Heating cartridge

Heating cartridge 28V

NEO20X heating cartridges to prevent condensation

The NEO20X heating cartridges are PTC heating elements that are operated with a fixed supply voltage of 5V, 24V or 28V. They are used to heat the sensor and thus prevent condensation of water vapour. These heating cartridges are not required for the actual measurement, but are used in extremely humid measurement environments to prevent the temperature from falling below the dew point.
