DGA 150/250/400 Series Hydrogen Monitors

The DGA 150/250/400 Series monitors are designed for new or retrofit monitoring of
hydrogen levels in oil filled transformers. The hydrogen monitors are available in models
calibrated for mounting either directly in the oil or in the gas space of nitrogen or air blanket
transformers

– use models only for the media specified. A valve is provided with a Luer

fitting which can be used both for bleeding gas and for drawing oil samples in oil space
installations.  Popular valve mountings are provided for retrofit:  1.5 NPT, 2.5 NPT and 4
inch bolt circle flange versions are available.  When mounted in place of a Qualitrol Rapid
Pressure Rise Relay the hydrogen monitor includes a remote pressure output option.

NOTE:

Sensors are calibrated to be located in either the oil or gas space and can not be

interchanged. An oil sensor must stay in the oil and a gas sensor must remain in
the gas space.

NOTE:

When first applying power to the hydrogen sensors it may take up to 20 minutes for
the sensors to stabilize and begin giving valid hydrogen readings to the 509ITM. In
the meanwhile the 509ITM will display ‘Invalid Reading’ on the local LCD and
transmit a value of zero over the communications protocols.
