Difference between photohelic and magnahelic guage?
Photohelic gauges measure pressure using a diaphragm mechanism that converts pressure into a measurable signal. Magnahelic gauges use a magnetic mechanism to measure pressure differentials across two points. Both gauges can display the pressure readings on a dial or digital display.
What does the word photohelic mean?
"Photohelic" typically refers to a type of pressure switch or gauge that combines both pressure measurement and control functions with the option for visual monitoring or recording through photography. It is commonly used in industrial applications to measure and control air pressure in ventilation systems.
What does Photohelic mean?
Photohelic is a trademarked name for a type of pressure switch and pressure gauge combination device manufactured by Dwyer Instruments. It combines the functions of measuring and controlling pressure in one unit, with the ability to set high and low pressure setpoints that trigger electrical switches for control purposes.
What is the net force on the force gauge?
If the force gauge isn't moving, the the net force must needs be zero.
What is the difference between gauge redundancy and symmetry?
Gauge redundancy arises in physical theories when certain configurations are physically equivalent. Symmetry, on the other hand, refers to invariance of a physical system under a transformation. In gauge theories, the gauge redundancy leads to local symmetries that leave physical observables unchanged.
