Thermal Dispersion Flow Switches

Thermal Dispersion Flow Switch Series TDFS

Dwyer Instruments offers several flow measuring products that use a thermal sensing element.

Thermal dispersion flow sensors use a temperature element that is heated up beyond the media temperature. Based on calorimetry, the flow moving past the sensor will have a cooling effect that is directly proportional to the flow velocity. The heat is convected from the heated probe surface to the boundary layer of the fluid flowing over the heated surface.  Continue reading “Thermal Dispersion Flow Switches”

Pressure Sensor Accuracy

Pressure Sensors

Why is pressure sensor accuracy important? From a manufacturer’s point of view, the wrong sensor can cause expensive quality or efficiency problems. This is why it’s important to understand how manufacturers calculate accuracy and recognize what parameters to look at when comparing pressure sensors.

By understanding how manufacturers calculate accuracy, you will be able to make a more informed decision when evaluating pressure sensors. This ensures that the next sensor that you select will have the required accuracy at the right price for the application. Continue reading “Pressure Sensor Accuracy”

How the Sensor Market is Championing the Internet of Things (IoT)

The Internet of Things (IoT) is the concept of creating a large network of devices that all interact with each other to ultimately change the way we live and work. By connecting our phones, cars, and other devices to this network and linking them together with shared data/services, we have the potential to revolutionize the way we do everyday tasks. This innovation is at the root of ideas like autonomous vehicles and smart cities that improve efficiency and simplify complicated systems. From an industrial standpoint, the IoT can be applied anywhere from the factory to agricultural fields and offers the opportunity to place all the steps in a process onto an automated course held together by the overarching Internet.
