InsuLogix™ H Hydrogen Detector

Proven and Accurate Technology

The Weidmann InsuLogix™ H Hydrogen Detector employs proven thermal conductivity technology (TCD) with a measurement range of 0-10% H2.  The InsuLogix™ H Low Detection Limit (LDL) is equivalent to 50 PPM H2 in oil (or 1000 PPM in transformer headspace).

Benefits

• Designed for Nitrogen headspace applications
• Robust and tested technology platform
• Easy field installation, no transformer outage required
• Simple set-up and operation, no need for computer
• The only fault detector that can be easily calibrated in field using standard gas
• Responds to utilities’ demand for an economically priced H2 monitor
• Adjustable H2 alarm set-points correlated to IEEE C57.104 headspace gas
• Prepared for remote sampling interval modulation (manual or automatic) 

Features

• Capable of detecting H2 levels as low as ~50ppm in oil equivalent (1000ppm H2 in headspace)
• User selectable test intervals
• Two H2 alarm levels, one solid state relay
• Manual alarm reset at unit
• One 4-20mA output (H2)
• Failure watchdog
• Minimum and maximum H2 values retained
• Backflow check valve in exhaust prevents contamination ingress under vacuum
• Pure Nitrogen is used to set the detector’s baseline before each test
• Optional: 4-20mA output recorder, USB memory stick
• Optional: 4-20mA signal conversion and two way wireless data transmission, the information being visualized over secure Internet connection starting with satellite maps view of all substations equipped with InsuLogix H and scaling down to each monitor to see the status, the H2 trend, change the sampling interval or remotely force a test.
