RS PRO PT100 RTD Sensor 6 mm Diameter, 150 mm Length, 4 Wire, Class B Accuracy, -50°C to 250°C Stainless Steel Probe

RS PRO PT100 RTD Sensor, model PT100, is a high-stability platinum resistance temperature detector designed for demanding industrial, laboratory, and process environments. The sensor utilizes a PT100 element, recognized for its linear and accurate temperature-to-resistance relationship, providing reliable measurement at temperatures ranging from -50°C to 250°C. Its robust construction features a rigid 316 stainless steel sheath that protects the sensing element and ensures long-term corrosion resistance.

The sensor incorporates a four-wire configuration, allowing for precise temperature readings by compensating for lead resistance. This configuration is widely regarded as optimum for accuracy in platinum RTD sensors. The probe diameter is 6 mm and the length is 150 mm, facilitating easy integration into control systems, pipelines, and laboratory setups. Flexible, screened Teflon-insulated leads with a total cable length of 2 meters provide exceptional thermal and electrical insulation, impact resistance, and protection against moisture, corrosion, and harsh chemicals.

The PT100 sensor meets IEC 60751 Class B accuracy standards, ensuring dependable performance in monitoring, control, and automation applications. It is ideal for measuring air, gas, and liquid temperatures in HVAC systems, chemical and plastics processing plants, stoves and grills, food processing facilities, exhaust gas analysis setups, and laboratory equipment.

Installation is straightforward; the sensor's probe is inserted into the measurement environment, and the four wire tails connect to compatible temperature measurement instruments. The sensor’s platinum element exhibits a resistance of 100 ohms at 0°C, which changes linearly with temperature, enabling direct conversion to temperature values using industry-standard algorithms or PT100-compatible equipment.

Applications include HVAC temperature monitoring, industrial process control, laboratory thermal measurement, food process temperature sensing, and chemical temperature analysis. The sensor's screened cable design is tailored to minimize electromagnetic interference, maintaining robust and stable readings even in environments with significant electrical noise.

With its combination of precise sensing, versatile installation dimensions, and durable materials, the RS PRO PT100 RTD Sensor model PT100 is a preferred choice for professionals seeking reliable temperature measurement solutions across various technical sectors.
