• Parameterizable for highly versatile applications
• Flexible adaptation to different requirements with SIMATIC
• Simple adjustment of scale using the SIWATOOL FTC program
• Theoretical adjustment without calibration weights
• Replacement of module without renewed adjustment of scale
• Recording of weighing sequence
• 8 totalization memories with different digit intervals
• Can be used in Ex applications

The SIWAREX FTC weighing module is the optimum solution wherever users place high demands on continuous weighing procedures. Thanks to its outstanding measuring properties, it can measure weights with extreme accuracy in up to three ranges. When it comes to force measurements, it can measure the value bidirectionally.

Typical applications for SIWAREX FTC include:

• Flowrate/flow measurement
• Belt volume measurement
• Material loading, summation
• Flowrate/flow control
• Belt load measurement
• Belt scale / weighfeeder
• Loss-in-weight scale
• Force measurement

Function

The main tasks of SIWAREX FTC are the high-precision measurement of the current weight, and the exact calculation of the conveyed quantity or flow. In "Force measurement" operation mode, SIWAREX FTC measures the force in both directions.

The conveyed quantity can be recorded in 8 totalization memories. Through integration in SIMATIC it is also possible to directly control scale operation by means of a PLC program. This means that the tasks can be sensibly divided: The weighing functions are implemented in the SIWAREX FTC and the interlocking and logic functions for the plant control in the SIMATIC CPU.

Weighing functions

The following operating modes can be set:

Weight measurement and force measurement

In this operating mode, the system determines the weight value or the force, processes it in the PLC, and then displays it. For this purpose, you can select the configuration package.

Belt scale / weighfeeder

This operating mode implements the functions of a belt scale. It calculates the typical process values: belt load, flowrate, and belt speed. You can use commands to control the belt and display the required values. Activating the SIMATIC PID controller can implement a weighfeeder.
