1. Product Overview
The Precision Digital Multipoint Temperature Monitoring Cable is a high-strength intelligent sensing product independently developed by Langfang Zhaosui.
It is specially designed for vertical storage silos such as grain silos, coal silos, and lime silos, integrating multi-point temperature measurement, digital signal output, moisture-proof and explosion-proof protection, and a reinforced armored structure.
This cable offers modular replaceable design, excellent tensile strength, stable data transmission, and easy maintenance, making it a preferred solution for industrial and agricultural temperature monitoring systems.
Applicable silo types:
- Grain silos: 10 – 40 m height
- Coal silos: within 10 m
- Lime silos: within 20 m
2. Structural Features
1. Modular Replaceable-Core Design
The Precision Digital Multipoint Temperature Monitoring Cable adopts a detachable structure consisting of an armored sheath layer and an inner temperature-sensing core.
When the core is damaged, it can be quickly replaced without removing the armored layer - dramatically reducing maintenance costs and downtime.
2. High-Strength Armored Protection
The outer layer is composed of 30 high-strength steel wires, forming a robust armored protection layer.
It withstands tensile forces over 7 kN (≈ 7 T), ensuring reliability and safety even under fully loaded grain conditions.
3. Superior Waterproof and Explosion-Proof Capability
With an IP67 protection rating, the cable is both dust-tight and waterproof.
It meets international explosion-proof standards including
Ex iaD 20 T85 °C, Ex ib IIB T6 Gb, and Ex ia IIC T6 Ga,
making it suitable for use in dusty and flammable environments.
4. Durable Outer Jacket
The outer sheath is made from non-recycled high-molecular-weight polyethylene (PE) mixed with anti-abrasion and anti-aging additives.
It maintains excellent mechanical and insulation performance even under long-term exposure to high temperature, humidity, and friction.
With its rugged construction, digital communication, and service life exceeding 8 years, the Precision Digital Multipoint Temperature Monitoring Cable represents a reliable, cost-effective, and intelligent solution for safe grain storage and industrial temperature management.
