By far the most common devices used in industry have a nominal resistance of 100 ohms at 0 °C and are called Pt100 sensors ("Pt" is the symbol for platinum, "100" for the resistance in ohms at 0 °C). It is also possible to get Pt1000 sensors, where 1000 is for the resistance in ohms at 0 °C.

The Pt100, which is a Platinum resistance thermometer, is one of the most accurate temperature sensors and is capable of providing excellent stability and repeatability. These sensors are also relatively immune to electrical noise and therefore well suited for temperature measurement in industrial environments, especially around motors ...

了解 PT100 温度传感器的功能和应用。 该产品是工程师和技术人员实现精确温度控制的理想之选。

In fact, the Platinum Resistance Temperature Detector, or RTD Pt100, is used today as an interpolation standard from the oxygen point (-182.96°C) to the antimony point (630.74°C). Platinum is especially suited to this purpose, as it can withstand high temperatures while maintaining excellent stability.

Pt100/Pt1000 resistance thermometers by WIKA. The sensor of a resistance thermometer features a temperature-dependent electrical resistance. This increases with the temperature and is therefore known as a PTC (positive temperature coefficient). With industrial measuring requirements, primarily Pt100 or Pt1000 measuring resistors are used.

2021年9月13日 · In this article, we introduced you to the working principles of the Platinum 100 resistance temperature sensor, its physical properties, and how Pt100 sensors are used in industrial measurement and control systems. We demonstrated the linear relationship between temperature and resistance for platinum.

2024年1月11日 · A PT100 sensor, also known as a platinum resistance temperature detector (RTD), is a type of temperature sensor that utilizes the electrical resistance of platinum to measure temperature accurately. The PT100 designation indicates a platinum sensor with a resistance of 100 ohms at 0 degrees Celsius.

2024年1月20日 · PT100 sensors, also known as platinum resistance thermometers, are widely used in various industries for precise temperature measurement. This comprehensive guide aims to provide an in-depth understanding of PT100 sensors, elucidating their working principle, operation, construction, and diverse applications.

Pt100 electrical resistance temperature sensor - ranging -220 to 750 degrees Celsius.

Pt100 resistance thermometers offer a wide temperature range from -200°C to +850°C and are characterized by their high accuracy. Their resistance-temperature curve is nearly linear, which facilitates calibration and interpretation of measured values.
