve from -200 to 850°C with resistance values given for every degree Celsius.
What is Pt100 sensor?
Pt100 sensors are the most common type of platinum resistance thermometer. Pt refers to that the sensor is made from Platinum (Pt). 100 refers to that at 0°C sensor has a resistance of 100 ohms (Ω). A resistance thermometer is a type of temperature sensor.
What is Pt100 and PT1000?
The RTD PT100, which is the most commonly used RTD sensor, is made of platinum (PT), and its resistance value at 0°C is 100 O. In contrast, a PT1000 sensor, also made of platinum, has a resistance value of 1000 O at 0°C.
What is the difference between thermocouple and Pt100?
Sensitivity: While both sensor types respond quickly to temperature changes, thermocouples are faster. A grounded thermocouple will respond nearly three times faster than a PT100 RTD. The fastest-possible temperature sensor is an exposed tip thermocouple. Accuracy: RTDs are generally more accurate than thermocouples.
What is RTD PT 100?
RTDs – or Resistance Temperature Detectors – are temperature sensors that contain a resistor that changes resistance value as its temperature changes. The pt100 is one of the most accurate temperature sensors. Not only does it provide good accuracy, it also provides excellent stability and repeatability.
Is Pt1000 better than Pt100?
The main difference between Pt100s and Pt1000s in general is the electrical resistance at 0⁰C, which is the number in the name: a Pt100 is 100Ω at 0⁰C and a Pt1000 is 1000Ω at ⁰C. This makes Pt1000s more accurate for small temperature changes as they would result in larger changes in resistance when compared to Pt100s.
