ABB TSP311 temperature sensor

ABB TSP311 temperature sensor

The ABB TSP311 temperature sensor is an industrial-grade measurement device belonging to ABB is SensyTemp TSP300 product series, specifically designed with a threaded thermowell to deliver reliable, high-precision temperature data for a wide range of industrial process applications. As a cost-effective and durable solution, it caters to independent stations, small-to-mid-sized plants, and large-scale facilities across sectors such as chemical processing, power generation, water and wastewater treatment, food and beverage, and general manufacturing. The ABB TSP311 temperature sensor features a modular design, combining a replaceable measuring inset, threaded thermowell, extension tube (optional), and connection head, ensuring easy maintenance, flexible configuration, and consistent performance in moderate to harsh industrial environments.

Precision and adaptability are key attributes of the ABB TSP311 temperature sensor, which supports both RTD and thermocouple measuring elements to meet diverse application requirements. For RTD configurations, it accommodates Pt100 (thin-film and wire-wound) and Pt1000, complying with IEC 60751 standards. The Pt100 wire-wound variant offers a measurement range of -200°C to +600°C, while the thin-film Pt100 covers -50°C to +400°C, with accuracy classes available in B, A, and AA grades—AA grade providing the highest precision for critical process control. For thermocouple inputs, the sensor supports K, J, N, E, S, and B types, adhering to IEC 60584 standards, with temperature ranges varying by type: K-type covers -40°C to +1200°C, S-type reaches up to 1600°C, and J-type spans -40°C to +750°C, all with Class I accuracy of ±1.5°C or ±0.004t (whichever is larger)[superscript:4].

A defining feature of the ABB TSP311 temperature sensor is its threaded thermowell, engineered for secure process connection and efficient heat transfer. Thermowell materials include 316L (1.4404) stainless steel as standard, with optional upgrades to 316Ti (1.4571), Inconel 600 (2.4816), and Hastelloy C276 (2.4819) for corrosion-resistant and high-temperature applications. The threaded connection options include ½” NPT, ¾” NPT, M16×1.5, and M20×1.5, with maximum process pressures up to 630 bar (9135 psi) depending on the material, thread size, and operating temperature. The thermowell’s insertion length ranges from 50mm to 500mm (customizable), with a recommended insertion depth of 8-10×thermowell tip diameter for liquid media and 10-15× for gaseous media to ensure accurate temperature detection.

The ABB TSP311 temperature sensor delivers exceptional performance metrics, including an adjustable T90 response time of 600 ms to 2500 ms, customizable based on the thermowell design and application requirements. It boasts long-term stability of ±0.1% of full scale per year, minimizing calibration frequency and reducing maintenance downtime. Electrical performance is enhanced by 2.5 kV AC electrical isolation (for 60 seconds) between input and output, ensuring strong anti-interference capabilities in electrically noisy industrial environments, compliant with IEC EN 61326-1 standards. The sensor’s measuring inset (TSA100 series) features pressure springs for secure base contact, ensuring reliable heat transfer and consistent readings.

Built for durability, the ABB TSP311 temperature sensor features a robust connection head available in epoxy-coated low-copper aluminum (standard) or 316L stainless steel (optional), designed to withstand industrial debris, moisture, and moderate corrosion. Connection head options include AGL (aluminum, screw-on cover), AGS (stainless steel, screw-on cover), and AGD (aluminum with LCD display), all with an IP67 protection rating (NEMA 4X) for dust and water resistance. The ambient operating temperature range is -40°C to +85°C, with a storage temperature range of -50°C to +90°C (20%~95% non-condensing), ensuring consistent performance in extreme weather conditions. The sensor weighs 280g (aluminum housing) to 350g (stainless steel housing), with a compact design that supports unrestricted mounting positions[superscript:1].

For integration and safety, the ABB TSP311 temperature sensor offers flexible output options, including direct sensor signal (RTD/thermocouple) or 4-20 mA DC with HART 7 communication when equipped with an integrated transmitter. It supports electrical isolation of up to 5000 Vrms for 60 seconds, enhancing electrical safety in demanding setups. Safety certifications include SIL 2 (IEC 61508) for sensors with integrated transmitters, along with ATEX, IECEx, and FM/CSA explosion protection approvals for Zone 1/2 hazardous areas, adhering to international防爆 standards[superscript:3][superscript:5]. Installation is simplified with standard threaded connections, and the replaceable measuring inset allows for element replacement without removing the entire sensor from the process, reducing downtime. Configurable via FDT/DTM tools, EDD, or HART handheld terminals (with optional LCD display), it includes built-in diagnostics for wire break and sensor fault detection.

Backed by ABB is global service network and reputation for industrial quality, the ABB TSP311 temperature sensor is a versatile, cost-effective solution that balances precision, durability, and usability. Its modular construction, wide range of configurations, and robust performance make it ideal for general industrial temperature monitoring and critical process control. Whether for moderate or harsh environments, the ABB TSP311 temperature sensor delivers consistent, reliable data, helping businesses optimize processes, reduce operational costs, and ensure safety compliance.
