Data Acquisition

Yes, provided the piezometer’s frequency range and coil resistance are within the typical limits—roughly 400 to 5000 Hz and under 200 ohms. Most standard vibrating wire sensors from established geotechnical brands fall within this range. The excitation voltage and measuring resolution are pre-set to match common models.

It depends on the channel configuration. A base unit might offer 8 or 16 single-ended channels, expandable via multiplexers. For mixed sensor types, some channels can be software-configured, so you don’t lose capacity by using one channel type for another. If your project has more than 50 sensors, it’s worth talking to Kingmach about a customized node architecture.

By default, logged data comes as CSV or SDI-12 records. Both formats can be pulled into monitoring software like Campbell’s LoggerNet, Geokon’s GK-404, or open-source solutions. The timestamp format is adjustable to UTC or local time, and the header includes channel ID, sensor type, and engineering units.

The standard enclosure is IP66 rated, which handles rain, dust, and temporary submersion. For monitoring points in manholes or flood-prone areas, a fully submersible IP68 version is available as a special order. All external connectors are industrial M12 or cable gland types, not consumer-grade USB plugs.

Yes, traceable calibration for the analog inputs can be done in-house before shipment. This is useful if you’re integrating the logger into an accredited monitoring program. The certificate covers voltage and current input accuracy over the calibrated range, typically at 3–5 points.
