1.Function Introduction
As an intelligent instrument designed for modern new energy technology field, new energy temperature and humidity controller can be used to measure oil temperature of the transformer and the temperature and humidity inside the box transformer, indicating visualized and clear temperature and humidity values with Nixie tube. Excessive high ambient temperature will cause the automatic start of the drought fan; Overdue oil temperature calls for the functions of warning output and tripping output; Overdue ambient humidity inside the box transformer will cause automatic start of ambient fan or start of heaters for dehumidification to keep favorable operating environment.
Oil surface temperature sensor adopts armor PT100 oil temperature liquid sensor with three-wire system mode of a connection whose lead wire amounts to 20 meters and temperature shows no distortion. The imported, highly reliable and integrate ambient temperature and humidity sensor enjoys the features of high accuracy, excellent stability and remarkable anti-interference. This controller supports the inquiry of temperature tripping records and RS485 communication or analog quantity output can be selected (4 to 20mA current output or 1 to 5V voltage output).
