Structure of Apolarm-C
CSR-3005E
Water-weathering structure
Floater is composed of three resin moldings and their jointing faces are welded.
The section through which cable is led out is double-sealed by means of grand packing and
bonding agent.
(2) Detectable oils
As written in specifications, this detector can detect the presence of petroleum items,
animal oils, organic solvent solutions, etc.
Apolarm-C has a structure capable of detecting such high viscosity oils as C heavy oil,
minus heavy oil, grease, as well.
(a) Necessary conditions to be detected
①
To be smaller than water in specific gravity.
②
To be not water-soluble
(Ether, methanol, etc. cannot be detected.)
③
Dielectric constant is not larger than 5.
