摘要： A calibration device for a conductivity sensor for aqueous solutions. The calibration device includes a first connector configured to electrically couple with the sensor electrodes of the conductivity sensor. The connector is further configured to provide for the application of a controlled voltage across at least two of the sensor electrodes. A first resistor is connected between the at least two sensor electrodes and coupled to the first connector. The resistor has a value such that a current flow between the at least two sensor electrodes replicates the properties of an electrochemical calibration solution. In certain embodiments, the calibration device is configured for pH sensors or dissolved oxygen sensors.

摘要： A flange-mounted inline valve arrangement includes a flange having an internal fluid passage, and an inline electrically-operable valve coupled to the flange. The inline valve includes a valve body and a valve member movable relative to the fluid passage in the flange for controlling flow. The valve arrangement also includes an electrical feed that connects to the electrically-operable valve through the flange for enabling an electrical connection external to the flange and other system piping. At least part of the electrical feed may be in a flow path and is fluidly sealed to prevent electrical shorts. The valve arrangement may be installed into the system as a single unit with an exterior coupling of the electrical feed on an exterior part of the flange to easily make the external electrical connection. The valve arrangement may be used in a chiller, where the inline valve is an electronic expansion valve.

摘要： Disposable, pre-sterilized, and pre-calibrated, pre-validated sensor components are provided. The sensor components interact with a sensor system having disposable fluid conduit or bioreactor bag and a reusable sensor assembly. The components can include an optical bench or inset optical component or module designed to be integrated within the disposable fluid conduit or bioreactor bag, which provides an optical light path through the conduit or bag. The sensors systems are designed to store sensor-specific information, such as calibration and production information, in a non-volatile memory chip on the disposable fluid conduit or bag and on the reusable sensor assembly. Methods for calibrating the sensor and for determining a target property of an unknown fluid are also disclosed. The devices, systems and methods relating to the sensor are suitable for and can be outfitted for turbidity sensing.

摘要： A vehicle includes at least one wheel hub, a wheel hub speed sensor, and a controller. The wheel hub is configured to be coupled to a drive wheel. The wheel hub speed sensor is proximate to the wheel hub and is configured to generate a wheel hub speed signal that facilitates determination of a rate and direction of rotation of the wheel hub. The controller is configured to communicate power to a motor assembly coupled to the wheel hub to rotate the wheel hub at a particular rate and in a particular direction. The particular rate and the particular direction are associated with a particular position of a plurality of positions of a steering control.

摘要： A filter system comprises a pressure vessel housing with internal components designed to remove solid particles, semi-solid particles, and liquid droplets from a gas phase media. The filter housing utilizes multiple replaceable filter cartridges. The system includes a keyed filter coalescer cartridge designed to flow from the inside open area of the cartridge to the outside annular area of the housing prior to leaving the system through an outlet nozzle. The key is designed to locate a baffle of the filter cartridge inlet side end cap in a certain orientation as to provide enhanced liquid removal performance for the system. The baffle may also serve as a handle.

摘要： A fitting assembly includes an indicator assembly that provides a visual indication of torque value to verify when the desired operational torque value is achieved. The fitting assembly includes a nut, and a visual indicator assembly positioned on the nut which has a plurality of visual indicators that provide a visual indication of a torque level being applied. A sleeve is attached to the nut and includes a window through which a portion of the visual indicators is visible based on the torque level being applied. A resilient member couples the sleeve to the nut. As the nut is rotated to apply torque to the nut, the resilient member biases the sleeve in a fixed position and the nut rotates relative to the sleeve, whereby the visual indicator assembly rotates relative to the sleeve to alter which portion of the visual indicator assembly is visible through the window to provide a visual indication of when the operational torque level is being applied. The fitting assembly includes a positive locking feature that interacts with a serrated portion of a nipple fluid connection to positively lock a position of the nut to prevent nut loosening.

摘要： A coupling assembly (10) is reconfigurable among three states. In a disconnected state, a spring-biased lock indicator (20) is in a first lock indicator position, and the lock indicator includes a restriction member (40) that in the first lock indicator position retains an actuator in a first actuator position such that a valve is in a closed position and a locking pin is in a retracted position. In a connected/valve-closed state, the lock indicator (20) is in a second lock indicator position in which the restriction member (40) permits movement of the actuator (30), but with the actuator (30) still being in the first actuator position such that the valve is in the closed position and the locking pin (46) is in the retracted position. In a connected/valve-open state, the lock indicator (20) is in the second lock indicator position to permit movement of the actuator (30), and now with the actuator (30) being in the second actuator position such that the valve is in the open position and the locking pin (46) is in an extended position to lock a second coupling assembly to the coupling assembly to form a unisex coupling connection.

摘要： A coupling member for a blind mate fluid coupling includes a housing and a fluid connector fixed in position relative to the housing for connecting to a fluid conduit of the system. A valve body extends through the housing and is movable relative to the housing. The valve body includes an internal fluid passage that is fluidly connected to the connector, and a valve member opens or closes the internal fluid passage. A carrier is at least partially disposed in the housing and is radially movable relative to the housing. The carrier is configured to cooperate with the valve body to facilitate alignment of the valve body when coupling to another coupling member. The carrier may form a portion of the fluid passage between the connector and valve body, and includes a sealing arrangement that permits radial and/or angular misalignment compensation of the design. Varying diameters of the insertion part or receiving part of the coupling member may be provided for further enhancing misalignment compensation of the design.
