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.
