What is iec 60751?

IEC 60751, 2nd Edition, July 2008 – Industrial platinum resistance thermometers and platinum temperature sensors. This standard specifies requirments for industrial platinum resistance thermometer sensors whose electrical resistance is a defined function of temperature.

What is the most accurate RTD?

The most accurate commercially available class is called 1/10 B (often carrying the older reference of . 01%). The interchangeability typically tightens in practice to . 2°C but only within an abbreviated temperature range, such as 0/50 °C.

How accurate are RTDs?

Accuracy: RTDs are generally more accurate than thermocouples. RTDs have typically an accuracy of 0.1°C, compared to 1°C for most. However, some thermocouple models can match RTD accuracy. The many factors that can affect sensor accuracy include linearity, repeatability or stability.

What is class A tolerance?

Most RTD sensors will use the Class A or Class B designation as set forth in International Standard IEC 751 and will be denoted simply by their temperature deviations at their reference temperature: Class A, with a tolerance of ±0.15°C at 0°C; or Class B, with a tolerance of ±0.3°C at 0°C.

Is Pt100 a thermocouple?

Pt100 thermocouples are a misnomer of two separate types of temperature sensor, a Pt100 resistance thermometer and a thermocouple. Pt100s and thermocouples are two very different technologies both used to measure temperature. A temperature sensor can be one or the other, a sensor cannot be both.

What is the difference between 10K Type 2 and Type 3?

Both BAPI’s 10K-2 and 10K-3 thermistors have 10,000 Ohms of resistance at 77°F. At 32°F (0°C) the 10K-2 thermistor has 32,650 Ohms of resistance and a 10K-3 29,490 Ohms. If a 10K-3 thermistor is substituted for a 10K-2 you could have 6°F of measurement error at 32°F.

What was the purpose of IEC 60751 in 2008?

IEC 60751:2008 specifies the requirements and temperature/resistance relationship for industrial platinum resistance temperature sensors later referred to as “platinum resistors” or “resistors” and industrial platinum resistance thermometers later referred to as “thermometers” whose electrical resistance is a defined function of temperature.

What is IEC 60751, industrial platinum resistance thermometers?

IEC 60751:2008 specifies the requirements and temperature/resistance relationship for industrial platinum resistance temperature sensors later referred to as “”platinum resistors”” or “”resistors”” and industrial platinum resistance thermometers later referred to as “”thermometers”” whose electrical resistance is a defined function of temperature.

What does IEC say about accuracy of RTD?

The IEC therefore states in section 4. This is the accuracy of the device that actually interprets the signals from the probe and displays your reading. Keep in mind that this special selection will generally result in a longer delivery time and higher price tag on the RTD. If playback doesn’t begin shortly, try restarting your device.
