The BWY2-804 / BWY2-806 Transformer Oil Surface Temperature Controller Type 2 with BL-FC High-Temperature Composite Sensor is designed for oil temperature detection, local indication, alarm control, cooling control and remote monitoring of transformers and other electrical equipment. Based on the composite temperature rise principle, the product can be equipped with 4 to 6 adjustable switches and supports Pt100 signal output or 4-20mA standard current signal output. It is suitable for oil-immersed transformers, substations, power distribution systems and industrial electrical equipment.

The BWY2-804 / BWY2-806 Transformer Oil Surface Temperature Controller Type 2 is designed for oil temperature detection, local indication, alarm control and remote monitoring of transformers and other electrical equipment. The product is designed based on the composite temperature rise principle and provides reliable outdoor protection performance. It can be equipped with 4 to 6 adjustable switches and supports 4-20mA standard current signal output and Pt100 resistance signal output, making it suitable for oil-immersed transformers, substations, power distribution systems and industrial electrical equipment.

The BWR2-04 / BWR2-06 Transformer Winding Temperature Controller Type 2 with BL-F Composite Transmitter is designed for monitoring, indicating, alarming, cooling control and remote signal transmission of oil-immersed transformer winding temperature. Based on the additional temperature rise principle, the product detects transformer top oil temperature and combines it with the additional temperature rise generated by load current to simulate the transformer winding hot-spot temperature. It supports Pt100 signal output or 4-20mA standard signal output and is suitable for power transformers, oil-immersed transformers, substations, power distribution systems and industrial electrical equipment.

BWY-804 / BWY-806 Type 1 oil temperature indicator (OTI) for oil-immersed transformers. Provides local oil temperature indication, cooling control and alarm contacts, with optional Pt100 and 4-20mA outputs. Compare switch count, signal output, capillary length and mounting requirements before ordering.

BWR-04 / BWR-06 Type 1 winding temperature indicator (WTI) for oil-immersed transformers. Uses top-oil temperature and load-current thermal simulation for winding temperature indication, cooling control, alarm and trip functions. Pt100 and 4-20mA outputs depend on the selected model configuration.
