PLATINUM RESISTANCE BULB FOR GENERAL USE
DATA SHEET
FTF
These platinum resistance bulbs are convenient for mea-
suring 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 with-
stand 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.
SPECIFICATIONS
Applicable standard:
JIS C 1604—1997
Resistance element:
Kind of element and nominal resistance
value;
Pt100W
Class;
B class, A class
Prescribed current; 2mA
Temperature accuracy;
Class
Accuracy
A
± (0.15 + 0.002t) °C
B
± (0.3 + 0.005t) °C
Note: (1) t is measuring temperature indi-
cated in °C and unrelated to the +
and – signs.
(2) Accuracy means maximum allow-
able limit when subtracting the
re-sistance value of resistance
element from the temperature in
terms of resistance calculated ac-
cording to the standard resistance
table.
