Platinum Temperature Sensors PT100 & PT1000 by THINKING

Operating Principle of PT100 and PT1000 Sensors

Platinum temperature sensors are based on the physical principle that the electrical resistance of platinum changes in a precise and stable manner depending on temperature.

The following applies:

• PT100 → 100Ω at 0°C
• PT1000 → 1000Ω at 0°C

Thanks to the nearly linear resistance-temperature characteristic of platinum, these sensors enable highly accurate measurements over a wide temperature range.

Advantages of Platinum Sensors Compared to NTC Thermistors

Platinum sensors (PT100/PT1000) offer high measurement accuracy, excellent long-term stability, and nearly linear behavior, which significantly simplifies signal processing. They also provide reliable performance across a wide temperature range.
NTC thermistors, on the other hand, are more cost-effective and offer higher sensitivity within limited temperature ranges, as well as faster response times depending on their design.

Wide Range of Designs for Flexible Integration

The THINKING Electronics portfolio includes a broad selection of mechanical designs and integration options. These include threaded versions such as G1/4” and G1/8” for direct installation, robust stainless steel probe sensors, as well as cable and tube assemblies. For compact applications, epoxy-encapsulated sensor elements are available, while versions with M12 connectors are specifically designed for industrial environments.

Technical Variants and Accuracy Classes

Electrically, the portfolio offers both PT100 and PT1000 variants in accuracy classes A and B. All sensors are based on a standardized temperature coefficient (TCR) of 3850ppm/K, ensuring precise and standardized measurement results.
