Temperature sensor
Types MBT 5250, MBT 5260
and MBT 5252
Heavy-duty marine approved temperature sensor.
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.
Features:
• Gaseous or liquid media, e.g. air, gas, vapour,
water or oil
• Up to 200 °C media temperature (MBT 5250
and MBT 5260)
• Up to 200 °C or 400 °C media temperature
(MBT 5252)
• Pt 100 or Pt 1000 sensing element
• Can be used with 2 or 3 wire connections
• Gold plated male and female connector (MBT
5250 and MBT 5260)
• MBT 5250 and MBT 5252 with
interchangeable measuring insert
• MBT 5260 with xed measuring insert
• Available with built-in transmitter (MBT 5252)
