◆Application scope:
AT-WSK-B is mainly used for power equipment (such as outdoor terminal boxes, high and low voltage control cabinets, ring network switchgear, handcart switchgear, underground substations, circuit breaker mechanism boxes, instrument boxes, etc.)
And other related fields that require humidity control and anti condensation. It can be used for a long time in strong electric fields, strong magnetic fields, and various harsh natural environments, effectively preventing various accidents caused by humid environments in power equipment and ensuring the efficient and safe operation of automated operations.◆
working principle:
When the device is in operation, the sensor detects the relative humidity of the surrounding environment and sends the relevant parameters to the subsequent circuit for processing. When there is a possibility of condensation, it drives the next level execution circuit to perform external load heating and ventilation, forcing the medium to be modified to meet standard working conditions until condensation no longer occurs, putting the system back in monitoring mode. This process repeats automatically. This product has two independent humidity monitoring units, which can simultaneously monitor the humidity of two environments or perform dual monitoring on one environment.
