Early inclinometers or clinometers were made up of two basic parts, one of which is a flat side, or base, on which it stands, and the second a hollow disk just half filled with some heavy liquid. The glass face of the disk is surrounded by a graduated scale that marks the angle at which the surface of the liquid stands, with reference to the flat base. The line 0, being parallel to the base, when the liquid stands on that line, the flat side is horizontal; the line 90, being perpendicular to the base, when the liquid stands on that line, the flat side is perpendicular or plumb. Intervening angles are marked, and, with the aid of conversion tables, the instrument indicates the rate of[..]

Pressure transducers Only the front face of a pressure transducer is exposed to the sound field. The diaphragm responds equally to all sound pressure fluctuations hitting the surface, doesn't matter form which direction the sound. Pressure transducers have no directional characteristic, and are Omni directional. Pressure gradient transducers These microphones have a figure-8 pickup pattern along the longitudinal axis. They respond to the momentary sound pressure difference between two points A and B, which are a slight distance apart in the sound field. Pick up Patterns Omni directional An Omni directional microphone, reveres to Omni because it hears from all direction. Provide the[..]

Garage door openers are a modern day convenience and luxury investment invented in 1926 by C.G. Johnson. Since that time, door openers, as well as garage doors, have undergone many refinements. Originally, garage doors were composed of solid wood and were exceptionally heavy and cumbersome to open or close. It was not until much later that steel doors and fiberglass doors became commonplace. A variety of openers have different horsepower ratings in order to handle the variety of doors on the market today. Gone are the days of the 1940s and 1950s when a home owner would open their door with the remote, as well as the garage doors of multiple neighbors. Because of this and the use of[..]

High blood pressure, also known as hypertension, is measured in numbers based on the systolic and diastolic pressures of the blood. Systolic pressure measures the force in the arteries when the heart beats, while the diastolic pressure measures this force when the heart is at rest or relaxed. These measurements are shown in sequence from top to bottom - the systolic pressure measurement on top and the diastolic pressure measurement at the bottom. A small, portable instrument called a blood pressure cuff or sphygmomanometer is used to measure blood pressure. This consists of an air pump, a pressure gauge, and a rubber cuff and measures the blood pressure in units called millimeters of[..]

Asthma is a chronic respiratory disease that constricts and inflames the airways. This causes excess mucus to form in the lungs and a narrowing of the airways that causes the symptoms of wheezing, shortness or breath, coughing, and tightness in the chest. A severe constriction of the airways, often caused by allergens or excessive exercise, is called an asthma attack. One way that people with asthma can detect if they are going to have an asthma attack is by measuring their peak expiratory flow or peak flow for short. Peak flow measures how fast a person breathes out when that person tries his or her hardest. Basically, it tells a person how well his or her lungs and airways are working.[..]

“When a flow meter, level gauge or other device needs to be replaced, it needs to be done quickly,” says Ernst President, James Wolfe.  “Since our items last many years, replacement records are sometimes hard to come by.  We’ve done our best to simplify replacement,” he adds. According to Wolfe, visitors can either select by flow control type (sight glass, sight flow indicators, flow meters and totalizers, liquid level gauges and valves, glass and gaskets, sight window, switches flow and level, ejectors and eductors) or, if they have a model number, they can go to a model number index.  With one click they can get a complete listing of the type of flow control device they[..]

Fertigation, as the name implies, is the applying of fertilizers through irrigation water: Fertilization + Irrigation. This relatively new technique is being more and more commonly used in recent years, but the term "fertigation" is still not well recognized and many have not heard it. Fertigation has many advantages over other fertilization methods, and when properly used, it saves time and labor, fertilizers application is more accurate and uniform, and nutrient uptake by roots is improved. Two methods of fertigation: quantitative and proportional When using fertigation, fertilizfers solutions are prepared in advance in stock tanks and the solution is then injected into the irrigation[..]

Vibration analysis is becoming more and more well-known as a prognostic maintenance procedure as well as a support for machinery maintenance judgment and decisions. Generally, machines don't fail, malfunction, or break down without showing some symptoms or warning, which is often shown by an amplified level of vibration. To find out the nature and harshness of the machine flaw, and to therefore predict the failure of the machine or equipment, vibration measurement and analysis should be conducted. A machine has an overall vibration signal that comes from the several components and structures infused into it. Mechanical problems, however, create distinctive vibrations at varying[..]

rly every industry relies on the accuracy of scales for some portion of their work. Part of utilizing scales in the workplace involves the accurate record keeping of the weights of the objects that are weighed. When accuracy and precision are required of the scale, it is counterproductive to lose that precision because of human error during the record keeping process. Thankfully, there is no need to risk such a loss in productivity. A floor scale with a printer can relieve many frustrations regarding accurate record keeping. Most floor scales with printers work in a similar fashion to the traditional floor scale. These scales allow cargo to be loaded onto the sturdy platform that ideally[..]

In an earlier article in this e-zine I wrote about "Why use a regulator?". In this installment, the question posed is what do you do when you can't get at your pressure regulator due to it's location? You can control a remote compressed air regulator electrically or you can control the remote regulator with an air signal, therefore, wherever the regulator is on the machine or in the building, it can be controlled from afar by an operator or a programmable logic device. With an air piloted regulator a small "pilot" air regulator is installed in an accessible location. It's output signal is plumbed to the air-in signal port usually on the top of the remote 'main' air regulator. As the[..]
