IFM Efector Inc. has released a new line of pump diagnostic pressure sensors. The new PIM series performs the tasks of pump monitoring and pressure detection and alerts users of fluctuations in the system, including cavitation, trapped air, blockages and deposits.
When first installed, the pump sensor performs a teach function, where it measures the high-frequency pulsation signature and flow data of the healthy pump and stores it as a reference. Then, in instances where there are deviations from the average pulsation signature such as in instances of cavitation, the sensor acknowledges the variations and triggers an alarm.
The sensor’s display alternates between numeric system pressure and the operating state of the pump. It also includes a numeric push-button display for entering data. The list price for the PIM series is $573.
What makes this movie stand out from the typical high school sports story is that the teenagers are undocumented immigrants, and the big game is a NASA-sponsored marine robotics competition. Like many other Hollywood movies, however, Spare Parts only tells part of the story. What the film shows -- and doesn’t show -- raises important issues affecting STEM education in the US.
Instead of sifting through huge amounts of technical data looking for answers to assembly problems, engineers can now benefit from 3M's new initiative -- 3M Assembly Solutions. The company has organized its wealth of adhesive and tape solutions into six typical application areas, making it easier to find the best products to solve their real-world assembly and bonding problems.
Load dump occurs when a discharged battery is disconnected while the alternator is generating current and other loads remain on the alternator circuit. If left alone, the electrical spikes and transients will be transmitted along the power line, leading to malfunctions in individual electronics/sensors or permanent damage to the vehicle’s electronic system. Bottom line: An uncontrolled load dump threatens the overall safety and reliability of the vehicle.
