Exhaust gas temperature sensor MBT 5114

MBT 5114 is a series of exhaust gas temperature sensors used for performance optimization and environmental impact control of large 4 stroke engines.

By utilizing RTD sensing elements the MBT 5114 provides a modern and total cost attractive alternative to the thermo couple exhaust gas sensors.

Features

Approvals

• For measuring exhaust gas in stationary and marine: – diesel and gas engines – turbines – compressors

• Up to 600 °C media temperature (peak 700 °C)

• Fixed or adjustable insertion length

Lloyds Register of Shipping, LR Germanischer Lloyd, GL Det Norske Veritas, DNV Registro Italiano Navara, RINA

• 1 or 2 Pt 1000 elements

• No need for special compensation cable.

• Less noise sensitive

• No cold junction compensation

• Resistant to moisture (works from day one)

• No polarity on the cable (easy to install)

Mounting

The free insertion length may not exceed 25 × sensor diameter, e.g. 150 mm with a 6 mm sensor diameter.

However, it is generally recommended that the sensor is supported close to the tip either by the mounting hole or by a sensor pocket. The sensor might break in case it is mounted without a proper support in a vibrating application like exhaust gas monitoring.

The free insertion length is defined as the part of the outermost sensor end that is not supported by a pocket or a drilled hole in the machinery.

The free length of the cable must be supported for every ½ meter (= 100 × cable diameter).

Especially for turbo inlet/outlet applications it is necessary to mount the sensor in a pocket to prevent sensor damage due to high media velocity and vibrations.
