In many applications, the use of an additional component is ideal to provide very precision measurements across even slight changes in resistance on a load cell. A load cell amplifier can provide this enhanced ability to both measure as well as monitoring very precise web tensions.
These are typically very streamlined components that are highly compatible with most load cells and with most equipment and operations. It is important to ensure the amplifier has excellent EMI (Electromagnetic Interference) shielding to avoid complications in operation from other electronics within the equipment or in the facility.
Considerations
The component is not always necessary in all applications. However, the addition of the load cell amplifier in the tension control system can be instrumental in working with some films and other materials to fine tune the tension and provide consistent, quality film to the equipment.
In choosing the best model and design in an amplifier, there are a few basics to keep in mind. These are particularly important if you are choosing an amplifier that is not from the same manufacturer as the load cell. However, they are also important to verify even when purchasing from the same company.
Ease of Installation
The majority of amplifiers for load cells are designed to be very easy to install. They should come with wiring diagrams and designed for easy application and installation. Most companies that produce load cells and amplifiers will also have an output on the load cells, which is ideal for a simple and very quick installation.
It is also possible to choose the load cell amplifier as an option at the time of purchase of the load cell. If there is some confusion as to the need for the amplifier, talk to the load cell manufacturer and discuss your options.
