  • Patent number: 11137361
    Abstract: An industrial process vessel insulation monitoring system for monitoring an insulated section of a process vessel containing a process material includes one or more condition sensors and a controller. The condition sensors are configured to sense at least one environmental condition, such as temperature, humidity, moisture level, and/or chemical composition, and generate condition outputs that are indicative of the corresponding sensed condition. The controller is configured to detect at least one section condition relating to the insulated section based on the condition output, and generate condition information relating to the at least one detected section condition. Examples of the section conditions include a thermal resistance of an insulation of the insulated section, damage or degradation to an insulation of the insulated section, corrosion of the process vessel at the insulated section, conditions that promote corrosion of the process vessel, and moisture intrusion to the insulation.

  • Patent number: 10641412
    Abstract: A steam trap monitor includes a process variable sensor configured to sense a process variable related to operation of a steam trap. A memory contains information related to a baseline parameter of the process variable. Diagnostic circuitry calculates a current parameter of the process variable sensed by the process variable sensor and compares the current parameter of the process variable with the baseline parameter. Based on the comparison, the diagnostic circuitry responsively provides a diagnostic output based upon the comparison. The baseline and current parameter are based on a time period during which the steam trap is open or closed.

  • Patent number: 10153898
    Abstract: A wireless mesh network provides secure communication by encrypting data using one or more encryption keys. A configuration device in communication with a security manager of the network provides a temporary secure communication path between the security manager and a new field device to be added to the mesh network. Cryptographic material and other configuration data can then be transferred between the security manager of the network and the new field device securely via the configuration device.

  • Patent number: 9454744
    Abstract: An asset tracking system for use in a process control environment may include one or more asset tracking devices and an asset tracking host. The asset tracking device may receive signals corresponding to a position or location of an asset to be tracked, and may communicate, using an industrial automation protocol such as wireless HART, an indication of the position to the asset tracking host. The signals may be GPS signals that are re-radiated into the process control environment. Other information, such as environmental data, may be communicated in conjunction with the position of the asset. The asset tracking host may store and/or display the data or information included in the message, and may send a different message to the asset tracking device. An asset tracking device may be included in a field device, a network device, or a portable communications device used in the process control environment.

  • Patent number: 8719327
    Abstract: A method and device or monitoring parameters in a process reduces power consumption and bandwidth requirements in the transmission of the monitored parameter to for example, a monitoring application. In particular, new monitoring parameter values are only transmitted if the difference between a measured or calculated parameter value and the most recently transmitted value exceeds a limit, since the last communication of the parameter or if the time since the last communication of the parameter exceeds a preset refresh period. The determination as to whether to transmit the parameter can be applied to engineering unit values or raw values.
