Description

This sensor utilizes a platinum resistance temperature detector (RTD) element, where the electrical resistance changes predictably with temperature. The 4-wire configuration minimizes lead wire resistance errors, enabling highly accurate measurements suitable for precision industrial and laboratory applications. The sensing element is housed within a hermetically sealed SUS304 stainless steel sheath, providing excellent corrosion resistance and mechanical protection.

The sensor is engineered for stability in demanding conditions, featuring high insulation resistance (>100 MΩ at 20°C) and low self-heating effects. Its fast response time in both air and liquid media makes it ideal for dynamic temperature monitoring in processes, HVAC systems, and liquid bath applications. The FEP-insulated and shielded cable ensures signal integrity in electrically noisy environments.

Key Features

  • High-precision platinum RTD (PT100) sensing element with a nominal resistance of 100Ω at 0°C.
  • Compliant with IEC/DIN EN 60751 standard, available in Class A accuracy grade.
  • Durable SUS304 stainless steel probe construction for long-term reliability in corrosive or wet conditions.
  • 4-wire measurement technique for superior accuracy by eliminating lead resistance errors.
  • Rugged, shielded FEP cable provides waterproofing, flexibility, and EMI/RFI protection.
  • Excellent vibration (40g) and shock (100g) resistance for industrial and automotive applications.
  • Wide operational range from -50°C to +200°C with a temperature coefficient of 3850 ppm/K.
  • Optimized performance-to-cost ratio for high-value temperature sensing solutions.

Applications

  • Precision temperature monitoring in industrial process control and automation systems.
  • Liquid temperature measurement in chemical processing, HVAC, and water treatment plants.

Frequently Asked Questions

What is the difference between Class A and Class B accuracy for this PT100 sensor?

Class A accuracy, as specified by IEC 60751, offers a tighter tolerance (F0.15, ±(0.15 + 0.002*|t|)°C) compared to Class B (F0.30). This sensor is Class A, providing higher precision for critical measurement applications like laboratory calibration or process control where minimal error is required across its -50°C to +200°C range.

How do I connect this 4-wire PT100 sensor to my data acquisition system or PLC?

The 4-wire configuration uses two wires for excitation current and two for voltage sensing, effectively eliminating errors caused by lead wire resistance. You must connect it to a compatible 4-wire RTD input module on your PLC or DAQ system. Ensure the measuring current is within the specified 0.3–1.0 mA range to avoid self-heating errors.

Is this sensor suitable for immersion in liquids or corrosive environments?

Yes, the hermetically sealed SUS304 stainless steel probe body provides excellent corrosion resistance and is waterproof, making it suitable for direct immersion in non-aggressive liquids like water, oils, or mild chemicals. For highly corrosive media, verify the chemical compatibility of SUS304 stainless steel with your specific application.

What is the purpose of the shielded cable, and how should it be terminated?

The stainless steel braided shield within the FEP cable protects the low-level sensor signal from electromagnetic interference (EMI) and radio-frequency interference (RFI). For optimal performance, the shield should be properly grounded at the measurement instrument or controller end, while leaving the sensor end unconnected to prevent ground loops.
