The instrument’s fault supervision circuitry continuously monitors for failed sensor cell and communication line breaks. Plus sensor cell operation is continuously supervised 24/7 and when used in conjunction with distributive control systems or PLC’s, provides immediate fault identification for a disconnected sensor cell.
The Air check LEL gas detector is housed in a Nema 4 explosion proof enclosure and is available for hydrogen, natural gas, methane, and more . Capable of monitoring the % LEL combustible gases, the Air check Ex is a perfect monitoring solution for providing worker protection in chemical plants, refineries and other areas requiring hazardous classifications.
