Electronic thermo-controllers series

BWDK-5000 thermo-controllers for dry-type transformer series, idesigned and manufactured by standards of < electronic thermo-controller for transformer> JB/T7631-2005, is a new generation of Intelligent Instrumentation for ensuing the safe operation of dry-type transformers.

Controller use three (or four)ф3 the Pt100 platinum resistance as temperature sensor, embedded platinum resistance within the low-voltage winding by the transformer factory. It results in platinum resistance synchronous changes when transformer winding temperature increase, the thermo-controllers will show the three-phase winding temperature (room temperature or cores) on same screen for different platinum-resistance after dealed with by computer itself, meanwhile completed various alarm, control and signal output.

Controller send temperature data and parameters to the remote computer to form Distributed Control System through the analog output or RS232C. RS485 communications, the thermo-control device with communications function match control software of the Windows version for the convenience of user.
