VERSAFLOW VORTEX 200
2.7 Surface temperature for equipment protection level Db
For use in areas with combustible dust it should be noted that the indicated maximum surface
temperature of T70°C at an ambient temperature of 65°C / 149°F and a product temperature of
65°C / 149°F is valid without a dust layer.
For higher product temperatures the maximum surface temperature is defined by the product.

Flow sensor circuits
For the compact versions, the intrinsically safe flow sensor circuits are designed as internal circuits.
For the remote versions, the intrinsically safe flow sensor circuits are led through.
The maximum permissible safety values of the flow sensor circuits are listed below:

INFORMATION!
The verification of intrinsic safety for the interconnection between the flow sensor an the signal
converter is not necessary, if the cable length does not exceed 50 m / 164 ft and the supplied
cable is used.
