摘要： A combustible gas detector or sensors having a multi-level sensitivity circuitry. The gas detector has a bridge circuit for outputting voltages indicative of gas concentrations contacting the bridge circuit. There is a power supply node electrically coupled to one end of the bridge circuit. There is also a voltage control circuit, coupled between the bridge circuit and the power supply node for controlling when at least a low and high input voltage level is supplied to the bridge circuit so that the bridge circuit has at least two levels of gas concentration discernability. The bridge circuit outputs distinguishable voltage levels for high gas concentrations in response to receiving the low voltage level. Additionally, the bridge circuit outputs distinguishable voltage levels for low gas concentrations in response to receiving the high voltage level.

摘要： A gas sensor for being placed into a gas stream. The sensor includes 1) a base having an axis that is perpendicular to the gas stream, 2) a sensor element on the base, 3) a catalysed sensor element on the base proximate the sensor element, for creating an exothermic reaction upon contacting the gas stream thereby forming a heated gas stream portion, and 4) the catalysed sensor element and the sensor element are positioned on the base so that as the base rotates about the axis, the heated gas stream portion will not contact the sensor element. In particular, the base has a second axis being perpendicular to the axis and separating the sensor element from the catalysed sensor element. Additionally, the invention provides a device that may have both the sensor element and the catalysed sensor element including a longitudinal axis. Wherein, both the sensor element and the catalysed sensor element may have many different shapes. Both the sensor element and the catalysed sensor element may have two or three sides that are coextensive with at least one void. As a result of having a void the base may include a bridge that connects at least one side of the sensor element and the catalysed sensor element to the base.

摘要： In accordance with the present invention, a non-contacting position sensor using bipolar tapered magnets is provided. A non-contacting position sensor in accordance with the preferred embodiment uses a pole piece having a first plate and a second plate. Four magnets are affixed to the first plate and second plate. Each magnet has a thick end and a thin end. Two magnets generate a linearly varying magnetic field having a first polarity, while the other two magnets generate a linearly varying magnetic filed having a second polarity. An air gap is formed in the space between the four magnets. A magnetic flux sensor is positioned within the air gap. The component whose position is to be monitored is rigidly attached to either the pole piece or the magnetic flux sensor, causing the magnetic flax sensor to move relative to the magnets within the air gap as the component moves. A varying magnetic field is detected by the magnetic flux sensor, resulting in a signal from the magnetic flux sensor that varies according to its position relative to the four magnets. The signal from the magnetic flux sensor is used to provide an indication of the position of the component to be monitored.
