data sheet 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. applicable standard: jis c 16041997 resistance element: kind of element and nominal resistance value; pt100 w 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 C signs.
