How Great Teams are Created: When Sixteen Personalities Become One

Many of you have interviewed for a job and have found that you need to do a “psych profile” to determine if you can be further considered for the job opportunity. This can be an unnerving experience for many, especially if you are not aware of the real purpose in performing this exercise. What are companies really looking for when performing this evaluation?

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”
