Data Sheet
Temperature sensor
Type MBT 5111
For measuring exhaust gas in stationary and marine applications
The MBT 5111 is a heavy-duty temperature
sensor that can be used for measuring and
regulating exhaust gas from diesel engines,
turbines and compressors within stationary and
marine applications.
This temperature sensor is based on a type K
thermo couple, which measures temperatures
up to 800 °C. The slim construction gives a
short reaction time of t
= 2 sec. in water.
0.5
All parts in contact with the media are made of
stainless steel AISI 316 Ti. The sensor is
delivered with a 6 m extension cable as
standard.

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