High Speed Electrical Resistance
Microcor® Probes are an integral component of the new high-resolution Microcor® system, including the Microcor Wireless Transmitter. Special design of the probes provides advanced thermal performance, and reliable operation in all environments including sour service. Two forms of probe element are available – flush and cylindrical. Several mounting configurations are available, the most common of which allow the probes to be inserted and removed under full process operating conditions without shutdown.
The M2000 series probes are fixed probes that are used in high pressure, or especially hazardous process streams. However, they cannot be removed or replaced without system shutdown, unless installed in a bypass loop.
The M3000 series probes are called retractable probes that can be removed or replaced under full system operating conditions, up to 1500 psi (100 bar) and 425°F (218°C). With high temperature versions this may be extended to 1000°F (520°C) at pressures up to 1000 psi (67 bar). This series uses a sliding stuffing box seal.
The M4000 series probes are called retrievable probes and are designed for use in the Cosasco® high pressure access fitting range. This permits probes to be removed or replaced at process conditions up to 6000 psi (400 bar), and temperatures up to 400°F (204°C) with the Cosasco® Retriever and service valve. Note: All 4000 series probes must be installed with an overshot adaptor (P/N 126292) to maintain connector cleanliness.
