What is Hysteresis?

Hysteresis Defined

According to Merriam-Webster, hysteresis isthe “lagging of a physical effect on a body behind its cause (as behind changed forces and conditions)”. When outside forces act on an object, that object will either immediately spring back to its original state, or more likely, it will somehow change or exhibit properties from previous deformations.

What is a Hydrogen Fuel Cell?

Although hydrogen is in its infancy as a fuel source, its future is incredibly bright. The technology behind hydrogen fuel cells is improving daily and its viability as a replacement to the internal combustion engine seems likely. Hydrogen is already being used in specialty vehicles such as forklifts and buses, and it’s only a matter of time before infrastructure is in place to serve the consumer automotive market. Why do hydrogen fuel cells have such great appeal? Because their only byproducts are heat and water vapor, making hydrogen fuel cells a truly zero-emission locomotive technology.

注油传感器与非注油传感器相比有哪些缺点?

In the pressure sensing industry there are many different sensor technologies, but all sensors can be broken down into two classifications; oil-filled, non-oil filled. An oil-filled sensor refers to a sensor that uses oil as a transfer medium between a diaphragm and the sensing element. Oil-filled sensors appeal to many manufacturing applications due to itsmaterial compatibility,low cost, and ease of implementation. Although these sensors are becoming a standard, there are several drawbacks to selecting an oil-filled sensor over a non-oil filled sensor.
