ABB TSP331 temperature sensor

ABB TSP331 temperature sensor

The ABB TSP331 temperature sensor is a high-precision industrial measurement device engineered to deliver accurate, stable temperature data for a wide range of critical process applications, making it an ideal choice for independent stations and large-scale industrial facilities. As a trusted model in ABB’s temperature sensor lineup, it combines robust construction with advanced sensing technology, ensuring reliable performance in harsh and demanding environments. The ABB TSP331 temperature sensor supports multiple sensor types, catering to diverse industrial needs from basic ambient temperature tracking to high-precision process control in sectors such as oil and gas, chemical processing, power generation, and pharmaceutical manufacturing.

Precision is a core advantage of the ABB TSP331 temperature sensor, which boasts a base accuracy of ±0.2% of full scale for standard configurations, with an optional high-accuracy version reaching ±0.1% for applications requiring ultra-tight tolerances. It supports both RTD and thermocouple sensing elements: RTD options include Pt100, Pt1000, and Cu100, with temperature measurement ranges from -200℃ to +500℃ for Pt100 (A级 and B级 accuracy), and -50℃ to +100℃ for Cu100 with an allowable deviation of ±(0.30+0.006t)[superscript:3]. For thermocouple inputs, it accommodates J, K, T, E, N, S, and B types, with temperature ranges varying by type—for example, K-type thermocouples cover -40℃ to +1200℃ with Class I accuracy of ±1.5℃ or ±0.004t (whichever is larger)[superscript:3].

The ABB TSP331 temperature sensor features an adjustable T90 response time, ranging from 500 ms to 2000 ms, allowing customization based on the speed of temperature changes in specific applications. It offers exceptional long-term stability of ±0.1% of full scale per year, minimizing the need for frequent calibration 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.

Built for durability and resilience, the ABB TSP331 temperature sensor features a rugged housing available in epoxy-coated die-cast aluminum or AISI 316L stainless steel, providing robust protection against corrosion, industrial debris, and moisture. It boasts an IP67 protection rating (NEMA 4X), making it suitable for both indoor cabinet mounting and outdoor field installations in harsh conditions. The sensor’s operating ambient temperature range is -40℃ to +85℃, with a storage temperature range of -50℃ to +90℃ (20%~95% non-condensing), ensuring consistent performance in extreme weather or temperature-fluctuating facilities. It weighs 320g and features a compact design with 2×M20×1.5 or 2×½ in NPT electrical connections, supporting unrestricted mounting positions for easy installation.

The ABB TSP331 temperature sensor offers flexible output options to seamlessly integrate with existing industrial control systems, including a standard 4-20 mA DC output with HART 7 communication, and optional Profibus PA or Foundation Fieldbus protocols. It operates on a 10.5-45 V DC power supply, with a load capacity of up to 600Ω (rated load 250Ω). Safety is prioritized, with the sensor holding SIL 2 certification (IEC 61508) for use in safety-critical loops, and optional ATEX, IECEx, and FM/CSA explosion protection approvals for Zone 1/2 hazardous areas—ideal for high-risk industries handling flammable or explosive materials. It also features built-in isolation voltage of up to 5000 Vrms for 60 seconds, enhancing electrical safety in demanding setups.

Usability is simplified with intuitive configuration options, including FDT/DTM tools, EDD, HART handheld terminals, or an optional LCD display with operating buttons for on-site setup and troubleshooting. Built-in diagnostic features include wire break detection, overrange alerts, and sensor fault monitoring (compliant with NAMUR NE 89 and NE 107), enabling quick status checks and minimizing downtime. Backed by ABB’s global service network and reputation for quality, the ABB TSP331 temperature sensor is a versatile, cost-effective solution that delivers consistent, precise temperature monitoring. Its combination of advanced technology, durable design, and flexible integration makes it the perfect choice for modern industrial temperature measurement needs.
