ABB TSH220 temperature sensor

ABB TSH220 temperature sensor

The ABB TSH220 temperature sensor is an ultra-high-performance high-temperature measurement device belonging to ABB is SensyTemp TSH200 series, specifically engineered to withstand extreme thermal conditions up to 1800°C (3272°F)—making it one of the most robust solutions for the harshest industrial high-heat applications. As a specialized sensor for ultra-high-temperature environments, it caters to independent stations, large-scale industrial facilities, and critical process lines across sectors such as metallurgical smelting, industrial kilns, glass melting, waste incineration, and high-temperature combustion chambers[superscript:3][superscript:4]. The ABB TSH220 temperature sensor features a modular design unique to its ultra-high-temperature capabilities, integrating a straight thermocouple, ceramic thermowell, holding tube (exclusive to TSH220), inner tube, insulating rod, and connection head (with optional integrated transmitter), ensuring reliable performance, easy maintenance, and seamless integration with industrial control systems[superscript:1][superscript:2][superscript:5].

Precision and ultra-high-temperature resilience are the core strengths of the ABB TSH220 temperature sensor, which is optimized exclusively for extreme heat applications with a maximum operating temperature of 1800°C (3272°F)—far exceeding the TSH210’s 1300°C limit[superscript:3][superscript:4]. It uses high-grade thermocouple measuring elements tailored to ultra-high-temperature requirements, supporting types K, N, S, R, and B, all adhering to IEC 60584 and ANSI MC 96.1 standards[superscript:1][superscript:3]. S-type and R-type thermocouples offer the highest temperature capacity, covering 0°C to 1600°C, while B-type extends to 1800°C for the most extreme applications, with Class I accuracy of ±1.5°C or ±0.004t (whichever is larger) to ensure precise temperature detection even in volatile thermal environments. The ABB TSH220 temperature sensor’s T90 response time is optimized for ultra-high-temperature dynamics, ranging from 1000 ms to 3500 ms depending on thermowell design, insertion depth, and process conditions[superscript:2][superscript:3].

A defining and exclusive feature of the ABB TSH220 temperature sensor is its ceramic thermowell, engineered for exceptional thermal stability, resistance to thermal shock, and compatibility with ultra-high temperatures—addressing the key challenge of high-temperature measurement[superscript:3][superscript:4]. Unlike the TSH210’s Inconel thermowell, the TSH220’s ceramic thermowell is purpose-built for temperatures up to 1800°C, with standard material options including alumina (Al₂O₃) and magnesia (MgO) for superior thermal insulation and corrosion resistance in aggressive high-heat media[superscript:2][superscript:4]. The sensor also includes a unique holding tube (exclusive to TSH220) that supports the ceramic thermowell, with flange mounting (DN15 to DN50) as the standard process connection—flanges are welded to the holding tube, which limits installation length per specific parameters[superscript:2]. Threaded socket connections (M20×1.5, ½” NPT) are available as options, with a maximum process pressure capacity of 50 bar (725 psi) at 1000°C, decreasing linearly with increasing temperature due to ceramic material limitations[superscript:2][superscript:4].

The ABB TSH220 temperature sensor delivers exceptional performance metrics tailored to ultra-high-temperature operations. It boasts long-term stability of ±0.2% of full scale per year, minimizing calibration frequency—a critical advantage in hard-to-access ultra-high-temperature installations where maintenance is time-consuming and costly. Electrical isolation of 3.0 kV AC (60 seconds) between input and output ensures strong anti-interference capabilities, compliant with IEC EN 61326-1 standards, even in electrically noisy industrial furnace and kiln environments[superscript:1][superscript:3]. The sensor’s inner tube and insulating rod are manufactured from high-temperature-resistant ceramic materials (alumina or magnesia), ensuring thermal insulation and protecting the thermocouple from harsh process media and extreme heat transfer[superscript:2][superscript:4].

Built for durability in extreme conditions, the ABB TSH220 temperature sensor features a robust connection head available in epoxy-coated die-cast aluminum (standard) or 316L stainless steel (optional)[superscript:4]. Connection head options include AUZ, AUZH, BUZ, and BUZH—all with hinged covers for easy access, rated IP65 (NEMA 4X) for dust and water resistance (aluminum) or IP67 (stainless steel) for harsher, more corrosive environments[superscript:4]. Ambient operating temperature range for the connection head is -40°C to +100°C (without integrated transmitter) and -40°C to +85°C (with transmitter), with a storage temperature range of -50°C to +90°C (20%~95% non-condensing humidity)[superscript:1][superscript:4]. The sensor’s overall length ranges from 300 mm to 1800 mm (customizable based on insertion depth requirements), with installation length parameters: minimum installation length (u_min) = n – k (n = nominal length, k = holding tube length) and maximum installation length (u_max) = n – 50 mm (1.97 in)[superscript:2]. It weighs 2.2 kg (aluminum housing) to 3.8 kg (stainless steel housing), depending on configuration[superscript:4].

For integration and communication, the ABB TSH220 temperature sensor offers flexible options to suit diverse industrial setups. It supports direct thermocouple signal output, as well as 4-20 mA DC with HART 7 communication when equipped with an integrated transmitter[superscript:1][superscript:3][superscript:5]. Optional bus communication protocols include Profibus PA 3.01 and Foundation Fieldbus ITK 5.2, enabling seamless integration with existing industrial control systems and remote monitoring capabilities—critical for ultra-high-temperature applications where on-site monitoring is hazardous[superscript:1][superscript:5]. The sensor operates on a 10.5-45 V DC power supply (when paired with a transmitter), with a load capacity of up to 600Ω (rated load 250Ω)[superscript:1].

Safety is a top priority for the ABB TSH220 temperature sensor, which holds global explosion protection approvals including ATEX, IECEx, FM, and CSA for Zone 1/2 hazardous areas, with a flameproof enclosure and intrinsically safe design to mitigate risks in high-heat, potentially explosive environments[superscript:4]. Sensors equipped with integrated transmitters are SIL 2 certified (IEC 61508) for use in safety-critical ultra-high-temperature loops[superscript:3][superscript:5]. Configuration is straightforward via FDT/DTM tools, EDD, HART handheld terminals, or an optional LCD display (integrated into the connection head), with built-in diagnostics for wire break detection, thermocouple fault monitoring, and overrange alerts—enabling quick troubleshooting without exposing personnel to extreme heat[superscript:1][superscript:5].

Backed by ABB is global service network and reputation for industrial quality, the ABB TSH220 temperature sensor is a specialized, reliable solution for ultra-high-temperature industrial monitoring. Its ceramic thermowell, exclusive holding tube design, precise thermocouple technology, and robust construction make it ideal for extreme heat applications where standard and even other high-temperature sensors fail. Whether for industrial kilns, glass melting, or metallurgical smelting, the ABB TSH220 temperature sensor delivers consistent, accurate data, helping businesses optimize processes, ensure safety compliance, and reduce operational costs.
