Abstract:
A process device for coupling to an industrial process for use in monitoring or controlling the process includes a device housing (16) configured to physically couple to the industrial process. A coil of wire (100) is mounted to the housing and a magnet (104) is configured to move through the coil of wire. The relative movement of the magnet is responsive to vibrations (72) in the industrial process. Such relative movement induces an electrical current. in the coil of wire. Electrical circuitry in the housing includes an input to receive the electrical current from the coil of wire.
Abstract:
A two-wire process transmitter (12) for use in monitoring an industrial process (10) includes HART communication circuitry (82) and Fieldbus communication circuitry (86) to couple to a two-wire process control loop (18). A first pair of electrical terminals (52) is provided to couple the HART communication circuitry (82) to the two-wire process control loop (18) in a first configuration, and a second pair of electrical terminals (54) is provided to couple the Fieldbus communication circuitry (86) to the two-wire process control loop (18) in an alternative second configuration.
Abstract:
During manufacturing a unique encrypted authentication code is created for each product based upon device specific information relating to that product. The unique encrypted authentication code together with the device specific information is stored in a database, and a representation of the unique encrypted authentication code is stored on the product. To determine whether a product in question is authentic, the readable representation of the unique encrypted authentication code is read and sent to a server along with a request for product authentication. The server provides an indication of authenticity of the product in question based upon the unique encrypted authentication code received and the device specific information associated with that unique encrypted authentication code in the database.
Abstract:
During manufacturing a unique encrypted authentication code is created for each product 12 based upon device specific information relating to that product 12. The unique encrypted authentication code together with the device specific information is stored in a database 23, and a representation 14 of the unique encrypted authentication code is stored on the product. To determine whether a product in question is authentic, the readable representation 14 of the unique encrypted authentication code is read and sent to a server 22 along with a request for product authentication. The server 22 provides an indication of authenticity of the product 14 in question based upon the unique encrypted authentication code received and the device specific information associated with that unique encrypted authentication code in the database 23.
Abstract:
A corrosion rate measurement system (100) includes a sacrificial probe (106) configured to be exposed to a corrosive material. A sensor (110) is arranged to detect physical changes in the sacrificial probe due to corrosion of the sacrificial probe (106) from the corrosive material. Measurement circuitry (120) is connected to the sensor (110) and provides an output indicative of a corrosion rate of the sacrificial probe (106) from exposure to the corrosive material. The sacrificial probe has a physical characteristic which causes the sacrificial probe to corrode at a non-linear rate.
Abstract:
A coplanar process fluid pressure sensor module (192; 292) is provided. The module includes a coplanar base (194; 294) and a housing body (196; 296). The coplanar base (194; 294) has a pair of process fluid pressure inlets, each having an isolator diaphragm (110). The housing body (196; 296) is coupled to the coplanar base at an interface between the coplanar base (194; 294) and the housing body (196; 296). A differential pressure sensor (140) is operably coupled to the pair of process fluid pressure inlets, and is disposed proximate the coplanar base (194; 294) within the housing body (196; 296).

Abstract:
A process variable transmitter (260) for sensing a process variable of process fluid in an industrial process includes a process gasket (200) having a surface configured to form a seal with a process vessel face. The process gasket (200) is exposed to the process fluid through an opening in the process vessel face. A process variable sensor (220) is carried by the process gasket (200) and configured to sense a process variable of the process fluid and provide a sensor output (222). Measurement circuitry (282) coupled to the process variable sensor (220) provides a process variable transmitter output related to the process variable output.
