From Amperis: continuous hydrogen monitoring for power transformers. Inside a power transformer, the first sign of an internal fault is hydrogen. It shows up long before smoke, before an alarm, before an outage. Periodic oil sampling finds it weeks later, and only if the sample is taken at the right time. Between two visits, a transformer can go from healthy to failed. The GRIDSCAN 5000 measures dissolved hydrogen continuously, from 25 to 5000 PPM. It screws directly onto a tank valve, has no moving parts,
and runs unattended for its whole service life. The sensing element is solid state palladium alloy. No membranes, no calibration gases, no pumps, no chromatography columns. A patented self calibration corrects drift on its own, so the reading stays valid without ever removing the unit. It is built for the yard. IP 68: 7.6 metres of water for 14 days. C5 M marine corrosion class. Minus 40 to 70 degrees ambient, 105 in oil. 30 g shock.
It speaks Modbus RTU and DNP3 over two wire RS-485, straight into SCADA, with a 4 to 20 milliamp output for legacy equipment. And it logs one year of history on board, so a communications outage leaves no gap. Three versions. The 5000, for fleet wide monitoring. The 5000 HP, for critical assets that need earlier warning. And the 5010, which calibrates without interrupting the measurement. Installed with a wrench and a 4 wire cable, and delivering valid readings the same day.
