The weighing and proportioning system is of significant importance in many industrial processes , where many different weighing tasks have to be handled . Both programmable controllers (PLC) and process control systems (PCS) are used to automate production processes.
There are many different types of scales which work together with automation systems depending on the requirements .
Production automation places the following demands on the weighing technology :
- Flexibility with respect to typical scale functions .
- Adaptability to the automation task .
- Integrated communication concept .
Scales which can satisfy these demands can be classified as part of the automation system .In this sense , the scale is an intelligent automation object comprising :
- Sensor technology
- Controller
- Actuator technology
And carries out its tasks according to the definitions the control system .
The distribution of weighing functions within the automation system has been constantly changed within the last few years . The reasons for this can be found in the search for an efficient solution to weighing tasks in the automation environment . The performance of the hardware components is no longer the only reason for applying a certain solution architecture . The demands placed on a modern weighing solution include the scale - based requirements :
- High operational reliability
- Simple operation
- Very good reproducibility
- High accuracy
As well as the requirements associated with the automation properties :
- Uniformity (Hardware & Software )
- Flexibility
- Standardization
And ...
