Abstract:
1. A guided microwave spectroscopy system, comprising: (A) a cylindrical measurement cell, the cylindrical measurement cell comprising: (B) a first microwave probe for radiating electromagnetic energy into the cylindrical measurement cell; (C) a second microwave probe for intercepting electromagnetic energy from within the cylindrical measurement cell; and (D) a path separator, the path separator causing a first portion of the product stream to pass completely through the cylindrical measurement cell and causing a second portion of the product stream to completely bypass the cylindrical measurement cell; (E) a substantially cylindrical outer casing forming part of the cylindrical measurement cell, the cylindrical outer casing comprising at least one orifice, the orifice being formed in the outer casing at a location outside of the waveguide region; (F) a telemetry sensor, the telemetry sensor being introduced into an interior region of the cylindrical measurement cell by extending through the orifice formed in the outer casing of the cylindrical measurement cell; (G) a first probe port, the first probe port being formed in the outer casing, the first probe port residing between the first and second plate so as to permit the first microwave probe to launch electromagnetic energy into the waveguide region, the first probe port having a fixed width and defining a first substantially rectangular plane, the first probe port having a leading edge, the first substantially rectangular plane being substantially perpendicular to the first plate and to the second plate; (H) a second probe port, the second probe port being formed in the outer casing, the second probe port residing between the first and second plate so as to permit the second microwave probe to intercept electromagnetic energy launched by the first microwave probe into the waveguide region, the second probe port having a trailing edge, the second probe port being longitudinally offset from the first probe port such that a distance between the leading edge of the first probe port and the trailing edge of the second probe port is at least twice as great as the fixed width of the first probe port.
