Dual Sensor Electrical Resistance (ER) Temperature Probes

Temperature is one of the most important controllable factors affecting corrosion rate, particularly in refineries, chemical, and petrochemical process plants. A rule of thumb is that corrosion rates double for each 10 degrees C temperature rise. The ability to track temperature and corrosion rates simultaneously is a powerful tool in the corrosion management of such plants.

Electrical Resistance (ER) Probe Accessories

Electrical Resistance and ER Temperature probes are designed for safe installation and operation in various environments. Certain accessories are required based on pressure, temperature, etc.

ER Fixed Flush Element Probe 2700/2705

Model 2700 and 2705 fixed process probes have a flat strip measuring element sealed and mounted at the end of a heavy walled stainless steel tube. The measuring element can be positioned flush with the inner surface of the pipe or vessel. Corrosion or erosion can then be measured right at this surface, and the lines may be pigged without moving the probes.

Fixed Process Electrical Resistance (ER) Probe 2500/2500HT

Model 2500 fixed process probes have a thin walled cylindrical sensing element which is welded onto a body of the same material. No other materials are in contact with the corrosive medium. Welds are vacuum annealed during assembly to avoid preferential corrosion effects.

Fixed Process Electrical Resistance (ER) Probe 2520/2520HT

Model 2520 fixed process probes are designed for particularly severe or toxic duty service, where retractable or fixed thread probes are not permitted by plant or other regulations.

Heavy Duty Underground Electrical Resistance (ER) Probes 620HD/650

Model 620HD and 650 ER probes are designed for underground and structural monitoring of pipelines, vessels, above and below ground storage tanks and structures — whether cathodically protected or not.

High Pressure Bio-Probe 6205

Cosasco Bio-Probes for the 2″ system are used to suspend sample elements in the area to be monitored. Attached to the bottom of the solid plug by means of a left handed thread, the bio-probe also serves as a primary packing retainer.

High Pressure Linear Polarization Resistance (LPR) Probe 6080

This probe employs two identical electrodes which are mounted at the end of the probe by threaded, insulated, glass-sealed studs. The glass seals provide high pressure integrity. The probe is sealed into the hollow plug of the access fitting with a ceramic filled teflon seal.

Linear Polarization Resistance (LPR) Probe Accessories

LPR and Temperature LPR probes are designed for safe installation and operation in various environments. Where danger of blowout exists, use of an appropriate safety device should be considered mandatory. This equipment is designed and tested for reliability, using established principles of operation.

LPR Probe 6112

This LPR probe model is ideally suited for laboratory testing or light duty plant operations in a bypass rack where removal under system pressure is not required. For heavier duty plant operation see Model 7012 or 7022.

LPR Probe 7012/7022

The Model 7012/7022 LPR Probe provides a more rugged construction and is ideal for plant use in a bypass rack where removal under pressure is not required. This LPR probe employs two replaceable, identical electrodes which are mounted at the end of the probe by threaded, insulated studs.

LPR Probe 7212/7222

This probe employs two identical electrodes which are mounted at the end of the probe by threaded, insulated studs. The glass reinforced epoxy electrode header used on the Model 7212 provides insulation and is preferred at high pH ranges over the glass sealed Model 7222.

Microcor® High-Sensitivity Erosion Probes

Cosasco offers a range of metal loss sensors and instrumentation, designed specifically to detect sand erosion at speeds approaching real-time. Sensing elements for the erosion/corrosion measurement system can be made from almost any commercially available, alloy.

Microcor® High-Speed ER Corrosion Probes

Microcor® ER Probes are an integral component of the new high-resolution Microcor® system. Special design of the probes provides advanced thermal performance and reliable operation in all environments including sour service.

Retractable Electrical Resistance (ER) Probe 3500 & 3500HT

Model 3500 Probes provide a large test surface, excellent dynamic temperature response and protection of reference element.They are ideally suited to the more aggressive plant conditions and may be used in very aggressive organic or inorganic fluids over the entire pH range 0-14, subject to process containment requirements.

Retractable Element Electrical Resistance (ER) Probe 3520 & 3520HT

Model 3520 retractable process probes are designed for particularly severe or toxic duty service, where fixed thread probes are not permitted by plant or other regulations.

Retractable Flush Electrical Resistance (ER) Probe 3700/3705

Model 3700 and 3705 retractable process probes have a flat strip measuring element sealed and mounted at the end of a heavy walled stainless steel tube. By adjusting the position of the probe or proper selection of the physical dimensions of the coupling system, the measuring element can be positioned flush with the inner surface of the pipe or vessel.

Retractable Linear Polarization Resistance (LPR) Probe 8012/8022

These Models are ideal for direct mounting into plant pipework or vessels and allow insertion or removal while under system pressure. The electrode seals are suitable for all pH ranges. These probes employ two replaceable, identical electrodes which are mounted at the end of the probe by threaded, insulated studs.

Retractable Small Diameter Electrical Resistance (ER) Probe 3504/3504HT

Model 3504 Retractable Process Probes are ideally suited to the more aggressive plant conditions and may be used in very aggressive organic or inorganic fluids over the entire pH range 0-14, subject to process containment requirements. These probes are standard in mild steel, 304 S.S. and 316 S.S..

Retrievable Fixed and Adjustable ER Probe 4700,4700-ADJ

Model 4700 probe is available with a durable construction incorporating a connector with shrouded pins to prevent accidental damage. This high pressure probe with element thicknesses up to 40 mils, can be read by any Electrical Resistance (ER) corrosion monitoring instrument.

Retrievable Flush Element Electrical Resistance (ER) Probe 4705

Model 4705 probe is available with a durable construction incorporating a connector with shrouded pins to prevent accident damage. It is recommended for all new installations. This new style incorporates welded shields where required and requires a different probe connecting adaptor (see order details).

Retrievable Process Electrical Resistance (ER) Probe 4500

Model 4500 probe is available with a durable construction and incorporating a connector with shrouded pins to prevent accidental damage. It is recommended for all new installations. This new style incorporates welded shields where required and requires a different probe connecting adaptor (see order details).

Sand Probe Erosion Detection System

Sand production in oil and gas producing wells can cause rapid erosion and wear of top side equipment such as chokes, valves, and flow-lines. The areas that can experience the most severe effects of erosion are immediately downstream of a choke, outer diameters of bends, reducers, misaligned flange joints and pipe T joints.
