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 |
• 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 |
•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)
•Linear signal

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.
