MBT 5111, Exhaust gas temperature sensors - DANFOSS INDUSTRIAL AUTOMATION

Exhaust gas temperature sensors, such as the Danfoss MBT 5111 series, are precision-engineered devices designed for continuous monitoring of high-temperature exhaust gases in industrial combustion and engine systems. These sensors typically feature a thermocouple or RTD sensing element housed in a robust stainless steel sheath, with a standard probe diameter of 6 mm and lengths ranging from 100 to 500 mm. They are rated for operating temperatures up to 800°C (1472°F) and offer response times as low as 3 seconds in water flow. The MBT 5111 series includes variants with different connection heads (e.g., B, E, or K types) and cable outlets, ensuring compatibility with various control systems. These sensors are also known as exhaust gas temperature probes, EGT sensors, or flue gas temperature transmitters in different markets.

These sensors are primarily deployed in harsh environments where accurate temperature measurement is critical for efficiency and safety. Common applications include marine and stationary diesel engines, gas turbines, industrial boilers, and combined heat and power (CHP) plants. They are installed directly in the exhaust manifold, turbocharger outlet, or flue gas ducts, often in conjunction with engine control units (ECUs) or programmable logic controllers (PLCs) for real-time monitoring and alarm triggering. The sensors are also used in emission monitoring systems to comply with environmental regulations like IMO Tier III or EPA standards.

The Danfoss MBT 5111 series encompasses several subcategories based on probe length, connection type, and output signal. Key article codes include MBT 5111-000-000-000 (standard 100 mm probe, Pt100 RTD, 2-wire), MBT 5111-000-000-100 (200 mm probe, thermocouple type K), and MBT 5111-000-000-200 (300 mm probe, 4-20 mA output). The code structure typically follows the pattern: MBT 5111 - [probe length in mm] - [sensing element type] - [connection variant]. For example, a code ending in -100 indicates a thermocouple type K, while -200 denotes a 4-20 mA transmitter. Other relevant articles include the MBT 5111-000-000-300 (500 mm probe, Pt1000 RTD) and MBT 5111-000-000-400 (with M12 connector).
