Abstract:
An in situ flue gas analyzer includes a probe extendable into a flue. The probe has a measurement cell providing a signal responsive to a concentration of a gas within the flue. A controller is coupled to the probe and configured to provide an output based on the signal from the measurement cell. A first media access unit is coupled to the controller and is operably coupleable to a first process communication link. The first media access unit is configured to communicate in accordance with an all-digital process communication protocol. A second media access unit is coupled to the controller and is operably coupleable to a second process communication link. The second media access unit is configured to communicate in accordance with a second process communication protocol that is different than the all-digital process communication protocol. The first and second media access units are enabled simultaneously.
Abstract:
A process analytic device has an input to receive a sample of interest. An analytic detector is operably coupled to receive the sample of interest and to provide an analytic output relative to the sample of interest. A heat pipe is thermally coupled to the analytic detector. In one embodiment, the process analytic device is a process gas chromatograph.
Abstract:
A planar manifold includes a first, generally planar, layer having a plurality of apertures therethrough. A second layer has a plurality of apertures therethrough. A channel layer defines a plurality of channels therein and is interposed between the first layer and the second layer. At least one channel extends in a direction parallel to a plane of the planar manifold and couples an aperture of the first layer to an aperture of the second layer.
Abstract:
A gas analyzer includes a sample inlet, a sample outlet, a detector, a monitoring component, and a controller. The sample inlet is configured to receive a sample and is coupled to the sample outlet. The detector is operably disposed between the sample inlet and the sample outlet and is configured to provide an indication relative to the sample. The monitoring component is configured to provide a diagnostic indication regarding at least one component of the gas analyzer. The controller is configured to control flow through the gas analyzer and is operably coupled to the detector to analyze the sample, provide the analysis to the monitoring component, and provide the indication of health to an output.
Abstract:
A process combustion transmitter is provided. The transmitter includes a process probe extendible into a flow of process combustion exhaust. The process probe has a measurement cell with an operating temperature that is above a flashpoint of process combustion fuel. The process probe includes a heater configured to heat the measurement cell to the operating temperature. Electronic circuitry is coupled to the measurement cell and to the heater. The electronic circuitry is configured to disengage power to the heater once process combustion heat is sufficient to maintain the measurement cell at the operating temperature and thereafter to maintain the heater in a de-energized state.
Abstract:
A calibration solution for a wet chemistry analyzer is provided. The solution comprises a calibration agent. The solution also comprises a cleaning agent. The cleaning agent is selected such that the wet chemistry analyzer is simultaneously cleaned and calibrated.
Abstract:
A bioreactor sensing system is presented. The bioreactor sensing system comprises a bioreaction vessel. The bioreaction vessel comprises an aperture configured to provide an interface for monitoring contents within the bioreaction vessel. The bioreaction vessel also comprises a port coupled to the bioreaction vessel proximate the aperture. The bioreactor sensing system also comprises a sensing device disposed at least partially within the port such that a sensing element is exposed to the contents. The bioreactor sensing system also comprises an external seal configured to be applied over a portion of the sensing device and a portion of the port.
Abstract:
An in situ oxygen analyzer having an intrinsically-safe output and a heated probe is provided. The probe is extendable into a source of process gas and has an oxygen sensor and heater disposed therein. The heater is configured to heat the oxygen sensor to a temperature sufficient to operate the oxygen sensor. A housing is coupled to the probe and has first and second chambers. The first chamber is explosion-rated and includes non-intrinsically safe circuitry coupled to the heater to energize the heater. The second chamber contains only intrinsically-safe circuitry that complies with an intrinsically-safe specification. The first and second chambers are isolated from one another. The non-intrinsically-safe circuitry is coupled to the intrinsically-safe circuitry through an energy-limiting isolator.
Abstract:
A single use pH sensor housing for a single use container is provided. The single use pH sensor housing includes a compartment configured to house a single use pH sensor. In one embodiment, the single use pH sensor housing comprises an actuator configured, when actuated, to transition the single use pH sensor from a storage position to a deployed position. In the storage position, the pH sensor is in fluidic contact with a buffer solution. In the deployed position, the single use pH sensor is in fluidic contact with an interior of the single use container. During the transition from the storage position to the deployed position, the buffer solution moves from a sensor portion of the compartment to a storage portion of the compartment such that the buffer solution is isolated from contact with the interior of the single use container.
