Product Description
The PT100 is a widely used, high-precision platinum resistance temperature detector (RTD). The name "PT100" is self-explanatory: "PT" represents the platinum material of its sensitive element, and "100" represents its resistance of 100 ohms (Ω) at 0°C. The PT100 measures temperature by exploiting the highly stable, nearly linear relationship between the resistance of a high-purity platinum wire and temperature. Due to its exceptional accuracy, repeatability, and stability, it is widely considered a benchmark sensor for temperature measurement in the industrial sector.
Specification

Probe Material: Stainless Steel
Sensor Type: -40°C to +125°C
Output Type: RTD (Platinum Resistance Temperature Sensor)
Mounting Type: Insertion
Features
High Accuracy and Stability: Platinum is chemically very stable and resistant to oxidation. Therefore, the PT100 provides highly accurate measurements over a wide temperature range with minimal long-term drift, making its stability far superior to thermocouples and thermistors.
Excellent Linearity: Its resistance-temperature curve is smoother and more linear than that of other temperature sensors (such as NTC thermistors), simplifying signal processing. While not completely linear over a wide temperature range, standard conversion formulas (such as IEC 60751) allow for accurate calculations.
Wide Temperature Range: The standard PT100 has a typical measurement range of -200°C to +850°C, which can be extended with specialized configurations. It excels at precise measurement in low to medium temperatures.
Excellent Interchangeability: PT100s manufactured in accordance with international standards (such as IEC 60751) offer excellent interchangeability, meaning that sensors of the same grade will produce minimal deviation in resistance output at the same temperature, facilitating replacement and repair.
Various structural forms: To adapt to different application scenarios, PT100 has a variety of packaging forms, such as probes with sheaths, surface mount types, thin film types, ceramic packages, etc., with the characteristics of vibration resistance, corrosion resistance, and fast response.
