The Vertical Silo Temperature Monitoring Cable is a specialized temperature-sensing cable designed for monitoring bulk materials such as grain, cement, coal, and similar commodities stored in large vertical silos. It is widely used in steel silos, flat warehouses, and other large-scale storage facilities.
Multiple temperature sensors are integrated along the length of the cable, enabling continuous and real-time monitoring of temperature distribution at different heights inside the silo. This allows early detection of abnormal temperature rise, mold development, or self-heating risks, providing reliable data support for safe storage management.
The cable is typically protected by a high-strength polyethylene (PE) outer jacket, offering excellent resistance to abrasion, moisture, and corrosion. Inside the cable, high-tensile steel wires (such as aviation-grade steel wires) are incorporated as load-bearing elements, significantly enhancing tensile strength and ensuring long-term stable operation under harsh conditions such as high material pressure, friction, and prolonged vertical suspension.
Main Technical Specifications
1.Material & Structure
The cable features a weather-resistant polyethylene (PE) outer jacket designed for long-term use in harsh silo environments.
Inside, high-strength aviation-grade steel wires (typically Φ5.0–Φ8.0) are integrated as tensile elements, ensuring the cable will not break under vertical suspension and heavy material pressure inside the silo.
2.Internal Conductors
Tinned copper conductors with a cross-sectional area of 0.3 mm² or 0.32 mm² are commonly used.
The number of conductors is configurable according to the required number of temperature measurement points, typically ranging from 6 to 20 cores.
3.Temperature Sensors
Embedded DS18B20 digital temperature sensors are used, providing high accuracy, stable readings, and reliable long-term performance.
4.Tensile Strength & Load Capacity
The internal steel-wire structure offers excellent load-bearing capability, with a tensile strength of approximately 2.8 tons to 5.3 tons, making the cable suitable for tall vertical silos and high material loads.
5.Operating Temperature Range
Designed to operate reliably within an ambient temperature range of –40 °C to +60 °C.
