Load Cell Wire for Industrial and Geotechnical Systems
load cell wire
When a load cell gives erratic readings, the culprit often isn’t the sensor itself—it’s the wire. A cheap, poorly shielded cable can turn precise millivolt signals into noise. Kingmach’s load cell wire is built to prevent exactly that. We supply 4-core and 6-core shielded cables that work with most strain-gauge load cells, from bench scales to road weighbridges. Over the years, we’ve seen too many projects delayed because standard wiring failed in wet or high-interference environments. That’s why our wires use tinned copper braid and PVC or PUR jackets—they hold up in real conditions, whether it’s a dusty cement plant or a monitoring station on a dam. And because every setup is different, we cut to custom lengths and can pre-fit waterproof connectors if you need them. No minimum order for samples, either.
Technical Detail
Configured around process stability, mold life, and long-term uptime.
Kingmach’s load cell wire portfolio covers the common configurations you’ll actually need. We keep 4-core and 6-core cables in stock, with tinned copper braid shielding that handles most industrial noise. The insulation is typically PVC for indoor scales or PUR for outdoor installations—both resist oil and moisture better than standard commercial cables. Conductor sizes range from 0.2mm² to 0.5mm², so you can match the wire to your load cell’s excitation voltage without adding unnecessary cost. What makes these wires practical is the little things: the jacket printing includes meter markings, which makes on-site cutting cleaner; the color coding follows the standard red-black-green-white scheme, so your technician won’t have to guess which wire is which. For harsh environments, we can supply cables with a stainless steel overbraid or Teflon insulation. Since we’re a geotechnical instrument manufacturer ourselves, we understand how a bad cable can ruin a monitoring project—we test every batch for insulation resistance and shield continuity. That’s why mining companies and bridge monitoring crews keep coming back. And if your project needs a specific length or connector type, we’ll make it happen without a huge MOQ.

FAQ
Common technical questions
What’s the difference between 4-core and 6-core load cell wire?
4-core cables combine excitation and sense lines (sensing is handled at the indicator), which is fine for most short-run installations. 6-core cables have dedicated sense wires that compensate for voltage drop over long distances—essential when the junction box is 30 meters or more from the load cell.
Can I use the same load cell wire for outdoor weighbridges and indoor bench scales?
You can, but it’s not ideal. Indoor bench scales usually only need PVC-jacketed wire, which is cheaper and more flexible. Weighbridges and outdoor applications should use PUR or polyethylene jackets to handle temperature swings, UV exposure, and moisture. It’s a small price increase for much longer service life.
How do I know if I need shielded or unshielded load cell cable?
If there’s any AC power wiring, motor drives, or radio transmitters nearby, you need shielded cable. Unshielded wire acts like an antenna—it picks up electromagnetic interference that makes the weight reading drift. Even in a quiet environment, shielding is cheap insurance against intermittent faults.
Do you offer custom-cut lengths with connectors pre-attached?
Yes, we can cut to the exact meter and fit waterproof connectors, strain reliefs, or even conduit-ready glands. Tell us your connector type, pinout, and overall length, and we’ll ship ready-to-install cables. This is especially helpful for field teams who don’t want to solder on site.
What’s the typical lead time for load cell wire orders?
Standard cables in common sizes usually ship within 2-3 working days. Custom lengths or non-standard jacket materials might add a few days. If you’re on a tight schedule, let us know—we often can adjust production priority.
