摘要： Flow sensor assemblies having increased flow range capabilities are disclosed. In one illustrative embodiment, a flow sensor assembly includes a housing with an inlet flow port, an outlet flow port, a fluid channel extending between the inlet flow port and the outlet flow port, and a bypass channel having a pair of taps fluidly connected to the fluid channel at separate locations. A flow sensor for sensing a measure related to a flow rate of a fluid flowing through the fluid channel can positioned in the bypass channel. A pressure differential between the two taps of the bypass channel can drive a fraction of a fluid flowing through the fluid channel through the bypass channel. The flow sensor assembly may be configured to achieve, control, and/or balance a desired fraction of fluid flow through the bypass channel and past the flow sensor.

摘要： A flow sensor apparatus and method. A seal with a conductive interconnect is provided that includes a mass flow sense element mounted to a housing containing a thick film and/or thin film bridge structure for sensing media (e.g., mass flow) within a flow tube. The seal effectively isolates wirebond pads and electrical connections from the sensed media. The media, whether liquid or gas, can contain ionics that eventually contaminate the top of the mass flow sense element. The use of the seal with the conductive interconnect thus seals off the electrical connections and prevents exposure to the sensed media.

摘要： Flow sensor assemblies having increased flow range capabilities are disclosed. In one illustrative embodiment, a flow sensor assembly includes a housing with an inlet flow port, an outlet flow port, and a fluid channel extending between the inlet flow port and the outlet flow port. One or more partitions are provided in the fluid channel of the housing to define two or more fluid sub-passages. A flow sensor, for sensing a measure related to a flow rate of a fluid flowing through the fluid channel, is positioned in one of the two or more fluid sub-passages. In some cases, the cross-sectional area of each of the two or more fluid sub-passages may be substantially the same, but this is not required. The housing may be formed from a single molded part defining the inlet and outlet flow ports, at least a portion of the fluid channel, and one or more of the partitions. In this case, a top cover may be provided and mounted to the housing to define the remaining portion of the fluid channel, if desired.

摘要： Methods and devices for increasing a sensor resolution are disclosed. In one example, a two measurement process is used. A first measurement is used to effectively measure across a full range (e.g. 0 to 5 VDC) of the sensor. This first measurement may identify the current operating point of the sensor (e.g. 3.5 VDC). A second measurement may then be made to effectively measure across a sub-range of the sensor that encompasses the current operating point of the sensor (e.g. across a sub-range of 3.0 to 4.0 VDC for a current operating point of 3.5 VDC). The gain of the amplifier may be raised during the second measurement to produce a higher resolution measurement. In some cases, the first measurement may be used to determine an appropriate offset that may be applied so as to scale the amplifier to the desired sub-range of sensor that includes the current operating point of the sensor. In some cases, the two measurements may be used together to compute an effectively higher resolution measurement signal. In some cases, this may allow for a smaller and/or cheaper sensor to be used, while still achieving good results.
摘要翻译：公开了用于增加传感器分辨率的方法和装置。在一个示例中，使用两个测量过程。第一测量用于有效地测量传感器的全范围（例如0至5VDC）。该第一测量可以识别传感器的当前工作点（例如3.5VDC）。然后可以进行第二测量以有效地测量包含传感器的当前工作点的传感器的子范围（例如，对于3.5VDC的当前操作点，在3.0至4.0VDC的子范围内）。放大器的增益可能在第二次测量期间提高，以产生更高分辨率的测量。在一些情况下，可以使用第一测量来确定可以应用的适当的偏移，以便将放大器缩放到包括传感器的当前工作点的传感器的期望子范围。在一些情况下，可以一起使用两个测量来计算有效地更高分辨率的测量信号。在某些情况下，这可能允许使用更小和/或更便宜的传感器，同时仍然获得良好的结果。

摘要： A flow-through pressure sensor apparatus that reduces the dead space of a flow tube utilized to provide fluid communication between a pressure sense die and a fluid and with an absolute minimum trapped volume. A cover (e.g., plastic) with two-molded ports can be added to one side of the pressure sense die utilizing molded-in solder pins to improve ruggedness and rigidity. A temperature and a humidity sensor can also be mounted to a substrate (e.g., ceramic) in the flow path and can be connected to a programmable compensation integrated circuit on the opposite side utilizing a clip end of mounting pins or by vias through the substrate outside a pressurized area.
