Electrical Resistance Probe
Electrical Resistance (ER) probe and electrical equipment are basically "automatic coupons" and have much in common with corrosion coupons. Electrical resistance systems work based on measuring the electrical resistance of a thin metal element. As the metal corrodes and becomes corroded, its resistance increases. The most important advantage of the electrical resistance method over coupons is the ability to perform more and simpler measurements. In automated systems, continuous corrosion monitoring and advanced analysis methods allow detection of corrosion rate changes in just a few hours. Using this information, it is possible to timely modify the chemicals and process conditions.
Borna Electronics has the ability to manufacture ER probes for internal corrosion monitoring as well as soil probes for cathodic protection monitoring. These probes divided in three categories: fixed, retrievable and underground.
Standard material of probe body is stainless steel AISI 316L meets ANSI / NACE MR0175 / ISO 15156 standard for sour environments. For environments with extremely severe corrosive conditions, alternatives suitable for those environments can be used. The probe sensor elements are designed and manufactured in a variety of flush, cylindrical and tubular types.
To order the desired probe the corresponding code is obtained according to the probe specifications and the following table:
