BWY-804 series transformer oil temperature indicator Introduction: The BWY-804 series transformer oil temperature indicator (hereinafter referred to as the BWY-804 series OTI) consists of elastic elements, capillaries, bulbs, and miniature conversion bulbs. The volume of temperature sensitive media in the bulbs will change while the thermal bulb senses the temperature. Therefore, the volume increment is transmitted from the capillary to the elastic components, resulting in displacement that can indicate the measured temperature and drive the microswitch to operate, thereby enabling or disabling the cooling transformer system. The BWY-804 series OTI is suitable for measuring and controlling large and medium-sized oil temperature transformers, with excellent protection performance and can achieve 24-hour uninterrupted operation. The BWY-804 series OTI has 4 sets of control switches (which can be expanded to a maximum of 6 switches), and the transformer cooling system has an over temperature alarm and over temperature trip; At the same time as on-site indication, the product can output PT100 platinum resistor and DC (4-20) mA current signal synchronously. These signals are transmitted to the XMT-288FC series digital display indicator or DWBS series temperature transmitter for intelligent unmanned management.
