INNO fibre optic temperature sensors ,temperature monitoring systems.
The temperature controller for dry-type transformers is an intelligent controller designed specifically for the safe operation of dry-type transformers. The temperature controller adopts microcontroller technology and uses the platinum thermistor embedded in the dry-type transformer winding to detect and display the temperature rise of the transformer winding. It can automatically start and stop the cooling fan to force air cooling of the winding, avoiding or reducing faults caused by high temperature in the transformer. It can also control the output of over temperature alarm and over temperature trip to ensure that the transformer operates in a safe state, thereby extending the working life of the transformer.

Example: BWDK-PQ201F, PQ represents the extended embedded temperature control box, 2 represents the AC220V working power supply, and 3 represents the AC380V working power supply, F represents function code (RS485 communication)
The function codes can be combined according to the requirements, in the order of E F、G、I、L、H、C、TH， If it only contains L H. C. TH function, D needs to be added before the code name.
If there are other special technical or functional requirements, such as Ethernet communication Profibus communication, multi-channel temperature measurement, fiber optic temperature measurement, etc. can all be contacted with us.
