PLATINUM RESISTANCE BULB FOR GENERAL USE
DATA SHEET
FTF
These platinum resistance bulbs are convenient for measuring a wide range of temperatures in plants and the like.
The resistance element is protected by an internal tube
and moreover by an external tube in order to fully withstand high temperature, high pressure and corrosion.
A contact strip is inserted between the internal and
external protecting tubes, which enables a quick response
and ensures high resistance to vibration.

Note:(1) t is measuring temperature indicated in °C and unrelated to the +
and – signs.
(2) Accuracy means maximum allowable limit when subtracting the
re-sistance value of resistance
element from the temperature in
terms of resistance calculated according to the standard resistance
table.

Note:When the resistance bulb is used at a place of low temperature (below 0 °C) or of high temperature, use a bulb which is filled internally with paraffin or silicon compound after connecting the cable.
Paraffin can be used in a range of 0 to 50 °C and silicon in a range of – 60 to + 150 °C.
