CEMA CMX17 SERIES

 

 2-wire RTD Temperature Transmitter for Head-mounting Type
● Linearised temperature measurement with PT100 sensor

● To avoid temperature signal attenuation during long  
   distance transmission, it converts PT100 into standard   
   analog current output 4~20 mA DC ( 2 -wire )
   
● A stable and accurate figure can be collected and shown   
   on the display of terminal instrument. The instrument 
   includes PLC, digital display,industrial computer, ect.
