Swift weighing transmitter – high-speed weighing module for industrial applications

The Swift weighing transmitter is a powerful weighing module and high-speed transmitter for static and dynamic weighing systems. With a measuring rate of up to 2,400 measurements per second, this weighing electronics unit is suitable for both classic industrial weighing tasks and high-speed processes in mechanical engineering, dosing systems, and automated production plants.

With versions for DIN rail mounting or panel mounting, the weighing transmitter can be flexibly integrated into existing systems and control cabinets. Various interfaces, digital inputs and outputs, as well as optional communication standards enable easy connection to PLC controllers, PC systems, and remote-controlled equipment.

The Swift can be used for both static weighing systems and dynamic weighing applications.

Precise weighing electronics with high measuring speed

The integrated 24-bit AD converter offers a high internal resolution of up to 16,000,000 divisions and enables up to 500,000 external divisions. Due to the high measuring speed, the weighing module is also suitable for applications where weight values must be recorded and transmitted particularly quickly.

The configuration and calibration can be carried out directly via the keypad or via a computer interface. In addition to calibration with certified test weights, numerical calibration in mV is also possible. This allows for commissioning, for example, by entering the nominal range and the nominal characteristic value of the load cell.

Interfaces and PLC connection

For communication with higher-level controllers and systems, RS-232 and RS-485 with Modbus RTU and ASCII are available. Profibus or Profinet are also available as options.

A galvanically isolated and configurable analog output supports signal transmission with -5 V, 0–10 V, 0–20 mA, or 4–20 mA. This allows the weighing transmitter to be integrated directly into automated control and regulation processes, for example.

Additional control functions can be implemented via the optically isolated digital inputs and digital relay outputs. Multiple weighing modules can also be connected to each other via the same data bus.
