PT100 A-class 0.1 Precision Temperature Sensor 4x30mm SUS304 Stainless Steel Probe w/ 0.5m Cable

This sensor meets Class A accuracy per the DIN EN 60751 standard, which corresponds to a tolerance of ±(0.15 + 0.002*|t|)°C. Class A represents the highest standard grade for industrial PT100 sensors, ensuring superior precision suitable for critical measurement and control applications compared to the wider tolerance of Class B sensors.

No, you cannot connect it directly. A PT100 RTD outputs a small change in resistance. You require an external signal conditioning circuit or RTD transmitter module to provide a stable excitation current (0.3-1.0 mA), measure the resistance, and convert it into a standard voltage (0-5V, 0-10V) or digital signal (I2C, RS485) compatible with your microcontroller, PLC, or data acquisition system.

Yes, the SUS304 stainless steel probe body offers good corrosion resistance and is waterproof, making it suitable for immersion in water, oils, and many non-aggressive chemicals. For highly corrosive environments, a probe with PTFE coating or 316L stainless steel housing would be recommended. Always verify chemical compatibility for your specific application.

The specified continuous operating temperature range is -50°C to +200°C. The included cable is 0.5 meters long with FEP insulation and shielding. For longer runs, you can extend the cable, but using high-quality, shielded instrumentation cable is crucial to maintain signal integrity and minimize measurement error caused by lead wire resistance, especially for 2-wire RTD connections.
