Displacement Meter: Practical Field Monitoring
displacement meter
On a monitoring site, the difference between catching a shift early and missing it often comes down to the instrument you rely on. A displacement meter isn’t just a device—it’s how you keep tabs on cracks, joints, and structural movement in real time. At Kingmach, we put together a range of these meters with the everyday field engineer in mind. Our line covers everything from simple analog readouts to digital loggers that can sit remote for months. No flashy claims—just instruments that have been proven in tunnels, slopes, and foundations. We’ve learned that one size never fits all, so customization is part of the process. If your project needs a specific range or output, we’ll work with you to make it happen.
Technical Detail
Configured around process stability, mold life, and long-term uptime.
Kingmach displacement meters are built for engineers who need straightforward, dependable readings from geotechnical structures. The product range includes linear potentiometer types for monitoring crack widths and joint openings, as well as vibrating wire variants where long-term stability is a priority. Many of our sensors come in standard 50mm, 100mm, and 200mm ranges, but we regularly adjust those figures for larger movements. The housing is stainless steel, IP65 rated, and the units have survived heavy rain and dust in a good number of tunnel and dam projects. Output options cover 4-20mA, RS485, and vibrating wire signals, so they plug into most logging systems without much hassle. You won’t find exotic materials or over-engineered specs—just practical choices like polyurethane cable, optional protective covers, and mounting brackets that can be welded or bolted in place. Our technical support team is China-based with distribution partners worldwide, meaning we can offer quick troubleshooting and after-sales service. For project-specific needs—extended rods, non-standard cable lengths, or different crest tables—we take custom orders. That flexibility, along with our wide product range, is what usually keeps clients coming back for multiple phases of work.

Common technical questions
What’s the typical measuring range of your displacement meters?
Our standard linear potentiometer units come in 50mm, 100mm, and 200mm ranges. Vibrating wire models often go up to 300mm. We can also build custom ranges if your project involves larger deformations.
Can these meters connect to an existing data logger?
Yes, we offer 4-20mA, RS485, and vibrating wire outputs, so integration shouldn’t be a problem. Just let us know the logger model and input type before ordering, and we’ll match the signal.
How do I install a displacement meter across a crack in concrete?
You’ll typically need to fix mounting brackets on both sides of the crack with expansion bolts or epoxy. The meter body attaches to one bracket, and the extension rod to the other. We include a simple manual with diagrams, and the team can walk you through it if the geometry is unusual.
Are these meters suitable for long-term settlement monitoring in soft ground?
Yes, many clients use our vibrating wire displacement meters for that purpose. They handle temperature changes well and don’t drift significantly over time. Pairing them with a settlement plate and a remote terminal unit gives you reliable long-term data.
Do you offer waterproof versions for submerged conditions?
Standard units are IP65, which handles rain and high humidity. If the meter needs to work underwater, we can upgrade sealing and add a pressure compensation tube. It’s a common request, so we know how to keep it watertight without changing the core mechanics.
