Component Specifications

Definition
A specialized electrical cable designed to transmit low-voltage analog or digital signals from temperature sensors to monitoring and control systems. It features multiple conductors with shielding to prevent electromagnetic interference, ensuring accurate temperature readings in industrial environments. These cables maintain signal integrity over distances while resisting environmental factors like temperature fluctuations, moisture, and mechanical stress.
Working Principle
Signal cables operate by providing a conductive pathway for electrical signals generated by temperature sensors. The cable's conductors carry voltage or current variations corresponding to temperature measurements, while shielding layers (typically foil or braid) protect against electromagnetic interference that could distort signals. Twisted pair configurations reduce crosstalk between conductors, and insulation materials prevent short circuits while maintaining flexibility for installation.
Materials
Copper conductors (stranded for flexibility), PVC or polyurethane insulation, aluminum foil or copper braid shielding, PVC or thermoplastic elastomer outer jacket. May include drain wires for grounding.

Frequently Asked Questions

What is the difference between signal cable and power cable for temperature sensors?

Signal cables transmit low-voltage measurement signals (typically below 30V) with shielding for accuracy, while power cables deliver higher voltage to power sensors without requiring the same level of signal protection.

How often should signal cables be replaced in industrial applications?

With proper installation and environmental protection, signal cables typically last 5-10 years. Replacement is recommended when insulation shows cracking, shielding effectiveness degrades, or intermittent signal issues occur.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
