Ballast Water in the Wing and
Double Bottom Tanks
The ballast water tank level measurements in the wing and double bottom tanks go directly into the calculations for ship trim, draught and list. Since the measuring sites during operation on board are virtually inaccessible, reliability and stability are an absolute must. Pressure shocks, abrasive sand particles and brackish water place additional heavy demands on the instrumentation.
Pressure Shocks from Constant Empty and Fill Operations in the Ballast Tanks
The rugged sapphire ceramic measuring cell of the VEGAWELL 72 can withstand pressure shocks up to 60 times higher than the nominal measuring range and is characterised by high resistance to corrosion. The ruggedness and elasticity of the ceramic diaphragm make this an ideal instrument for the constant shocks resulting from emptying and filling of the ship's ballast tanks. The encapsulated stainless steel housing are either class IP 68 or IP 69K, and provides reliable protection against external moisture for the electronics and measuring cell.
Extreme Applications
Thanks to its separate electronics, sensor housing in IP 69K and ceramic measuring cell, the VEGABAR 66 is the perfect sensor for harsh conditions. The mounting bosses, which are located on deck, are sealed with the stainless steel process fittings and thus withstand the effects of the atmosphere or breaking waves. The separate electronics can be installed and ventilated in a protected area. |
