jointmeters

They’re commonly used on concrete dams, tunnel linings, retaining walls, and bridge abutments. The sensor bridges the gap between two anchored points, so any relative displacement gets captured. In rock mechanics, they also monitor fissures in slope stability projects.

It depends on the data acquisition setup. Vibrating wire jointmeters are good for long-term, remote monitoring because they transmit frequency signals over long cables without signal loss. Potentiometric types output voltage or resistance, which suits short-distance connections and simpler readout boxes. Both give stable measurements if installed correctly.

Yes, many Kingmach models are rated for submersion up to a specified water head. The cable entry is potted, and the housing seals prevent water ingress. For deep submersion or high-pressure zones, confirm the pressure rating with our application engineers.

A field calibration check can be done using a micrometer fixture if the sensor is removable, or by inducing a known displacement with a mechanical jig. Each sensor comes with a factory calibration sheet, and our technical team can guide you through the verification steps.

Standard models usually ship within two weeks. Customized versions with non-standard ranges, cable lengths, or connectors normally take four to six weeks, depending on the complexity. We’ll give you a schedule when the order is placed.
