Toshiba LF664 Instruction Manual page 40

Principal materials:
Case・・・・carbon steel
Lining・・・Natural rubber
Electrodes・・・AISI316L (std.), Titanium (opt.), Hastelloy C equivalent (opt.)
Grounding rings・・・None (std.), AISI304(opt), AISI316(opt), Titanium (opt.),
Measuring tube・・・AISI304
Coating: Polyurethane coating (std.), pearl-gray colored
Note: If the optional IP68 and NEMA 6P continuous submersible type structure is specified,
the coating is tar epoxy resin coating.
Cable connection port: 1/2-14NPT male screw for both signal cable and exciting cable.
Cable length: Allowable cable length between the converter and the detector varies with the electrical
conductivity of fluid. See Figure 9.1.
