Amcorder UG

Underground Recording Ammeter

Collect & analyze load profiles

Use on Underground Circuits

Open CT sensor with ±1% accuracy

Easily clamps to the line in seconds & is submersible





The Amcorder UG uses the same sensor technology and topology as the SensorLink® Ampstik®. The True RMS inductive sensor does not use magnetic materials and has no moving parts. The opening of the sensor is electronically closed and external currents are electronically rejected. The accuracy, external current reject, and range of currents measured by the patented amp sensor substantially exceed the performance of the best clamp-on sensors.


The key feature is the ability to leave the Amcorder UG deployed on an elbow to record average current readings every few minutes for 30+ days. It easily attaches to the line with a standard shotgun style hot stick. Once on the line, it immediately begins to collect and record the current load.


The housing of the Amcorder UG is made of urethane and is built to operate safely, even in severe utility environments. It is resistant to shock and is unsusceptible to flame. It also operates within a wide temperature range. The Amcorder UG has a nonconductive clamp assembly, which allows it to securely hang vertically beneath the elbow.


The Amcorder UG is equipped with an infrared USB port for communicating the recorded data into the user’s PC. The data is downloaded through SensorLink’s Softlink software. Softlink is a user friendly software interface that allows the user to download, view, graph and export data from the Amcorder UG. The data directly transfers from
the Amcorder into Softlink through an Infrared Port.
