MCG 8140 Wireless Magnetostrictive Level Probe

An Integrated Approach
The MCG 8140 Wireless Magnetostrictive Level Probe is a highly accurate, continuous measurement device that is easy to install and maintain. The MCG 8140 combines our highly reliable magnetostrictive technology with our wireless Spread Spectrum Technology (frequency hopping) to provide both highly accurate, reliable level data transmission without the need of any power or signal wire. The MCG 8140’s compact design allows for the collection and transmission of an impressive amount of data. In addition to measuring two levels (product and interface), five temperature sensors are embedded in the probe at different levels to provide average temperature measurement of the product. With its flexible probe available in lengths up to 70 feet (15.2 meters), the MCG 8140 Wireless Magnetostrictive Level 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.

Wireless Technology
The MCG 8140 features an integrated radio and antenna design eliminating hardwire cable and conduit connections to the control room. The wireless Spread Spectrum Technology provides a transparent, wireless RF link to the MCG 5102 Wireless Base Station connected to your gauging system of choice such as the MCG 3900 Inventory Management System. The wireless technology is compatible with all existing L&J protocols and many other standard protocols.

Level Measurement & Point Switch…All in One
Because of the probe’s packaging and its high degree of resolution (+/- .001”), the MCG 8140 can provide both level gauging data and act as a point switch for process vessels or overspill alarms.

Standalone/Low Power/Cost Effective
The battery powered operation of the MCG 8140 allows it to act as a standalone, cost effective level gauging solution. If field power to the tank farm were to fail there would be no effect on the MCG 8140 because of this. The power draw of the MCG 8140 is minimal so constant battery changing and servicing is not required.

Proven Technology
The magnetostrictive technology that is employed in the MCG 8140 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.
