Mechanical level indicator type FSA-W
Measurement range 250mbar
For unpressurized tanks containing liquid operating media in dry and protected rooms (measuring accuracy: ± 2%),
Operating media: Waste oil, diesel fuel, FAME, urea solution (AdBlue®), heating oil, organic heating oil, vegetable oil, rainwater, and other water-polluting, non-flammable liquids.
Function: The tank content is determined by measuring the filling level using the float principle. The FSA-W 4-20 mA converts the measurement result into a current signal and passes it on to the SmartBox® digital display device using a cable. On the scale of the mechanical level indicator type FSA-W 4-20 mA, the tank contents can be read continuously in centimeters as the filling height.
Technical data:
-
Extension of the probe cable up to a maximum of 100 m
-
Measuring range: 0 to 2.40 m tank height
-
Tank connection: G 1 1/2
-
Protection class: IP30
-
Connection cable: 10 m
-
Diameter float type FSA-W 4-20 mA: 38 mm
