Features High precision micro-melting sensor technology MODBUS® RTU digital signals or 4…20mA analog signal Protection level IP67 Long-term stability and excellent electromagnetic compatibility Compact design Description The RC580L series gas density sensor is primarily used for continuous monitoring of gas density in high-voltage electrical equipment in transformer substations, helping to prevent system failures and network interruptions in switchgear. This product can also calculate the current gas density by monitoring the pressure and temperature values of the gas. Additionally, the gas density sensor can compensate for pressure changes caused by thermal effects, ensuring that they do not impact the output values. The RC580L series gas density sensor has two output signals: 4…20mA analog signal and RS485 digital signal. It is suitable for any defined gas mixture, including SF6, nitrogen, carbon tetrafluoride, oxygen, carbon dioxide, 3MTM, NovecTM 4710, helium and argon. This product adopts micro-melting pressure sensor technology, with high long-term stability and no requirement of maintenance and re-verification. At the same time, the design of the gas-tight sealing weld and the measurement unit without sealing element is also adopted, which can ensure the permanent sealing of the measurement unit. We can do provide intelligent solutions for both the modernization of existing substations and the construction of new ones.
