Immersion & wet locations

Suitable

Hydrolysis-resistant ether-grade PUR/TPU jackets, water-blocked cores and optional atmospheric vent tubes support permanent immersion.

Free-hanging vertical run

Suitable

Integrated aramid yarns or galvanized steel wire armour allow direct vertical probe suspension in sea cages, wells and stilling tubes.

Fixed installation

Suitable

Foil plus tinned copper braid screening protects low-level mV, 4–20 mA, SDI-12, RS-485 and optical DO signals from pump VFD noise.

Offshore platform & shipboard deck trays

Suitable

Resists bio-fouling cleaning agents, saline splash, sunlight and −30/−40 °C winter freeze around open aquaculture tanks.

Energy chain / drag chain

Not suitable

Submersible water-quality probe cables are designed for static/suspended immersion rather than high-speed machine drag chains.
