摘要： A clamping current and voltage sensor provides an isolated and convenient technique for measuring current passing through a conductor such as an AC branch circuit wire, as well as providing an indication of an electrostatic potential on the wire, which can be used to indicate the phase of the voltage on the wire, and optionally a magnitude of the voltage. The device includes a body formed from two handle portions that contain the current and voltage sensors within an aperture at the distal end, which may be a ferrite cylinder with a hall effect sensor disposed in a gap along the circumference to measure current, or alternatively a winding provided through the cylinder along its axis and a capacitive plate or wire disposed adjacent to, or within, the ferrite cylinder to provide the indication of the voltage. When the handles are compressed the aperture is opened to permit insertion of a wire for measurement.

摘要： Embodiments of the invention are directed to an integrated sensing system that includes a movable orientation device configured to dynamically position the movable orientation device based on receiving an air-flow. A gas sensor is coupled to the movable orientation device. The gas sensor includes a recognition element configured to detect a chemical in a plume. The movable orientation device is configured to perform a synchronized sensing operation that includes, based at least in part on the movable orientation device receiving the air-flow, moving the movable orientation device to dynamically maintain a predetermined orientation of the movable orientation device relative to a direction of the air-flow. The predetermined orientation includes positioning the gas sensor in a path of the air-flow, wherein the air-flow is influencing the plume to move along the path such that the recognition element is exposed to the plume.

摘要： A corrosion sensor includes a plurality of metal strips having different thicknesses. A first metal strip with the least thickness is first employed to provide sensitive corrosion detection. After an exposed portion of the first metal strip is consumed, a second metal strip having a second least thickness can be employed to provide continued sensitive corrosion detection employing a remaining un-corroded portion of the second metal strip. The plurality of metal strips can be sequentially employed as exposed portions of thinner metal strips become unusable through complete corrosion and un-corroded exposed portions of thicker metal strips become thin enough to provide sensitive corrosion detection.
