Instrumentation cable is generally used to transmit a low-power signal from a transducer (measuring for example, pressure, temperature, voltage, flow, etc.) to a PLC or DCS process control computer or to a manually operated control panel.
It is normally available in 300- or 600-volt constructions with a single overall shield, or with individual shields over each pair (or triad) and an overall shield.
For optimal performance, these interconnection cables have to be reliable, robust and offer shielded protection, whether an overall screen or individually and collectively screened cable, to resist electromagnetic interference.
