Vaisala MHT410 Moisture, Hydrogen and Temperature Transmitter

Why to Measure Hydrogen?

Hydrogen is a general gas that is generated in various transformer faults. Hydrogen measurement is used for example as a simple early warning indicator in power transformers before actual failure occurs. 

Hydrogen Probe MHT410 Design

What Makes Our Hydrogen Measurement Unique?

The Vaisala MHT410 combines a pair of thin film sensors with a temperature sensor to provide direct real-time measurement of the Hydrogen and Moisture in oil.  Most importantly, by using the sensors in line in the oil, you get long-term field operation with no consumables or maintenance costs.

  • Hydrogen measured directly in oil.
  • Humicap® Sensor measures true relative saturation (%RS) in oil.
  • Highly selective sensors immune to oil contaminants.
  • No membrane or other consumables.
  • No pumps or mechanical parts to maintain.

Benefits of Hydrogen Measurement

Real-Time View

Online monitoring of hydrogen and moisture in the insulating oil of power transformers provides a real-time view of transformer condition. Real time date ensures that maintenance is optimized.

Extended Lifetime

Continuous monitoring of hydrogen and moisture with an in-situ probe is the first step in extending the lifetime of a transformer through implementation of condition based maintenance (CBM) practices, leading to a lower total cost of ownership.
