The Onyx Isolator Ring can be used in a wide variety of industries, such as chemical, food & beverage, mining, pulp & paper and wastewater treatment. Typical applications include:

• line pressure measurement of slurries, corrosives and difficult fluids
• tank level indication
• monitoring pressure on long distance transmission lines to detect line breakage
• monitoring pressure drops across a filter or pump using two pressure sensors with a differential pressure switch
• measuring the output pressure of a pump
• sending a signal to stop a pump or open a by-pass valve

Proven Benefits

• Gauges can be removed or replaced without interrupting process
• Gauges can be replaced without vacuum filling
• No tools required to change pressure instrument (simply remove and replace by turning the knurled collar)
• No snubber required (needle functions as built-in snubber)
• Improved safety (process liquid cannot escape if gauge is removed, even if process pipe is under pressure)
• High accuracy (because air can never get into the system)
• No isolation valve required
• Gauges can be rotated by hand to face any direction
• Isolation rings and gauges can be stocked separately (combine as needed on the spot)
• Sturdy mounting for heavy gauges and multiple instruments (robust 0.87" dia. mounting post resists breakage; up to three gauges, pressure switches and transmitters can be combined on one isolator without additional support)
