Pt100 3-Wire RTD Temperature Sensor Probe
PT100 is a cable-type temperature sensor designed for demanding industrial measurement environments. Its waterproof, oil-resistant and anti-interference design helps maintain dependable temperature sensing where moisture, oil contamination or electrical interference may be present. The sensor uses a three-core PTFE silver-plated lead structure and is suitable for industrial equipment, process temperature measurement and field monitoring applications.
PT100 combines 0.1% measurement accuracy with a response time of ≤0.05s, providing fast and precise feedback when process temperature changes. The Class A resistance element supports dependable temperature measurement, while stability drift of ≤0.04% helps maintain consistent performance during long-term operation. It is suitable for equipment and processes where temperature changes need to be detected quickly and accurately.
PT100 provides a measurement range of -199°C to +200°C and supports multiple probe lengths for different insertion requirements. Available regular probe lengths shown in the supplied material range from 50mm to 500mm, allowing the sensing depth to be selected around different equipment and process points. This flexibility makes the sensor easier to adapt to different temperature measurement installations.
