MCG 8190A Rigid Magnetostrictive Level Probe with Pressure Sensor

An Integrated Approach
The MCG 8190A Rigid Magnetostrictive Level Probe is a highly accurate, continuous measurement device that is easy to install and maintain. The compact design allows for the collection and transmission of an impressive amount of data. In addition to measuring two levels (product and interface or two interfaces), five (5) temperature sensors are embedded in the probe at different levels to provide average temperature measurement of the product.

Density Calculation
The MCG 8190A is a specialized version of the MCG 8150B, adding the ability to measure the density of the stored product and use this information to accurately calculate corrected volume. The density measurement is gathered by a pressure sensor mounted directly to the stainless steel housing of the probe itself. The collected data is then analyzed to provide the most comprehensive and accurate measurement available.

Proven Technology
The magnetostrictive technology that is employed in the MCG 8190A has been proven to be extremely reliable. The probe is comprised of a wave guide, one or two floats with permanently-embedded magnets, a motion or stress sensing device, and a probe housing. Together, these components measure the level of product in a vessel through a simple physical property known as the Wiedemann Effect.

With rigid probes available in lengths up to 24 feet (7.2 m), the MCG 8190A probe can be installed in nearly any type of storage or process vessel; aboveground or underground. Standard Mounting Options can accommodate 2″, 3″, and 4″ openings. Flanged connections are also available.

Level Measurement and Point Switch…All in One
Because of the probe’s packaging and its high degree of resolution (+/- .001″), the MCG 8190A can provide both level gauging data and act as a point switch for process vessels or overspill alarms.
