Abstract: A microwave resonator flame ionization detector assembly includes a microwave resonator disposed proximate a flame to evaluate an ion concentration in a flame effluent. A resonant frequency of the microwave resonator is detected, and a reflection coefficient of the resonator is used to determine an electric permittivity of a material in which the resonator is immersed. The electric permittivity depends on an ion concentration proximal to the resonator, and the ion concentration is related to the concentration of hydrocarbons present in the flame.

Abstract: An interface for coupling a dissolved oxygen sensor to a single-use bioreactor container is provided. A dissolved oxygen (DO) window membrane is operably coupled to the single-use container and configured to position a DO sensor at least partially within the single-use container. In some embodiments, a DO window body mounts the DO window membrane at a distal end thereof. The DO window body can include a slide lock for facilitating positioning of a DO sensor within the DO window body. Additionally, the DO window body may include at least one heat exchange fin.

Abstract: A process variable transmitter for use in an industrial process includes a housing having a cavity formed therein. The housing has a barrier which divides the cavity into first and second cavities. Measurement circuitry in the first cavity is configured to measure a process variable of the industrial process. A terminal block assembly is located in the second cavity. A moisture sensor has an electrical characteristic which changes based upon the presence of moisture in the second cavity.

Abstract: A two-wire process variable transmitter for use in an industrial process includes a process variable sensor configured to sense a process variable of a process fluid of the industrial process. Output circuitry provides an output on a two-wire process control loop which is related to the sensed process variable. Terminal voltage measurement circuitry measures a voltage at terminals of the process variable transmitter. The terminal voltage is a voltage measured across an electrical connection of the two-wire process variable transmitter to the two-wire process control loop. A microprocessor performs loop diagnostics on the two-wire process control loop based upon a loop current and the measured terminal voltage. The microprocessor determines coefficients of a polynomial equation which relates loop current and terminal voltage during normal operation of the two-wire process variable transmitter and performs subsequent diagnostics based upon the coefficients of the polynomial.

Abstract: An electronics package includes a platform and a board mounted to the platform, the board having electronics mounted thereon. A feedthrough pin passes through and is hermetically sealed to a feedthrough body and is wire bonded to the board. A cover is bonded to and surrounds the exterior surface of the feedthrough body to produce a hermetically sealed chamber that houses the platform and the board.
