NLSW75-AEx (airflow monitor without sensor)

The flow monitor NLSW45-3Ex is used with two Z-barriers (included in delivery) and flow sensors F3.*Ex. Applicable range of the flow sensors: In Zone 2 (Gas, Category 3G, EPL Gc) in the explosion groups IIA, IIB, and IIC. Its unique feature is the analogue signal output. The qualification with regard to the surface temperature is T4; for all gases, vapours and mists with an ignition temperature >135°C the equipment does not present an ignition source. The requirements for simple electrical apparatus according to IEC60079-11, valid for the gas-hazardous area of Zone 1 are met.

The NLSW75-AEx must be installed outside of the explosive area.
