Description The Stanmar Electrical Resistance Unit Probe fitted with the SM-49-PG packing gland is a retractable probe designed for refinery on-line installation at pressures upo to 2000 PSI*. The wide variety of probe sensing elements provide accurate corrosion measurements over a wide range of corrosive environments.
*Pressure rating is dependent upon mounting configuration required. (ex: Flange rating)
The Stanmar High Pressure Retractable Unit Probe provides flexibility and economic replacement via probe inserts. The Wire loop and Tube Loop probes provide the added durability of glass sealed element (in most applications). Alloys and element styles normally available . Other alloys or element styles may be available subject to material.
These probes may be used up to their design temperature and pressure in organic or inorganic fluids of all types, in the pH range of 0-9 or for extremely aggressive service, cylindrical element probes are recommended. In applications where stainle4ss steel bodies would be subject to failure due to stress cracking or pitting, or for probes made of special materials, contact the factory for specific information before ordering.
TEMPERATURE READING OPTION
Temperature is one of the most important controllable factors affection corrosion rate, especially in refineries, rule, the corrosion rate doubles for each 10º C temp. rise. The ability to track temperature and corrosion rate simultaneously is an exceptional tool in the corrosion management of such plants. The Stanmar temperature reading Probe (patented) allows for metal loss and temp. info. to be collected without spending time searching for separate temperature measurement that may not exist for the area you want to monitor. To read these probes you simply need to purchase a 6 pin to 7 pin adapter (p/n: SM-67-cp) and a temperature reading instrument (p/n: SM-7t-tm).
