Why do we use Pt100?

Platinum 100, or Pt100, resistance temperature detectors are an important part of many process control installations. Accurate and repeatable measurement of temperature is a requirement for many processes, including heating and cooling, chemical reactions, pasteurization, and many others.

What is the difference between PTC and Pt1000?

– PT100 is an RTD (Resistance Temperature Probe) made of Platinum metal which has a resistance value of 100 ohms at zero degrees celsius. – PTC (Positive Temperature Coefficient) and NTC (Negative Temperature Coefficient) are both types of Thermistor. NTC have resistance that decreases with increasing temperature.

What do you mean by Pt100?

Pt100 is a resistance temperature detector, made of material Platinum (= Pt_) and its resistance value at 0 °C temperature is 100 ohm (=_100). Hence the name is Pt100.

Are all Pt100 the same?

Pt100 sensors are available in different accuracy classes. The most common accuracy classes are AA, A, B and C which are defined in the IEC 60751 standard. Standards define a sort of an ideal Pt100 sensor for the manufacturers to aim at.

Are all Pt1000 sensors the same?

There are just a couple of differences between the two types of RTD sensors, the main one being the resistance value at 0°C; 100Ω for a Pt100 and 1000Ω for a Pt1000 but there are others. As well as the base resistance for a Pt1000 being ten times that of a Pt100, so is the fundamental interval.

What is the range of PT100?

PT100 platinum resistance thermometers. Platinum resistance thermometers (PRTs) offer excellent accuracy over a wide temperature range (from –200 to +850 °C). Standard sensors are are available from many manufacturers with various accuracy specifications and numerous packaging options to suit most applications.

Where are PT100 used?

A PT100 is the most common type of Resistance Temperature Detector (RTD). The PT100 has a resistance of 100 Ohms at 0°C and 138.5 Ohms at 100°C. PT100s are a common choice for measuring temperature in industrial processes and laboratories. They are a popular choice due to their stability, accuracy and repeatability.

What is the difference between NTC and PTC probes?

PTC thermistors resistance increases with temperature rising. NTC thermistors resistance decreases with temperature rising. PTC thermistors are made of doped polycrystalline ceramic on the basis of barium titanate, major material BaTio3.
