What are the types of RTD?

What types of RTDs are available? There are two main types of resistance temperature detectors, thin-film and wire-wound.

What is the difference between Pt100 and PT 1000?

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.

How many types of Pt100 are there?

There are two standards for Pt100 RTDs: the European standard, also known as the DIN or IEC standard, (RTD Temperature vs. Resistance Table) and the American standard (RTD Temperature vs. Resistance Table). The European standard is considered the world-wide standard for platinum RTDs.

What’s the difference between RTD PT100 and Pt1000?

In contrast, a PT1000 sensor, also made of platinum, has a resistance value of 1000 O at 0°C. The RTD Pt100 and Pt1000 are available in a similar range of tolerances, and both can have similar temperature coefficients, depending on the purity of the platinum used in the sensor.

How is the resistance of a RTD measured?

RTDs (Resistance Temperature Detectors) measure temperature-dependent electrical resistance, which increases with rising temperature. This is referred to as a positive temperature coefficient (PTC). The most widely used nominal values are Pt100, Pt500, and Pt1000.

Where do you find the resistance of a Pt1000?

Temperatures in multiples of ten can be found down the left axis, whilst for more precise readings you must move along the horizontal axis between one and nine. For example the resistance of a Pt1000 at 126°C is 1483.30 Ohms. Looking for a Pt100 resistance table?

How are rtd temperature probes used in industry?

Temperature is measured with RTD temperature probes in the food industry, solar and wind energy, HVAC-R and a wide variety of other industrial applications. RTDs (Resistance Temperature Detectors) measure temperature-dependent electrical resistance, which increases with rising temperature.
