RDP Electronics can now provide a LVDT based liquid level measurement solution for use where other methods may be inappropriate. Typically, the LVDT?is fitted with a weighted float and installed with the transducer directed vertically downward towards the liquid surface.
This approach is suitable where the liquid inside may form a foam on top, precluding the use of optical devices. LVDTs can also be used in some Intrinsically safe (IS)?applications where the liquid may be flammable or surrounded by explosive gas.
Where there is a risk of liquid rising too high in the tank, then using submersible LVDTs will ensure the device is protected. The stainless steel body of the transducer reduces deterioration in corrosive or saline fluids.
