Heavy armored grain bin temperature cable for conventional vertical silo
Basic parameters:
Waterproof and anti fumigation
Tensile strength > 4T
Replaceable inner core
Strong wear-resistant and pressure resistant outer sheath
Outer sheath material: non regenerated high molecular weight polyethylene mixed with self-developed modified additives. High temperature resistance, wear resistance, high hardness and high smoothness.
Tensile parameter: ≥ 5T
Waterproof and anti fumigation: it can sink into water tanks and wells less than 100m. Effectively prevent moisture from entering and damaging the grain bin temperature cable.
Operating environment: it is recommended to use at – 50 ℃ – 120 ℃. It can be used in coal warehouse, corn warehouse below 60 meters, wheat warehouse and other grain warehouses. It can be used in deep-sea water less than 30m, water storage tank less than 100m and groundwater well.
Temperature measurement range: – 55 ℃ – 128 ℃
Temperature measurement accuracy: ≤ 0.5 ℃
Inner core of grain bin temperature cable: fill in the whole silicone and seal it. Effectively prevent moisture from entering and condensation. The inner core can be pulled out.
Temperature measurement chip: 18B20 9. Communication mode: 1-wire
Core color: black is GND (ground wire), and other colors are signal wires.
Working voltage: 0-5.5v
Structural features:
Product tensile strength: the outer sheath is composed of 30 high carbon steel wires. And through special treatment, the stress of each steel wire is uniform. It is different from the straight drawn steel wire of ordinary all inclusive grain bin temperature cable, resulting in excessive stress on single or multiple wires, resulting in local fracture.
Product waterproof treatment: the product is composed of temperature measuring inner core + inner core tube + tensile steel wire + outer sheath. The inner core is treated with integral pouring waterproof silica gel. It can effectively prevent condensation, water seepage and internal corrosion of the inner core. The technology has been mature and applied in hot springs, water storage tanks, tidal power generation, oil tanks and freezing shafts.
Advantages of product inner core: the whole inner core can be pulled out for easy replacement, the inner core is waterproof as a whole, and the material of the inner core is resistant to high temperature ≥ 125 ℃. The inner core of the product can be replaced with other kinds of grain bin temperature cables.
Outer sheath material: the outer sheath material of ordinary grain bin temperature cables in the market is generally PVC or high-pressure polyethylene. Very low wear resistance. Zs-7 heavy-duty replaceable core grain bin temperature cable is covered with non regenerated high molecular weight polyethylene and mixed with self-developed modified additives. It is protected by high strength, high wear-resistant polymer materials. It can be used in coal bunker and grain bunker with high wear index. High temperature resistance is superior to ordinary grain bin temperature cable.
The product is widely used: the product has the advantages of anti-wear, strong tensile resistance, waterproof, high temperature resistance, replaceable inner core and so on. This product is a plastic outer sheath. There are two inner cores inside. The bottom end is treated with injection molding process, and the tail die-casting steel wire ring is convenient to use. The protection grade is ip58. Both signal core and ground wire core use steel wire to transmit signals. N 18b20 temperature sensors can be built in. Double steel wires not only transmit signals, but also take into account the role of overall tension. The overall shape is flat, the stress area is smaller, and the tensile strength is higher than that of ordinary grain bin temperature cable.
product mix
Signal grain bin temperature cable and temperature measuring element
The default temperature measuring element is 18B20. If you need to customize the temperature measurement of thermal resistance and thermocouple, please explain in advance. The signal grain bin temperature cable uses 0.3 by default ²* 2 inner cores, two-wire system, or 0.3 ²* Three core three wire system.
Removable sheath
The sheath can be pulled and inserted, which is sealed with integral silica gel, which can prevent moisture from entering the inner core, prevent corrosion and prevent condensation. It can be replaced by pulling and inserting, which is convenient for maintenance.
Inner sheath
The inner sheath is made of high temperature resistant and wear-resistant materials by default. If other materials are required, please customize them in advance. 4. Embedded steel wire
The steel wire is composed of 30 single high carbon steels by default. If 20-40t version is required, it can be customized in advance.
The outer sheath of high polymer wear-resistant sheath is “non regenerated high molecular weight polyethylene mixed with self-developed modified additives” by default, which is wear-resistant and high temperature resistant. Cross linked polyethylene material can be customized (for high voltage line, high temperature resistance). Or ordinary grain bin temperature cable sheath can be customized.
