WIRED MAGNETOSTRICTIVE LEVEL GAUGE
The magnetostrictive level probe bases his phisycal phenomena on the Wiedemann effect.
The main features are:
– Very high accuracy and repeatability –
– Reliability and robustness –
– Sharp leakage control –
– Full stainless steel execution –
– Ultra compact design –
Commonly used in the fuel level control, it allows the
measure of the three essential parameters:
– Fuel level –
– Water level on the bottom of the tank –
– Fuel temperature –
The magnetostrictive sensor measures with an high
resolution of 0,01 mm and a final accuracy of 0,25 mm
on the full scale range (Plus version only).
