Immersion & wet locations
Hydrolysis-resistant ether-grade PUR/TPU jackets, water-blocked cores and optional atmospheric vent tubes support permanent immersion.
Product
Vented TPU Water Quality Cable featuring central atmospheric vent tube and subsea / marine outer protective sheath (ISO 15839 / IEC 60770, 300 V, -30 to +80 °C, min. bend radius 6 × OD).
Typical values for this cable type, based on ISO 15839 Vented TPU Submersible Water Quality & Level Sensor Specification — confirmed in the datasheet and quotation for your order.
Application fit
Vented TPU Water Quality Cable featuring central atmospheric vent tube and subsea / marine outer protective sheath (ISO 15839 / IEC 60770, 300 V, -30 to +80 °C, min. bend radius 6 × OD).
Hydrolysis-resistant ether-grade PUR/TPU jackets, water-blocked cores and optional atmospheric vent tubes support permanent immersion.
Integrated aramid yarns or galvanized steel wire armour allow direct vertical probe suspension in sea cages, wells and stilling tubes.
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.
Resists bio-fouling cleaning agents, saline splash, sunlight and −30/−40 °C winter freeze around open aquaculture tanks.
Submersible water-quality probe cables are designed for static/suspended immersion rather than high-speed machine drag chains.
