Permanent monitoring
In order to prevent system failures in switchgear and network outages, the permanent monitoring of the gas density is essential.

The model GD-20-W calculates the current gas density from the pressure and temperature using a complex virial equation in the gas density sensor’s powerful microprocessor. Pressure changes resulting from temperature effects will be compensated by this and will not affect the output value.

Signal stability
Due to its high long-term stability, the sensor is maintenancefree and requires no calibration. Due to the hermetically sealed weld seam and a measuring cell design without
sealing elements, the permanent sealing of the measuring cell is ensured.

LoRaWAN^® output signal
This gas density sensor requires no external power supply due to an integrated, easily replaceable battery. By means of the integrated antenna, the sensor reliably transmits the measured values based on the LoRaWAN^® protocol even over long distances.

Integrated alarm function
The independent sensor enables a variety of alarm settings, including alarms at low densities or high temperatures. By setting the measuring frequency higher than the transmission frequency, the sensor can immediately send a warning when a threshold value is reached and does not need to wait for the next scheduled transmission.

If no threshold value warning is triggered, only the last measured values are transmitted in the next transmission period to save energy and bandwidth.
