摘要： A wireless sensor network gateway includes safe side circuitry, hazardous side circuitry and isolation circuitry, which are supported by a housing. The safe side circuitry includes a safe side power circuit, and a safe side data input/output (I/O) circuit. The hazardous side circuitry includes a hazardous side power circuit, and a hazardous side data I/O circuit. The isolation circuitry divides the safe side circuitry from the hazardous side circuitry. The isolation circuitry includes a power isolation circuit that couples the safe side power circuit to the hazardous side power circuit and forms an intrinsic safety barrier between the safe side power circuit and the hazardous side power circuit, and a data isolation circuit that couples the safe side data I/O circuit to the hazardous side data I/O circuit and forms an intrinsic safety barrier between the safe side data I/O circuit and the hazardous side data I/O circuit.

摘要： A wireless field device for use in monitoring acoustic noise includes an acoustic sensor configured to sense acoustic noise. Processing circuitry coupled to the acoustic sensor is configured to identify a hazardous noise condition based upon the sensed acoustic noise and a personnel noise exposure standard. Output circuitry provides a warning output in response to an identified noise condition. A system is also provided which uses one or more acoustic sensors implemented in wireless field mounted monitors.
