Fixed Electrical Resistance Corrosion Probes

DESCRIPTIONStanmar Fixed Electrical Resistance Corrosion Probes are designed for services where retractable probes are not permitted by plant or other requlations. they use the same principals of monitoring corrosion rates as the retractable versions but in addition they provide a more economic approach and in most cases a higher temperature and pressure rating than retractable probes. Stanmar Fixed Probes are not removable under system pressure. 

Fixed Corrosion Probes are available with wire loop, tube loop, and cylindrical sensing elements. Glass sealed elements provide the wire loop and tube loop series of probes increased protection for the reference element. Designed with rugged fixed boddies, these probes are an excellent choice when optimizing your corrosion monitoring/control program. These probes are designed for organic or inorganic fluids of all types in the pH range of 0 to 9. Cylindrical element probes are recommended for more aggresive enviroments. The all welded construction of a cylindrical element provides the highest integrity for a corrosion measurement element. Only the material under evaluation is exposed to the process fluid.

Fixed probes are available with mounting options of NPT threaded or flanged. If you have a special mounting configuration that does not fall into these categories, consult the factory for custom mounting options. Standard body material is stainless steel. In applications where steel bodies would be subject to failure due to stress cracking or pitting, or for probes made of special material, contact the factory for specific information before ordering. High temperature versions of these probes are available. Maximum temperature and pressure of Stanmar Fixed Probes are frequently limited by flange ratings rather than probe construction.

In cases of the more exotic alloys such as Hastelloy, Monel, Incalloy, Titanium or other alloys where materials and flanges are relatively expensive, refurbishing of the process side of the quill may be possible at the end of probe element life.

  

 

TEMPERATURE READING OPTION

The same temperature reading option that is available with the Stanmar Retractable Corrosion Probes is available in the fixed probes also.

WARRANTY STATEMENT

Stanmar Fixed Corrosion Probes are custom designed to meet your corrosion monitoring needs. Sensor readings, check readings, and installation instruction accompany each shipment. Failure to comply with these instructions may inhibit corrosion coupon performance. Warranty allowance is at the discretion of the manufacturer.
