Insta-Trace Micro-fuel Oxygen Sensor

Published on : Tuesday 30-11--0001

When a typical electrochemical trace oxygen sensor is removed from its barrier bag for the purpose of replacing an expired sensor, it is exposed to ambient air (209,000 ppm O2).

During this transition from an oxygen free environment to open exposure, the sensor's electrolyte becomes saturated with dissolved oxygen -- and the longer the exposure, the longer the recovery time. The typical recovery period when replacing a sensor is between 6 to 24 hours.

The Insta Trace Micro-fuel Cell oxygen sensor is capable of measuring below 1 ppm of oxygen within 15 minutes of installation. By reducing the recovery period from several hours to just minutes, users will no longer have to divert unanalyzed product, go to liquid back-up (in the case of the air separation industry), or switch analyzers. The intrinsic value of this innovation has extreme significance in plant operation.

Where can Insta Trace be applied?

Teledyne can retrofit Insta Trace sensing capability into all of its Micro-fuel Cell based trace oxygen analyzers currently in service. The retrofit kit contains the cell holder in addition to the Insta Trace sensor. Simply replace the old cell holder (the bottom piece that either threads or mechanically clamps to the cell block assembly) and install the Insta Trace sensor. Take advantage of this innovation by ordering the appropriate retrofit kit.

It is used in Chemical Industries.
