The Role Of The Load Cell Amplifier

For most types of automated control systems on lines or for equipment where tension has to be maintained, load cells are used as the way to provide the precision measurement required. The load cell operates by sensing a change in tension or force and then converting that movement into an electrical signal. The use of a load cell amplifier comes after the load cell completes the measurement. This is a component that reads the signal and completes what is known as signal conditioning to provide the necessary output that can be utilized by automatic systems that control brakes and drives on a system. The most common reason for the use of a load cell amplifier is the often weak signal that is produced by the load cell itself. Without the ability to amplify the signal, the slight variations in force would be recognized by the load cell, but would not generate a strong enough signal to be detected by the automated equipment sensors. What to Consider It is important to realize that the amplifier for the load cell doesn’t actually read the force or change the information coming from the load cell. It simply enhances or amplifies the data in a way that is uniform and consistent. There are different types of amplifiers designed to work with various load cells. The two basic options are the digital or analog models. They do need to be selected to match the type of load cell. Some load cell amplifier models work on a single channel while others are more flexible and can be used in a wider range of applications. Many manufacturers of load tensioning systems recommend the use of their amplifiers in a tension control system while others are universal in their application and...

Problems with Powdered Borax Applications

Borax has many commercial uses today. For example, it is an important additive for starch adhesives and sees use in many cleaning and detergent products. Other industries also use borax (like cosmetic, chemical, and pest control companies). It’s sometimes used to extract gold from minerals (instead of mercury). However, in most cases, liquid boric acid is better than powder and here are some reasons why. What is Borax? Also called sodium borate (from boron), Borax is a white powder made from soft crystals. It dissolves in water easily. By combining borax with a mineral acid like hydrochloric acid, you can make liquid boric acid, and it has many of the same properties as powdered borax. Powdered Borax and Health Issues Borax makes an effective insecticide, and you’ll see it in preparations to kill roaches and fleas. However, even though it has some toxicity, it’s not considered lethal to humans unless one ingested a very large amount. Borax can create a lot of dust, especially when used in commercial or industrial applications. This dust is an irritant when inhaled. Inhaled borax dust irritates the respiratory tract. This can cause problems in people with allergies and can cause coughing and sneezing. Some people may develop skin irritation when exposed to borax dust. Prolonged exposure can cause other problems like headaches and sinus problems. Borax carries health concerns for women of childbearing age. Exposure could have an effect on fertility and may cause damages to unborn children. Solving the Problems Associated with Borax One of the easiest ways to lower the health hazards associated with powdered borax is to turn it into liquid boric acid. In fact, it’s beneficial to the corrugated products industry because boric acid helps to improve the effectiveness and consistency of starch glues. This saves a lot of time and...

Tips For Choosing Acme Screw Options

The production of Acme and lead screws is a complex procedure that requires several steps that must be done with complete precision. The specific thread pattern of the Acme screw allows for easy movement of the Acme nut along the thread pattern without any catching or wedging as the nut moves along the length of the thread. The Difference While the Acme screw falls under the general category of the trapezoidal thread form, it is different. The typical trapezoidal thread form has a 30-degree thread angle while the Acme thread is set at 29 degrees. This is measured at the top of each thread and between the next thread up or down the shaft. It is important to realize this 29-degree thread remains the same regardless of the diameter. In addition, the thread height is half of that of the pitch and the top and bottom or the crest and valley of the thread are flat, not rounded or pointed in shape. This specific thread shape is important, as it allows the thread to carry additional weight over other shapes. Both standard and split nuts can be used on this type of thread form. The split nut will open along the length to allow the nut to be placed on the bolt. It also provides the option to move the nut into position up or down the length of the thread without having to turn it into place. Considerations When choosing Acme screws options, it is important to choose a manufacturer offering precision machining and production options, particularly when the order calls for customized components. It is important to know the class of Acme screws you required as well as the diameter and length. Additionally, these screws can be configured with either a right or left-hand thread as well as single or multiple thread...

Tips For Finding The Correct Tension Indicator For The Job

In all types of operations from paper manufacturing to films, steel or winding operations, there is the need to have the process carefully controlled. When precision in the tension on the material is critical, it will be essential to have a tension indicator that is accurate, dependable and rugged enough to stand up to demanding work environments. These devices are carefully designed to suit the specific equipment. The size, dimensions, and capacities of the different indicators will be important to compare, but it often the dependability and durability factors that are most considered factors after accuracy. In specialized processing where heat, humidity, and vibration are a concern, the durability factor is often the primary consideration. Analog or Digital There are two different types of tension indicator models. One is the analog model, which will provide a metered type readout on the indicator. This doesn’t mean a simple system and top models will offer features and functions such as tare adjustments, filtering, balancing and summing circuitry, tension monitoring options and controls, full meter scale adjustments and a stainless steel enclosure. Digital tension indicator units feature the same type of construction and features, but they utilize a digital readout that provides specific tension rather than the gauge type readout. With top manufacturers the indicator decimal point specification will be pre-set, allowing for the precision display required. Tension Range Measured Different applications will require a different range of tensions. For example, in the processing of plastic films, extremely precision tension control is required. Even slight variations can result in wrinkles or stretch of the plastic that can render the roll useless in specific types of packaging. These tension controls and indicator system need to be able to adjust to meet the requirements of the different plastics. Look for systems that offer adjustable tension load ranges that work for your current processing needs and those of the...
