Instrumentation & Multi-Pair Screened Cable

Instrumentation Cable & Screened Multi-Pair Cable for Process Control and Sensor Wiring

Instrumentation cable and screened multi-pair cable carry the low-voltage signals that keep process control panels, PLCs and condition-monitoring systems talking to field devices without picking up electrical noise. This range runs from single-pair PVC and LSZH options through to higher pair-count cable like our 8-pair screened instrumentation cable, plus sensor-specific cable for accelerometers and probes. If you're working out pair count and gauge for a longer run, our Instrumentation Cable Sizing Guide is worth checking before you order.

What's in This Range

• 2-Pair Screened Instrumentation Cable — 0.5mm PVC screened instrumentation cable for standard process signal runs where twisted-pair screening is enough to keep noise out.
• 4-Pair Screened LSZH Instrumentation Cable — low-smoke zero-halogen instrumentation cable for indoor and enclosed-space installs where fire performance matters.
• 3-Core Screened Instrumentation Cable — Electra screened cable built for sensors and transmitters that need a common return conductor.
• Accelerometer Cable — shielded, shield-grounded accelerometer cable built for vibration sensors on rotating plant and machinery.
• Eddy Current Probe Cable — armoured eddy current probe cable for proximity and displacement sensors in condition-monitoring setups.
• Shielded Twisted Pair Cable — multi-pair screened twisted pair cable for control room and switchboard signal wiring.

Who Uses This

Instrumentation technicians and control panel installers pull this cable through cable trays and conduit on refineries, water treatment plants and food and beverage processing lines, where screened runs protect 4-20mA and analogue signals from VSD and switchgear noise. Condition-monitoring and reliability teams use the accelerometer and eddy current probe cable on rotating machinery — pumps, compressors, gearboxes — to feed vibration data back to monitoring systems. Data and comms installers reach for the shielded twisted pair cable when running signal wiring between switchboards and control rooms on commercial and industrial fit-outs.

Instrumentation Cable — Common Questions

What's the difference between instrumentation cable and standard screened data cable?

Instrumentation cable is built for low-level analogue and 4-20mA signals, with tighter screening tolerances to hold signal accuracy over long runs. A general-purpose screened data cable suits digital communication and control wiring instead. Our 2-pair and 4-pair screened instrumentation cable are sized specifically for process signal applications.

Do temperature probes and sensors need a specific extension cable?

Yes — probes and sensors need extension cable matched to their signal type and connector. Our fibre optic temperature probe extension cable is built for that exact application, keeping signal loss low over distance. A mismatched cable type can affect probe accuracy.

Do accelerometer and probe cables need to be armoured?

It depends on the environment. Armoured accelerometer cable adds mechanical protection on open cable tray or near moving machinery, while non-armoured shielded options suit protected conduit runs. Our Accelerometer Cable Guide covers 2-pin versus 3-pin options and when armoured or intrinsically safe cable is the better choice.
