PT100 & PT1000 RTD Temperature Sensors

Resistance Temperature Detectors (RTDs) are renowned for their high accuracy, excellent stability, and repeatable measurements. Unlike thermocouples, RTDs provide a near-linear response across a wide temperature range, making them ideal for applications where precision is essential. Their durability also ensures long-term reliability, particularly in processes with frequent or small temperature fluctuations.

Yes, RTDs can be designed to withstand demanding conditions. They can be housed in protective sheaths, encased in stainless steel, or fitted with over-braided cables to resist abrasion and mechanical stress.

Standard platinum RTDs, such as Pt100 or Pt1000 sensors, typically operate between -196°C and +600°C, depending on the sensing element and protective materials used. Special designs with high-temperature insulation allow RTDs to be used in more extreme industrial processes, such as furnaces, ovens, and kilns.

Absolutely. RTDs are among the most accurate temperature sensors available. They can be manufactured to meet precise accuracy classes (such as Class A, Class B, or 1/10 DIN), and calibration options, including UKAS-certified or traceable calibration, are available to ensure measurements meet exacting standards.

Choosing the correct RTD depends on several factors: the temperature range, environment, desired accuracy, mounting style, and connection type. Suppliers can advise on the optimal configuration, whether you require a rigid probe, a flexible cable sensor, a duplex design, or custom fittings. Even if you have an existing sensor, RTDs can be adapted or replicated to fit your exact requirements.

Pt100 sensors have a resistance of 100Ω at 0°C, while Pt1000 sensors have 1000Ω at 0°C. Pt1000 sensors are more sensitive and less affected by lead wire resistance, making them ideal for long cable runs, whereas Pt100 is commonly used in standard industrial applications.

Yes. We offer custom wiring, standard or miniature plugs, overbraided cables, and protective sheaths to match your installation needs. Serial numbers or labels can also be added for traceability and asset management.

All our sensors can be supplied with UKAS-accredited or fully traceable calibration certificates. This ensures compliance with industry standards and provides confidence in measurement accuracy.
