Displacement Transducers Built to Your Specifications
Off-the-shelf displacement sensors often fall short when a borehole is too narrow, the travel too long, or the output signal needs to match legacy loggers. We have seen these gaps slow down tunneling and slope stabilization work. Kingmach approaches these projects by starting with your measurement parameters—range, resolution, physical envelope—and then configuring or building a transducer to fit. The result is a sensor that drops into the existing monitoring scheme without forcing you to re-engineer the data chain. From small soil extensometers to large settlement arrays, the ability to specify things like flange mounting, cable length, or 4-20mA output keeps installation straightforward. This way, the instrument serves the job, not the other way around.
Technical Detail
Kingmach manufactures geotechnical instruments in-house, which means we can modify displacement transducers without the lead times and markups of third-party customization. Common requests include adjusting the measuring range from a few millimeters up to several hundred, selecting rod or cable actuation, and sealing the housing for long-term submersion. For dam and tunnel monitoring, we often build units with remote zero adjustment and temperature compensation to handle seasonal drift. Outputs cover the usual voltage and current loops, as well as RS485 digital strings when many sensors share a single cable. The design process is straightforward: share your required precision class, physical constraints, and the environmental conditions like humidity or dust. We then propose a configuration based on proven internal mechanisms—potentiometric, LVDT, or magnetostrictive—backed by test data from our calibration benches. Since we keep a stock of components and produce to order, the turnaround for a custom batch is typically shorter than many expect. After delivery, our application engineers can walk your team through wiring, mounting, and signal scaling, often remotely. This direct support has proven useful on jobs in remote locations where sending a specialist isn’t practical.

FAQ
Most jobs start with measuring range, physical mounting dimensions, and output signal type. From there we adjust cable length, connector style, and sealing. You can also specify rod or cable actuation, return mechanism (spring or gravity), and whether you need integrated temperature compensation.
It depends on the complexity and our current production schedule. A batch with minor modifications often ships in 3-5 weeks. Larger redesigns or environmental testing can push that to 8 weeks or more. We’ll confirm a timeline after reviewing your requirements.
Yes, every transducer goes through our calibration bench and ships with a traceable certificate. We can include specific test points you need and document the results. If your project requires third-party accredited calibration, we can coordinate that as well.
In most cases yes. We match the electrical output to your logger’s inputs—commonly 0-10 V, 4-20 mA, or RS485. Our engineers can provide wiring diagrams and help with scaling equations. If the logger uses a proprietary protocol, a small signal conditioner often bridges the gap.
We do, though minimum order quantities apply for certain deep customizations. If your request can be met by tweaking our standard platform, we can often fulfill a single unit. Just send us your specs and we’ll let you know what’s possible.
