The sensor communicates the values measured for gas density, temperature and pressure via the LoRaWAN® network protocol. The device also features an alarm function for the three parameters as well as for the battery status that signals, independent of the preset transmission cycle, that a limit value has been reached.
As a compact wireless device, the model GD-20-W is particularly suitable for retrofitting existing installations operated with SF6 gas or alternative insulating gases. The installation and maintenance effort is low. The battery life is over ten years, depending on the measuring and transmission rate.
The sensor calculates gas density from the pressure and temperature values. It measures the pressure at 20 °C with an accuracy of ± 0.2 percent. The device monitors gas density continuously and thus allows demand-driven asset maintenance.
With 11,200 employees, the WIKA Group is a global market leader in pressure and temperature measurement and sets the standard in the measured variables of level, force and flow, and in calibration technology. The broad portfolio of high-precision products, solutions and services makes the family-run business a strong and reliable partner. WIKA’s unique experience and know-how make sensing technology smarter, add more value and prepare it for a sustainable future: This is “Smart in sensing”.
