If you operate a moving and continuous processing line, you must have accurate tension. Failure to achieve this results in inconsistent quality. This is something no industry intent on being successful can permit. Tension controllers are the answer. However, controllers do not operate in a vacuum. They require the implementation of other integrated devices including a load cell transducer.
What Is a Load Cell?
A load cell is a transducer or sensor. It takes the load or other force acting upon it and converts it into an electronic signal. This signal may take the shape of the following:
* Voltage change
* Current change
* Frequency change
The type relies on the type of load cell employed and the specific circuitry in use.
Load cell transducers come in different types. These include resistive and capacitive. Your choice will depend on a number of factors.
Factors in Selecting Load Cells
When you are considering selecting the appropriate load cell transducer for your application, be sure you look carefully at the following factors concerning the application and the load cell
* Capacity
* Size of the load cell
* Conditions of the operating environment e.g. indoor, outdoors, controlled or uncontrolled temperatures
* Measurement duration required
* Speed measurement
* Level of accuracy demanded
* Loading direction – tension and/or compression
* Mounting options
* Required output – Analog or Digital
* Certifications or testing i.e. ASTM E-74, NTEP, OIML, R & D
* Total operational costs
These comprise the basic considerations before selecting the right load cell.
Load Cell Transducer
Choosing the correct load cell involves understanding the operational factors of your machinery. It also requires awareness of all factors that may affect the production incomes. By carefully considering all aspects of equipment – including operators and environmental issues, it is possible to find a load cell transducer that will address your concerns, maintain the right level of accuracy and increase productivity.
