NLSW45-3Ex SIL1 (airflow monitor without sensor)

The flow monitor NLSW45-3Ex SIL1 is used with two Z-barriers Gg (included in delivery) and flow sensors F3.*Ex SIL1. Applicable range of the flow sensors: In zone 2 (Gas, Category 3G, EPL Gc) in the explosion groups IIA, IIB, and IIC. 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 NLSW45-3Ex SIL1 must be installed outside of the explosive area.
