Patent number: 7259952Abstract: A process control instrument includes a circuit board having a control circuit for generating or receiving a high frequency signal. An antenna includes an electrical conductor. An intrinsic safety circuit couples the control circuit to the antenna and comprises a microstrip transmission line on the circuit board electrically connecting the control circuit to the electrical conductor. A safety stub has a first end electrically connected to the transmission line proximate the electrical conductor and a second end connected to a ground of the control circuit.Type: GrantFiled: October 4, 2005Date of Patent: August 21, 2007Assignee: Magnetrol International, Inc.Inventors: Michael D. Flasza, Stanislaw Bleszynski

Patent number: 7106248Abstract: A process control instrument comprises a control for generating or receiving a high frequency signal. A waveguide comprises a cylindrical housing closed at one end by a rear wall. A loop launcher is operatively connected to the control and comprises a wire having a first straight leg electrically connected at one end to the control and extending into the waveguide a first select length. A second straight leg is connected at one end to the rear wall and extends into the waveguide a second select length, greater than the first select length. A curved middle section connects the other ends of the first and second straight legs. An antenna is operatively coupled to the waveguide.Type: GrantFiled: August 16, 2005Date of Patent: September 12, 2006Assignee: Magnetrol International, Inc.Inventors: Paul G. Janitch, John S. Benway, Stephen A. Reynolds, Stanislaw Bleszynski

Patent number: 5943294Abstract: A vibrating probe for detecting a threshold level within a vessel of fluent material, particularly a liquid, includes: an ultrasonic acoustic transducer assembly comprising a transducer element having a natural resonant frequency, and loading elements effective to shift that frequency to an effective resonant frequency of the assembly, the assembly being supported within the vessel and including a coupling member to couple the transducer acoustically to liquid reaching the threshold level, a transmitter generating pulses applied to the transducer element for repeatedly exciting the transducer element to cause the transducer assembly to resonate at its effective resonant frequency, a circuit for measuring the effective resonant frequency of the transducer over a ringdown period following cessation of each pulse, and a circuit for comparing the effective resonant frequency measured during the ringdown period following each pulse with a predetermined threshold level.Type: GrantFiled: May 1, 1998Date of Patent: August 24, 1999Assignee: Milltronics Ltd.Inventors: Bogdan Cherek, Stanislaw Bleszynski
