    Abstract: A field device mount includes a union configured to couple to a field device. A clamp foot is coupled to the union and is configured to engage fluid handling equipment. A tensioner assembly is coupled to the clamp foot and includes a tensioner bracket. A biasing member is disposed to urge the tensioner bracket away from the clamp foot. A band is configured to pass around the fluid handling equipment and to couple to opposite sides of the tensioner bracket. A buckle is configured to provide clamping force to maintain tension in the band. A field device mount using inline tensioners or a v-bolt as well as a method of coupling a field device mount to fluid handling equipment are also provided.

    Abstract: A process oxygen analyzer includes a process probe extendible into a flow of process combustion exhaust, the process probe having an oxygen sensor measurement cell. Measurement circuitry is coupled to the oxygen sensor measurement cell and configured to obtain a non-corrected indication of oxygen concentration relative to a combustion process based on an electrical characteristic of the oxygen sensor measurement cell. A controller is operably coupled to the measurement circuitry and is configured to obtain an indication of process pressure and selectively provide a corrected oxygen concentration output based on non-corrected indication of oxygen concentration and the indication of process pressure. A method of providing a process oxygen concentration using a process oxygen analyzer coupled to an industrial combustion process is also disclosed.

    Abstract: A process temperature estimation system includes a mounting assembly configured to mount the process fluid temperature estimation system to an external surface of a process fluid conduit. A hot end thermocouple is thermally coupled to the external surface of the process fluid conduit. A resistance temperature device (RTD) is spaced from the hot end thermocouple. Measurement circuitry is coupled to the hot end thermocouple and is configured to detect an emf of the hot end thermocouple and a resistance of the RTD that varies with temperature and provide sensor temperature information. A controller is coupled to the measurement circuitry and is configured to measure a reference temperature based on the resistance of the RTD and employ a heat transfer calculation with the reference temperature, the emf of the hot end thermocouple, and known thermal conductivity of the process fluid conduit to generate an estimated process temperature output.

    Abstract: A pH sensor for a single-use container includes a plunger sleeve configured to couple to a flange of the single-use container. A plunger is axially movable within the plunger sleeve between a storage position and an operating position. A pH sensing element coupled to the plunger wherein the pH element is disposed within a storage chamber in the storage position and is configured to be exposed to an interior of the single-use container in the operating position. In one example, a temperature sensitive element is disposed within the pH sensor and configured to sense temperature proximate the pH sensing element. In another example, a lock member is coupled to the plunger, where the lock member has a locked position and an unlocked position, the lock member being configured to inhibit movement of the plunger when in the locked position. In yet another example, the plunger includes at least one filling channel that allows access to a reference fill chamber when the plunger is in a filling position.

    Abstract: An industrial process field device includes an active component, a switch, a switch monitor, and a controller. The active component may be a sensor configured to sense a process parameter, or a control device configured to control a process of the industrial process. The switch is electrically coupled to first and second terminals. The switch monitor is configured to detect an open or closed state of the switch, and generate a first state output, a second state output, or a chattering state output. An anti-chatter circuit outputs a chatter stabilized state output based on the chattering state output. The controller is configured to set the switch in the open or closed state, and generate a notification based on any one of the first and second state outputs and the chatter stabilized state output that indicates at least one of the current state and a condition of the switch.

    Abstract: A process fluid temperature estimation system includes a mounting assembly configured to mount the process fluid temperature estimation system to an external surface of a process fluid conduit. A sensor capsule has at least one temperature sensitive element disposed therein and is configured to sense at least a temperature of the external surface of the process fluid conduit. Measurement circuitry is coupled to the sensor capsule and is configured to detect a characteristic of the at least one temperature sensitive element that varies with temperature and provide sensor capsule temperature information. A controller is coupled to the measurement circuitry and is configured to obtain a temperature measurement of the external surface of the process fluid conduit and to obtain a reference temperature and employ a heat transfer calculation with the reference temperature, the external surface temperature measurement and a known thermal relationship between the external surface temperature sensor in the sensor capsule and the reference temperature to generate an estimated process fluid temperature output. The controller is also configured to improve response time of the process fluid estimation system mathematically. In some examples, the controller is configured to extract the system tau value from the measured data.
