Dry Type Temperature Indicators

BWDK-3207a 3208 series Dry Type Temperature Indicators are designed and produced according to the national standard JB/T7631.It is smart meter that applicable to measure and control 3 phase winding temperature of dry type transformers,also,it has function to start and stop the cooling fan automatically,alarming for over temperature and breakdown,and communication port connection.

Features:
1.All computing digits calibrated automatically
2.Watchdog sofeware,anti-interference and high reliability
3.Record function for temperature of power-off and past highest temperature
4.3 phase temperature displayed on the same screen
5.Standard mounting structure
