| 摘要 | A passively powered gas sensor for remotely reading and transmitting a gas pressure of a system, comprising a hollow cylindrical body, a stem axially aligned and extending outwardly from a first surface of the hollow cylindrical body, a pressure sensing element in the stem, and an antenna coupled to the pressure sensing element, where the antenna is located within the hollow cylindrical body and the stem. The pressure sensing device is polled remotely by a polling device, and powered by the polling device. | ||

| 主权项 | 1. A passively powered gas sensor for remotely reading and transmitting a gas pressure of a system, comprising: a hollow cylindrical body; a stem axially aligned and extending outwardly from a first surface of the hollow cylindrical body, the stem having an interior surface and a threaded exterior surface, the stem including a path that permits a gas to enter only partially into the stem; a pressure sensing element in the stem adjacent the path that permits a gas to enter only partially into the stem; an antenna coupled to the pressure sensing element, where the antenna is located within the hollow cylindrical body and the stem; wherein the pressure sensing device is polled remotely by a polling device, and powered by the polling device; and wherein the passively powered gas sensor has no moving components and does not continuously monitor a pressure. | ||
