Vibrating Wire Strain Gauges for Bridge, Tunnel & Dam Monitoring: Complete Selection Guide

Smart Formwork Axial Force Meter (VW)
Formwork design relies on accurate force data to avoid overloading or premature stripping. Kingmach’s Smart Formwork Axial Force Meter uses a vibrating wire (VW) sensing element to track axial loads directly in the field. The output is a frequency signal, which holds up better over long cable runs in damp, electrically noisy jobsites compared to voltage-based instruments. Readings stay consistent over months, so you can monitor curing and staging without constant recalibration. Installation is straightforward: the meter is sized for typical tie-rod or spindle connections, and the rugged housing handles concrete splash and vibration. Kingmach stocks variants for common load ranges and can adjust end fittings or cable lengths when the project calls for it. Whether you’re working on bridge piers, slab formwork, or tunnel linings, the VW meter gives you a direct look at what the formwork is carrying.
Technical Detail
Kingmach produces a wide range of geotechnical and structural monitoring instruments, and the smart formwork axial force meter fits into that lineup as a practical choice for construction monitoring. The heart of the unit is a vibrating wire load cell sealed in a stainless steel body. Frequency output means the signal does not degrade with distance, which is a real advantage on sprawling sites where cable runs can exceed 100 meters. You can connect the meter to Kingmach readout units or third-party data loggers that accept VW inputs. Many users route data into automated logging systems to track force trends overnight or during concrete pours. The sensor comes pre-calibrated, with a calibration sheet included. Standard full-scale capacities cover the typical range found in most formwork designs, and custom ranges are available if your design has unusual tie-rod spacing. The construction is weatherproof, and the cable entry is sealed against moisture ingress. From a supply standpoint, Kingmach maintains regional distributors in several countries and provides direct engineering support during setup. If your monitoring plan includes additional parameters—like concrete strain, temperature, or tilt—the company can supply complementary sensors and help integrate them into a single data stream.

The meter typically installs in line with the tie rod or spindle. You’ll need bearing plates on both sides to distribute the load. Kingmach supplies standard plates, but if your rod size is different, they can machine custom adapters. Tighten the assembly as you normally would, and the meter reads the force passing through.
The sensor outputs a frequency, so you need a device that can excite and measure a vibrating wire gauge. Kingmach offers handheld readouts, or you can connect to many brands of dataloggers. For continuous monitoring, the 4-pin connector plugs into a centralized logger with VW channels.
Yes, as long as it’s not overloaded beyond its safe limit. Remove it carefully after stripping the formwork, clean off concrete residue, and check the threads. The calibration should hold, but we recommend a spot-check with a known load if you’re pushing a tight schedule.
The meter has an internal thermistor, so you can measure temperature and correct the force reading manually or in software. The steel body and wire are designed to minimize thermal zero shift, but for precise measurements, temperature correction is a standard practice.
It depends on the modification. A non-standard full-scale range with the same mechanical dimensions usually takes about two to three weeks because it’s a different sensing element. Changes to end fittings or cable length are faster. Kingmach’s support team can give you a firm date once they see your specs.
