Description
The PT100 Temperature Sensor is an industrial-grade Platinum Resistance Temperature Detector (RTD) designed for accurate temperature measurement in liquids, gases, and solid surfaces. It features an imported Pt100 sensing chip housed in a 304 stainless steel sheath with a 0.5m Teflon silver-plated shielded cable for noise immunity in electrically noisy environments.
The probe uses the standard Pt100 element (100Ω at 0°C) and follows the IEC 60751 resistance-temperature curve. The 2B grade tolerance is ±(0.6°C + 1%|t|), meaning at 0°C the tolerance is ±0.6°C, and at 100°C it is approximately ±1.6°C . The 0.5% accuracy figure in your title is consistent with this grade specification .
The Teflon (PTFE) silver-plated shielded cable provides excellent resistance to high temperatures (up to ~180°C), chemicals, and electromagnetic interference . The shielding is particularly important in industrial environments where motors, inverters, and other noise sources can corrupt the low-level resistance signal.
Critical limitations: The 2B grade is a lower-accuracy class—if your application requires better precision, a Class A or Class B probe should be selected instead. The Teflon cable is rated to ~180°C, so the practical temperature range is limited by the cable, not the Pt100 element (which can handle higher temperatures). Do not exceed the cable’s temperature rating.
