Application
It is one kind of thermometers to measure middle and low
temperature on the spot. It could be used to directly measure
temperature of liquid, vapor and gas ranging from -80 to 500
.
Features
1.directly display temperature on the spot
2.high reliability and long life expectancy
3.many structure forms to meet different demands
Operation Theory
Bimetallic thermometer is based on bimetal bended into ring
shape. One side of bimetal expands in time of being heated,
which results in revolving of indicator, then the meter indicates
corresponding temperature value to pyroelectric potential.
Main Technical Parameters
1.Executive Standard
JB/T8803-1998
2.Nominal Diameter of Dial: 60, 100, 150
3.Accuracy Class: 1.0 ,1.5
4.Thermal Response Time: 40s
5.Protection Class: IP55
6.Angle-adjusting Error
It shall be no more than 1% of its measuring range
7.Return Error
It shall be no more than the absolute value of basic
error limit.
8.Repeat
The repeat range shall be no more than 1/2 of absolute
value of basic error limit.
