Temperature Sensors
Types MBT 5250, MBT 5260 and MBT 5252
Features
Approvals
Heavy-duty temperature sensors
for controlling cooling water, lubrication oil,
hydraulic oil and refrigeration plants within
general industry and marine applications.
These temperature sensors are based
on a standardized Pt 100 or Pt 1000
element, which gives a reliable and accurate
measurement. All three sensor types can be
delivered with NTC / PTC elements on request.
In the low temperature version
(-50 – 200 °C) the measuring insert
is based on a silicone cable, which makes
the sensor very resistant towards vibrations.
The MBT 5250 with changeable measuring
insert and MBT 5260 with xed measuring
insert are equipped with EN 175301-803-A,
Pg 9 as standard. The MBT 5252 is equipped
with a B-head as standard, but can also be
delivered with B-mini Head on request.
If needed, a transmitter (MBT 9110)
can be ordered as an integrated part
of the MBT 5252 sensor.
y Gaseous or liquid media, e.g. air, gas,
vapour, water or oil.
y Up to 200 °C media temperature
(MBT 5250 and MBT 5260)
y Up to 200 °C or 400 °C media temperature
(MBT 5252)
y Pt 100 or Pt 1000 sensing element
y Can be used with 2- or 3-wire connections

The temperature of the transmitter is inuenced by media
temperature, ambient temperature and ventilation in the
engine room. If the temperature of the transmitter exceeds
the max. allowed temperature the transmitter must be
placed in a separated enclosure, as described in the separate
data sheet for MBT 9110.
