WIKA GDxx-20 digital SF6 transmitter

Click2Contact

The WIKA GDxx-20 digital SF₆ transmitter series is able to determine the relative humidity (dewpoint), the pressure, temperature and density of SF₆ gas and SF₆ gas mixtures with enhanced precision in a wide measuring range.

Full transparency of SF₆ gas status helps utilities to boost security and efficiency. The streamlined design with only one process and one cable connection makes for easy implementation into new or existing switchgear possible.

Digital Modbus enables state-of-the-art communications, ready for smart monitoring environments, as well as minimising programming and wiring costs. Up to 247 transmitters can be connected on one bus system. SF₆ gas online monitoring maximises equipment availability, enabling a predictive reliability-centred maintenance strategy.
