Signal Wires: Temperature Range -60°C to 200°C

Component Specifications

Definition

Signal wires are specialized electrical conductors designed to transmit low-voltage analog or digital signals from temperature sensors to monitoring, control, or data acquisition systems. These wires maintain signal integrity by minimizing interference, voltage drop, and noise, ensuring accurate temperature readings in industrial environments. They typically feature shielding, specific insulation materials, and precise conductor configurations to handle the sensitive output signals from thermocouples, RTDs, or thermistors.

Working Principle

Signal wires operate by providing a conductive path for electrical signals generated by temperature sensors. The wires carry minute voltage or current changes corresponding to temperature variations from the sensor element to the processing unit. Shielding and twisted-pair configurations reduce electromagnetic interference (EMI) and crosstalk, while proper insulation prevents signal degradation from environmental factors like moisture, heat, or chemicals.

Materials

Copper conductors (stranded or solid), PTFE (Teflon) or PVC insulation, aluminum or copper braided shielding, PVC or polyurethane outer jacket. Conductor sizes typically range from AWG 24 to AWG 16.

Frequently Asked Questions

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

Signal wires transmit low-voltage analog or digital signals with minimal interference, while power wires deliver higher current to power the sensor. Signal wires often have shielding and specific impedance requirements.

How do I select the right signal wire for my temperature sensor?

Consider sensor type (thermocouple, RTD), temperature range, environmental conditions (moisture, chemicals), required length, and compatibility with existing connectors and systems.
