1. Product Overview
The waterproof and anti-corrosion temperature measuring cable is specially designed for grain storage applications. By integrating high-precision temperature sensors inside the cable, it provides real-time monitoring of the temperature inside grain piles and transmits the data to the upper computer or monitoring system. With its waterproof and anti-corrosion structure, the cable can withstand high humidity, dust, and harsh chemical environments, ensuring long-term stability and reliability when buried in grain.
2. Key Features
Excellent Waterproof Protection
Outer sheath made of high-polymer composite material, with IP65–IP68 protection rating, effectively preventing moisture ingress.
Anti-Corrosion & Aging Resistance
Resistant to acids, alkalis, and salt fog, suitable for various climates and storage environments.
High-Accuracy Measurement
Built-in imported temperature sensors, measuring range -40℃ to +85℃ with accuracy up to ±0.2℃.
Multi-Point Measurement
Supports multiple measurement points (e.g., every 1.5 meters), enabling three-dimensional monitoring inside the grain pile.
Strong Compatibility
Provides RS485/Modbus RTU interface, fully compatible with existing grain monitoring systems.
Easy Installation & Maintenance
Customizable cable length; optional replaceable-core design reduces maintenance costs.
