PT100 Temperature Sensor Stainless Steel Thermocouple with A Grade Imported Chip, 1m Teflon Silver-Plated Shielded Cable, 0.5% Accuracy (Class B)

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 1m Teflon (PTFE) 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 A Grade tolerance is ±(0.15 + 0.002|t|)°C, meaning at 0°C the tolerance is ±0.15°C, and at 100°C it is ±0.35°C . This makes it suitable for applications requiring better precision than standard Class B sensors.

The Teflon silver-plated shielded cable provides excellent resistance to high temperatures and chemicals, and the shielding protects the low-level resistance signal from electromagnetic interference. PTFE insulation retains its properties up to approximately 260°C depending on the specific cable construction . The probe is typically supplied as a 3-wire configuration for this type to compensate for lead resistance .

Critical limitations: If the chip is truly Class A, a 2-wire configuration is not valid for Class A accuracy—the lead resistance uncertainty makes Class A unachievable without 3-wire or 4-wire compensation . Verify the wiring configuration with your supplier. The cable temperature rating (PTFE, ~260°C) limits the practical operating range, even though the Pt100 element itself can handle higher temperatures.

Features
