Product details
Key Features
- Waterproof and fumigation-resistant construction: Designed to protect internal temperature sensors against moisture intrusion and corrosive fumigation environments.
- High tensile strength: Manufacturer-rated tensile capacity of 11 tonnes-force.
- Replaceable sensor core: Internal temperature-sensing assembly can be removed and replaced without replacing the outer protective cable structure.
- Heavy-duty steel reinforcement: An armored layer consisting of 58 high-carbon steel wires distributes tensile forces across the cable.
- High abrasion and compression resistance: Thickened polymer outer sheath provides protection against mechanical wear, pressure, and corrosion.
- Enhanced temperature resistance: Designed for demanding industrial storage environments.
- Multipoint digital temperature monitoring: Supports DS18B20 temperature sensors using 1-Wire communication.
- Two- or three-wire configurations: Available with 2-wire or 3-wire internal signal conductors.
Additional Details
The ZS-11 is a heavy-duty armored multipoint temperature monitoring cable designed for coal storage silos, pulverized coal storage facilities, and other demanding bulk-material monitoring applications.
It is suitable for coal lump storage silos and pulverized coal silos up to 20 meters in height, where monitoring cables are exposed to substantial tensile forces, abrasion, compression, and challenging environmental conditions.
The cable incorporates an armored reinforcement layer consisting of 58 high-carbon steel wires, specially arranged to distribute mechanical loads evenly. This construction reduces localized stress on individual reinforcement wires and provides greater resistance to tensile forces than conventional temperature monitoring cables.
Its outer sheath is manufactured from virgin high-molecular-weight polyethylene blended with specialized performance-enhancing additives. The sheath is approximately three times thicker than conventional designs, providing increased resistance to abrasion, compression, corrosion, and elevated temperatures.
The ZS-11 also features a removable temperature-sensing core encapsulated in waterproof silicone. This construction helps prevent moisture intrusion, internal condensation, and corrosion while allowing the sensor assembly to be withdrawn and replaced when necessary.
Combining high tensile strength, abrasion resistance, waterproof construction, and a serviceable sensor core, the ZS-11 is designed for long-term temperature monitoring in demanding coal storage environments.
