SF6 AIR SENSOR
For monitoring the air of SF6 indoor plant in permanent operation
The device even detects smallest SF6 concentrations and displays the current measuring values permanently. For the operating personnel it is absolutely necessary to know that no radioactive source is used. Therefore no special measures must be taken during operation.
The SF6 Air Sensor guarantees a quick reaction time. Furthermore, there is no cross sensitivity to moisture and unaffected by background contamination and the measuring result remains constant. Parameters for warning messages and alarm tripping are freely configurable.
Measuring range: 0 to 1,500 ppmv SF6
High longtime stability
No maintenance and consumables are required
Indication of the measuring value via LCD on the front of the device
Air pressure compensated
Analogous and serial interface
The device can only be used together with the SF6 Network Monitor. It cannot be operated autonomously.
