Complex motion control problems arise from fluid or gas power applications because no matter the medium, it doesn’t respond to control inputs in a linear way. The decision to use closed loop or open loop control depends on the feedback and how the motion system utilizes it. Closed vs. open loop control valves might perform […]
Pressure-control valves are found in practically every pneumatic and hydraulic system. They help in a variety of functions, from keeping system pressures below a desired limit to maintaining a set pressure level in part of a circuit. Different types of pressure control valves include relief, reducing, sequence, counterbalance, safety, and unloading. All of them are […]
A mass flow meter, or inertial flow meter, measures the mass flow rate of gases or liquids traveling through a tube. The gas passes by a fixed point within the meter and it measures the mass per unit time, not the volume per unit time. There are many different types of mass flow meters that […]
Anesthesia is a term that we are all familiar with. It is a general term that is applied to painkillers and being put under for surgery. It is quite a medical breakthrough that helps not only patients but also doctors. Anesthesia means an insensitivity to pain, especially artificially induced by the administration of gases or […]
In the medical device industry, there is an increasing demand for sleeker, smaller designs and speed to the marketplace with the latest and greatest products. Engineers tasked with designing and creating respiratory equipment such as ventilators and anesthesia machines have a host of critical challenges in front of them. End-users demand top performance and compliance […]
