MTR09 Surface Mount RTD Assembly Weld-pad Mounting MIEPL
                     MTR09 SURFACE MOUNT RTD ASSEMBLY
Weld-pad Mounting
MIEPL Make RTD MTR09 acc ura te ly  sense  
temperature with an excellent degree of repeatability  
and interchange ability of elements. The RTD is  
composed of certain metallic elements whose change  
in resistance is a function of temperature. This type of 
 RTDs are used to measure surface temperature . A  
pad is avaible to sensing temperature.
