Instrumentation and thermocouple cable buyers in Louisiana
In a Louisiana plant, instrumentation cable is the most technical thing in the store and the easiest to mis-price, because its value sits in the pair count and the shield.
Start here 01
Sell instrumentation cable in Louisiana
Instrumentation cable carries low-level analogue and digital signals between field instruments and control systems. It is built as pairs or triads, individually or overall shielded, in 16 to 24 AWG, with thermocouple extension cable using matched alloys so the junction compensation stays correct.
- Construction, size and footage, not weight alone
- Reel tags and jacket print travel with the lot
- Pickup planned around your site, not ours

What this family covers 02
Instrumentation and thermocouple cable we review in Louisiana
Refineries, chemical plants and LNG trains run it by the mile during construction and turnarounds, and revisions to a control philosophy leave reels behind that no longer match the specification. Those reels are still valuable, but only to a buyer who knows what the print means.

Identification 03
What identifies instrumentation cable
The facts that decide how a lot is read. Send what the reel says rather than a description from memory.
| Voltage rating | 300 V and 600 V instrument cable; thermocouple extension cable is rated for its application |
|---|---|
| Construction | Pairs and triads, individually shielded, overall shielded, or both |
| Sizes we see | 16 AWG through 24 AWG, with 18 AWG and 20 AWG most common |
| Thermocouple types | Type J, K, T and E extension cable with matched alloy conductors |
| Condition markers | Print legibility, shield continuity at the cut, jacket condition, reel integrity |
| What identifies it | Print with pair count and AWG, the shield description, and the thermocouple type letter |
If a detail is unknown, mark it unknown. A stated uncertainty is workable. A guess that turns out wrong costs everybody a second visit.

Constructions 04
Instrumentation and thermocouple cable lots we buy
Read separately, because they are valued separately.
Multi-pair instrument cable
8, 12, 24 and 36 pair assemblies from control system work, read on pair count, AWG and shield.
Thermocouple extension cable
Type J and Type K extension cable, where the alloy and the type letter decide the value.
Individually shielded pairs
Cable with a shield on every pair, used where cross-talk matters. Read on construction, not just pair count.
Armoured instrument cable
Constructions with an interlocked armour for tray and exposed routes.
How a lot is read 05
How instrumentation cable is evaluated
Pair count, AWG, shield arrangement and thermocouple type are the four facts, and all four are usually printed. A reel with a legible print can be matched to a control system in minutes; a reel without one is a coil of small conductors.
Age and storage come next. Instrument cable is sensitive to moisture in the shield and to jacket hardening, and both are common in Louisiana stores. The review asks where it was kept rather than assuming.
Safety first. Instrument circuits are frequently live at low voltage and connected to systems that cannot be disturbed. Removal from a live plant is the plant's work under its own permit.

Instrumentation cable questions
What is the difference between instrumentation and control cable?
Instrumentation cable carries low-level analogue and thermocouple signals with tight shielding and pair construction. Control cable carries switching and status circuits at 600 V. They are different products and are reviewed separately.
Do you buy thermocouple extension cable by type?
Yes. Type J, K, T and E extension cable is read on the type letter, the alloy, the AWG and the remaining length. A mixed box of types is read as mixed.
Is armoured instrument cable worth more?
It suits more routes, so it can widen the buyer pool. The armour is not the value; the pairs and the shield are.
What if the shield has been cut back?
That is normal at a termination. What matters is whether the shield is intact along the reel and whether the cut end has taken water. Photograph the end.
