摘要： A humidity sensing apparatus and method includes a humidity sensor capable of measuring relative humidity and a heater located about and proximate to the humidity sensor wherein a portion of the heater comprises a material that permits a diffusion of air through the material of the heater. A sensing area is generally formed between the heater and the humidity sensor, wherein the heater provides a heated environment within the sensing area in order to evaporate water droplets that form within the sensing area and reduce relative humidity to a measurable level and measure supersaturated air within the sensing area.

摘要： Sensor systems and methods are disclosed herein. A relative humidity sensor can be associated with one or more heating elements, wherein a perimeter of the relative humidity sensor is surrounded with a relatively conductive material. A thin substrate material can surround and laminate the heating element, such that the heating element is porous to permit humid air to pass through the heating element and wherein the at the heating element is assembled slightly offset from a surface of the relative humidity sensor. Air that is saturated with water vapor can then pass through and be heated by the heating element in order to evaporate water droplets associated with the water vapor to thereby reduce relative humidity to a measurable level.

摘要： A modular sensor assembly in which a sensing module may be packaged and provided separately from a signal processing module and which, in some applications, may facilitate disposal and/or replacement of the sensing module when exposed to a “dirty” or “contaminated” environment without requiring disposal and/or replacement of the entire sensor assembly. In certain applications, the sensing module may include at least one transducer or sensor and a local memory containing a set of conditioning coefficients. The sensing module may be removably coupled to a signal processing module which, in some cases, may be configured to download the set of conditioning coefficients stored in the local memory of the sensing module, and to use the set of conditioning coefficients to produce a substantially linearized output signal.

摘要： A fluid flow sensing device can include a tapered fluid flow channel formed into a main channel defining a fluid flow tube as an alternate fluid flow path. A tapered fluid flow channel can bypass some fluid flow from the main fluid flow channel into the alternate fluid flow path and a flow sensor disposed within the alternate fluid flow path. The tapered flow channel is tapered in a direction of fluid flow toward the flow sensor to thereby reduce flow eddies and enable optimal sensing performance by fluid flow sensor. An upstream fluid flow channel and a downstream fluid flow channel can be molded into the main fluid flow channel, especially bypassed in the fluid flow path of the main fluid flow channel. A fluid flow sensor can be placed between the upstream fluid flow channel and the downstream fluid flow channel for measuring fluid flow rate the channel.

摘要： The present disclosure relates generally to flow sensors, and more particularly, to devices and methods for providing a pressure drop through a flow sensor at a given flow rate. In one illustrative embodiment, a sensor assembly includes a housing with a first flow port and a second flow port. The housing may define a fluid channel extending between the first flow port and the second flow port, with a sensor positioned in the housing and exposed to the fluid channel. The illustrative sensor may be configured to sense a measure related to the flow rate of a fluid flowing through the fluid channel. A flow restrictor may be situated in and integrally molded with at least one of the first flow port and the second flow port. The flow restrictor may be configured to accurately provide a pressure drop through the flow sensor at a given flow rate.

摘要： A fluid velocity sensor includes a sensor die for detecting a fluid property of a fluid flowing through a low resistance flow channel defined by a flow channel wall. One or more tap can be oriented facing into a direction of a flow stream of a fluid flowing through a flow channel defined by a channel wall, wherein the tap(s) leads to the low resistance flow channel, which directs the flow to the sensor die. At least one or more other taps can be located to face perpendicular to the direction of flow, such that the fluid after passing over the sensor die continues on a low resistance path to the other tap(s) facing perpendicular to the direction of flow in order to determine a velocity pressure based on a difference between pressures. The fluid velocity sensor can be arranged in a uni-directional or bidirectional fluid flow configuration.

摘要： Sensor systems and methods are disclosed herein. A relative humidity sensor can be associated with one or more ceramic heating elements configured from a porous material. In general, a perimeter of the relative humidity sensor is surrounded with a relatively conductive material. A resistive material surrounds one or more of the ceramic heating elements, such that air that is saturated with water vapor passes through the porous material of the ceramic heating element(s). Water vapor can therefore be heated by the ceramic heating element(s) in order to evaporate water droplets associated with the water vapor and thereby reduce relative humidity to a measurable level. The porous material of the ceramic heating element(s) can be provided via a plurality of laser drilled holes to create such porosity.
