Gas density transmitter for pressure, temperature and humidity monitoring with Modbus® output GDHT-20
Bika Japan Co., Ltd.
About This Product
■Product description
The model GDHT-20 gas density transmitter is a multi-sensor that measures the pressure, temperature, and humidity of SF6 gas and outputs it digitally. These monitoring parameters are important in SF6 gas quality status monitoring.
■Continuous monitoring
Continuous monitoring of SF6 gas density and humidity are important parameters for stable operation of multiple GIS systems. GDHT-20 measures pressure and temperature, performs calculations against internal data using the built-in microprocessor, and measures the density of SF6 gas. Pressure changes due to heat, but temperature compensation eliminates the influence of heat. GDHT-20 can also measure humidity (dew point) online and manage it in accordance with CIGRE guidelines and IEC standards.
■Modbus® fieldbus
Modbus® RTU uses RS-485 as an interface. A device that supports this fieldbus is required on the receiving side. GDHT-20 can be used not only to measure SF6 gas alone, but also to measure mixed gases with nitrogen gas and CF4 gas. The gas to be measured can be changed by changing the parameters.
■Output signal stability
This model can be used for a long time without maintenance and without recalibration. Since the structure is sealed by welding, there is no deterioration of the seal. Regarding EMC, we comply with IEC61000-4-2 and IEC61000-4-6.
