ABB TSP111 temperature sensor

ABB TSP111 temperature sensor

The ABB TSP111 temperature sensor is a practical, cost-effective industrial measurement device belonging to ABB is SensyTemp TSP100 series, specifically engineered for light-to-mid-duty applications where existing thermowells are already in place. Designed to simplify installation and reduce operational costs, it is an ideal choice for independent stations, small-to-mid-sized plants, and large facility auxiliary systems across sectors such as chemical processing, energy production, general process engineering, tank and pipeline construction, and machinery engineering[superscript:1][superscript:2]. The ABB TSP111 temperature sensor features a modular design compliant with DIN 43772 standards, focusing on easy integration with pre-installed thermowells while delivering reliable precision and robust performance—all without unnecessary complexities.

Precision and adaptability are key strengths of the ABB TSP111 temperature sensor, which supports a wide range of measuring elements to suit diverse application needs. For RTD configurations, it accommodates thin-film and wire-wound Pt100, Pt1000, and Cu100 options, complying with IEC 60751 standards[superscript:4]. Thin-film RTDs offer a measurement range of -50°C to +400°C (B grade) and -30°C to +300°C (A grade), while wire-wound Pt100s extend to -200°C to +800°C with AA grade accuracy available for critical applications[superscript:1][superscript:4]. Thermocouple options include K, J, N, E, S, and B types, adhering to IEC 60584 and ANSI MC 96.1 standards; S-type thermocouples cover 0°C to 1600°C for high-heat requirements, with Class I accuracy of ±1.5°C or ±0.004t (whichever is larger)[superscript:1][superscript:4].

A defining characteristic of the ABB TSP111 temperature sensor is its design without a built-in thermowell—it is specifically intended for installation into existing thermowells, which eliminates the need for additional process modifications and reduces installation time and costs[superscript:1][superscript:3][superscript:5]. The replaceable measuring inset (compliant with DIN 43735) allows for on-site element replacement without removing the entire sensor from the existing thermowell, significantly minimizing maintenance downtime[superscript:2][superscript:4]. The measuring inset features a 10mm spring travel on clamping springs, ensuring secure base contact for reliable heat transfer and consistent readings[superscript:4]. Inset outer diameters are available in 3mm, 4.5mm, 6mm, and 8mm (for thermocouples), with tip options including 8mm and 10mm sleeves[superscript:4].

The ABB TSP111 temperature sensor delivers impressive performance metrics tailored to its application scope. It boasts a T90 response time optimized for existing thermowell setups, with vibration resistance exceeding 30 m/sec² (3g) and up to 100 m/sec² (10g) for thin-film RTDs (10-500 Hz), ensuring stability in dynamic industrial environments[superscript:1][superscript:4]. Long-term stability is ±0.1% of full scale per year, reducing calibration frequency and operational costs. Electrical isolation of 2.5 kV AC (60 seconds) between input and output ensures strong anti-interference capabilities, compliant with IEC EN 61326-1 standards[superscript:1]. It operates on a 10.5-45 V DC power supply (when paired with an integrated transmitter) and supports load capacities up to 600Ω.

Built for durability and usability, the ABB TSP111 temperature sensor features a range of connection head options, including BUZ (aluminum, hinged cover), BUZH (aluminum, tall hinged cover), BUZ HD (aluminum, tall cover with LCD), BU KH (polyamide), and BEG (stainless steel)[superscript:2][superscript:3]. Aluminum heads are epoxy-coated for corrosion resistance, while stainless steel heads offer enhanced durability in harsh environments. Ambient operating temperature ranges from -40°C to 130°C (without transmitters) and -40°C to 85°C (with LCD displays), with a storage temperature range of -20°C to 70°C (20-95% non-condensing humidity)[superscript:1][superscript:2]. Maximum process pressure capacity ranges from 40 to 100 bar (580-1450 psi), depending on the existing thermowell material and configuration[superscript:1].

Safety is prioritized, with the ABB TSP111 temperature sensor holding ATEX, IECEx, EAC-Ex (GOST), and NEPSI explosion protection approvals for Zone 1/2 hazardous areas[superscript:1][superscript:2]. Sensors with integrated transmitters are SIL 2 certified (IEC 61508) for safety-critical loops[superscript:1][superscript:3]. Integration options include direct sensor signals, 4-20 mA DC with HART 7, Profibus PA 3.01, and Foundation Fieldbus ITK 5.2, enabling seamless compatibility with existing control systems[superscript:2][superscript:3]. Configuration is straightforward via FDT/DTM tools, EDD, HART handheld terminals, or optional LCD displays, with built-in diagnostics for wire break and sensor fault detection.
