The Role Of Koganei Pneumatic Valves And Crouzet Optical Sensors

Optical sensors work on a relatively basic principle. Each sensor consists of two main parts – a light emitter and a light receiver. Depending on the particular type of sensor, the sensor could be designed to sense either the absence or presence of light. For example, a sensor might be installed so that the light emitter on one side constantly emits light that is received by the receiver on the other side. When an object passes between the emitter and receiver, the light is disrupted and this tells the machine that an object is there. This allows machines to function with a minimum of human interference and guidance, making automated processes more effective.

Another part of the body that is especially vulnerable are the hands. While your hands are not an especially fragile part of your body, they are the part that you use to operate machinery and accomplish various tasks, bringing them close to heavy equipment and thus placing them in harm's way. Gloves help to prevent injury if you were to accidentally touch a hot piece of equipment or come into contact with a corrosive substance.

Leaks are a much more serious problem, because they can indicate fissures in the structural integrity of your system. While most leaks are actually relatively harmless, and are simply seals that have not been properly installed or faulty valves, sometimes metal pipes and other supposedly solid parts can crack under the high pressure of a pneumatic system. When such cracks appear, air can begin to leak, but this is merely a precursor to a more catastrophic failure. It is not unknown for such cracks to result in metal pipes exploding or equipment shattering as the cracks widened and eventually split open. Spotting and identifying leaks of this sort requires close attention to the air pressure gauges and also regular detailed physical inspections of your system.

There are many modern applications of pneumatic technology that are not even apparent unless you were to conduct a careful study of certain technologies. The engines on a jet plane, for example, make use of pneumatic technology to operate. Another example is the set of tools that you find in every dentist's office, including the drill that is the instrument that causes great fear in many people still and which runs on pneumatic power. Pneumatic technology remains relatively unknown because most people have been brought up only being taught that machinery runs on fuel-driven motors or electricity. Thus even when a dentist's drill gives off a telltale hiss of exhaust air, people do not make the deduction that it must be powered by air and is hence a pneumatic tool.

Directional Valves- these valves are placed just prior to the actuators and their main function is to stop, release or re-direct the compressed air to the actuators at the desired time interval.
