Basic technical data
Sensing element
Range of working temperatures
The reference voltage at 0 ° C
Thermocouple type K
-200 to 1200 °C *
0,00 mV
* The real range of working temperatures of sensor is defined by the design and technology
Principle
Due to changes in temperature measured environment is defined by the change in voltage measuring
thermocouple. Change in voltage is defined according to EN 60584-1:
n
U = ∑ ai (t90)i
µV
in the range –270°C až 0 °C
i=1
