PT100 A-class Temperature Sensor 4x30mm Probe w/ 3M Cable - SUS304 Stainless Steel

This sensor meets the Class A (F0.15) tolerance per IEC 60751, meaning its maximum permissible error is ±(0.15 + 0.002*|t|)°C, where 't' is the temperature in °C. This offers higher precision than Class B sensors, making it suitable for applications requiring superior accuracy, such as laboratory calibration and critical process control.

The 4-wire configuration uses two wires for excitation current and two for voltage sensing, which eliminates errors caused by lead wire resistance. Connect the sensor to a compatible 4-wire RTD input module on your PLC or data logger, ensuring correct polarity. Always refer to your instrument's manual for specific wiring diagrams and excitation current settings (typically 0.3-1.0 mA).

The sensor is rated for continuous operation from -50°C to +200°C. The SUS304 stainless steel probe and FEP-insulated cable provide waterproofing and resistance to many chemicals, making it suitable for immersion in liquids, exposure to moist air, and harsh industrial environments. It is also rated for high vibration (40g) and shock (100g) resistance.

Extending the cable is possible but requires careful splicing and shielding to maintain signal integrity and accuracy. It is generally not recommended to cut the cable, as this can compromise the factory calibration and waterproof seals. For best performance, use the provided 3M length or connect it to a properly shielded extension cable designed for RTD signals.
