    摘要: A sensor module has an outer module housing with an fluid inlet and a feedthrough with five electrical contacts. A transducer circuit in the module has a sensor connected to the inlet, a regulator connected to contacts 1, 2 and a transceiver providing a serial output to contact 3. A logic circuit is selectable to a first mode of operation in which the logic circuit generates ON-OFF logic levels on contacts 4, 5 or it can be selected to a second mode of operation in which the logic circuit detects ON-OFF logic levels on the contacts 4, 5.

    摘要: A modular process transmitter having a scalable EMI/RFI filtering architecture includes a unitized sensor module and a transmitter module. The unitized sensor module is adapted to operate as a stand-alone process transmitter. The transmitter module can couple to the unitized sensor module to expand the capabilities of the unitized sensor module. The unitized sensor module includes a sensor housing, a sensor circuit and a removable sensor EMI/RFI filtering circuit. The sensor circuit provides a sensor output in accordance with either a local format or a first communication protocol. The sensor EMI/RFI filtering circuit filters noise in accordance with the first communication protocol. The transmitter module includes a transmitter module housing, a communications circuit, and a transmitter module EMI/RFI filtering circuit. The communications circuit is adapted to receive the sensor output from the sensor circuit in the local format and generate a scalable output in accordance with a second communication protocol. The transmitter module EMI/RFI filtering circuit is adapted to replace the sensor EMI/RFI filtering circuit and filter noise in accordance with the second communication protocol.

    摘要: Disclosed is a process control transmitter having an externally accessible DC circuit common that eliminates the need to perform level shifting of signals communicated between the transmitter and external processing electronics. The process control transmitter includes first, second and third terminals which feedthrough a housing. Circuitry contained in the housing is coupled to the first, second and third terminals and is adapted to communicate information to external processing electronics through the second and third terminals using a digital signal that is regulated relative to a DC common that is coupled to the second terminal. External processing electronics can couple to the second and third terminals and interpret the digital signal without having to perform level-shifting adjustments.

    摘要: An industrial process field device is provided. The device includes wireless process field device electronics disposed within the industrial process field device and at least one battery cell disposed within the industrial process field device and operably coupled to the wireless process field device electronics. A circuit is provided that senses an electrical characteristic related to the at least one cell and provides an output to a switch to decouple the at least one cell from the industrial process field device electronics in response to certain conditions. Such conditions include too much current flowing from the at least one cell; the voltage of the at least one cell being too low; or a short circuit being generated or otherwise observed.

    摘要: In a facsimile receiver, a copy medium is advanced between a platen of triangular cross-section and a plurality of stylii mounted on a moving belt. The platen is rotatable so as to allow different edges of the platen at the apices of the triangular cross-section to be placed in contact with the copy medium. In addition, the platen may be rotated to a position where a flat side of the platen is juxtaposed to the copy medium so as to allow the copy medium to be fed between the stylii and the platen during loading and unloading. The stylii are formed from sheet-like members with a broad surface in contact with the copy medium. Three such stylii are mounted on a sheet metal belt through which the stylii are electrically energized as the belt moves.
