The monitor NLSW45-3Ex is used with two Z-barriers (included in delivery) and flow sensors F3.*Ex.The flow sensors can be used as follows: 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 is not 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 must be installed outisde of the explosive area. Power consumption: 4VA Signal output flow: 1x changer Current and contact capacitance: 250VAC, 10A, 2.5kVA Media temperature: -10°C to +75°C Switch-point: adjustable with potentiometer Measurement range: approx. 0.1m/s to 20m/s Cabinet dimensions (LxWxB): 120mmx5mmx73mm Suitable sensors: F3Ex, F3.1Ex, F3.2Ex, F3.3Ex (not included in delivery) |

Product no.: 60620/Ex
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. Power consumption (max.): 5VA/W Signal output flow: 1x changer, 0 - 10 V and 4 - 20mA Current and contact capacitance: 250VAC, 6A, 1,5kVA Media temperature: 0°C to +60°C Switch-point: adjustable via potentiometer Measurement range: approx. 0.5m/s to 20m/s Cabinet dimensions (LxWxB): 112mmx75mmx73mm Suitable sensors: F3Ex, F3.1Ex, F3.2Ex, F3.3Ex (not included in delivery) |
