Description
Gas density is a crucial operating parameter for high-voltage switchgear. Safe operation of the plant cannot be guaranteed if the required gas density is not present.
The gas density measuring instruments from WIKA warn reliably against dangerously low gas quantities. This is true even under extreme environmental conditions. The switch contacts will switch if the gas density drops as a result of a leakage. The model GDM-100-TI-D Gas Density Monitor output’s high-precision sensors and evaluation electronics are incorporated in addition to the traditional gas density monitor.
GDM-100-TI-D Gas Density Monitor Applications
The GDM-100-TI-D only requires one connection to the measuring point. This is used to determine the pressure, temperature, and gas density.
The pressure related to 20 °C can be read directly on the instrument via the on-site display. Simple switching tasks can be realised quickly and without complication. The integrated Modbus® sensors enable remote monitoring of the plant.
Remote monitoring with Modbus®
The measured data for pressure, temperature, and gas density are transmitted using the standardised Modbus® RTU protocol. The advantages of this digital fieldbus are reduced cabling costs and very detailed measured data.
