FEMA Honeywell EX-DWR6 EX-PRESSURE SWITCH 0 5-6 BAR and Switching differential 0.2bar

• Manufacturer: FEMA

• EX-DWR6

• FEMA Pressure monitor (Ex-d) for hot water, steam, gas, fuel (Ex-DWR)

• FEMA negative pressure switches detect the pressure difference relative to atmospheric pressure. All data relating to the switching pressure ranges and thus also the scale divisions on the switching devices are to be understood as the difference in pressure between the releant atmospheric pressure and the set switching pressure. The "zero" reference point on the scale of the unit corresponds to the relevant atmospheric pressure. Degree of Ex-protection: Ex II 2G Ex d e IIC T6 Gb, Ex II 1/2D Ex ta/tb IIIC T80 °C Da/Db

• Flame proof enclosure Switch components and other electrical functional units capable of igniting explosive gas mixtures are encapsulated in a housing which will survive the

• explosive pressure of an internal explosion and the special design of which prevents the transference of this explosion to the ambient atmosphere.
