Extractable 1“ - 3/4“ probe
Low pressure ER extractable 1” - 3/4” probe is basically a thin metal probe of different shapes with a well-known electrical resistance.
The material loss due to the corrosive attack causes an increase of resistance measured by the AE-Corr-Ohmeter which is a suitable instrument that gives directly Corrosion Rate, for every time interval (at least in Continuous Mode), without any action on the plant.
ER Probe is composed of a Probe Body of length determined by the process conditions and by a Sensing Element, that could be Wire Loop or Tubular type.
A threaded or flanged Packing Gland is connected to a Ball Valve.
Insertion and extraction can be done without any use of other tools; Safety Clamps can be provided to increase safety.
ER extractable probe could be extracted or inserted while the plant is working.
