RTD Flat Cable 1x3x0.22mm² SPC/PFA/SPCWB/PFA – Non-magnetic Laid Flat for 3-Wire Platinum Resistance Thermometers

RTD Flat Cable 1x3x0.22mm² SPC/PFA/SPCWB/PFA – Laid Flat, Conductor: SPC Silver Plated Copper Wire 7/0.20 (7 Strands), Insulation: PFA Compound, 1 Triad (3 Wires Not Twisted, Laid Flat), Screen: SCR Silver Plated Copper Wire Braiding, Sheath: PFA Compound Transparent, Temperature Range: -75°C to +250°C, Suitable for Connecting 3-Wire RTD Platinum Resistance Thermometers, Features: Abrasion Resistance, Rejects Electromagnetic and Electrostatic Interference

This RTD flat cable features 1x3x0.22mm² construction specifically engineered for 3-wire Platinum Resistance Thermometer (PRT / RTD) applications requiring accurate temperature measurement from -75°C to +250°C. The SPC silver plated copper conductors utilize 7/0.20 fine-strand construction, providing excellent conductivity, flexibility, and corrosion resistance for precise resistance measurement. PFA insulation delivers outstanding thermal stability, chemical resistance, and dielectric properties across the entire temperature range. The three wires are laid flat rather than twisted, maintaining consistent conductor spacing and minimizing lead resistance errors critical for 3-wire RTD configurations. An SCR silver plated copper wire braid screen provides comprehensive rejection of electromagnetic and electrostatic interference, ensuring signal integrity in electrically noisy environments. The transparent PFA outer sheath allows visual inspection of internal construction while offering exceptional abrasion resistance, chemical protection, and thermal stability. This flat cable design is ideal for connecting 3-wire platinum resistance thermometers in industrial process control, laboratory instrumentation, and precision temperature measurement applications.

FAQ

Q1: Why are three wires laid flat rather than twisted for RTD applications?

A: Laid flat construction maintains consistent conductor spacing and minimizes lead resistance variations critical for 3-wire RTD measurement accuracy, avoiding the added resistance variations that twisting can introduce.

Q2: What is the advantage of SPC silver plated copper conductors for RTD cables?

A: SPC provides low and stable resistance, excellent corrosion resistance, and superior solderability, minimizing lead resistance errors that directly affect RTD temperature readings.

Q3: Why is PFA insulation chosen for RTD cables?

A: PFA offers exceptional thermal stability from -75°C to +250°C, chemical resistance to industrial environments, and stable dielectric properties for reliable signal transmission.

Q4: What does the silver plated copper braid screen provide?

A: The SCR braid provides comprehensive rejection of both electromagnetic interference (EMI) and electrostatic interference (ESD), ensuring signal integrity in electrically noisy industrial environments.

Q5: Why is transparent PFA sheath beneficial?

A: Transparent sheath allows visual inspection of internal construction, braid coverage, and conductor alignment for quality verification while providing the same thermal and chemical protection as pigmented PFA.
