The ProRate PLUS-M feeder is designed for gravimetric feeding of free flowing bulk solids that do not require agitation. It is ideal for feeding pellets in the plastics industry. The single screw feeder with extension hopper is suspended on a single-point weighing system in a compact frame. Proven Smart Force Transducer (SFT) weighing technology provides accurate and reliable performance.

• ROBUST design
• RELIABLE feeding, weighing and control technology
• SIMPL E to install and operate
• Economical feeding solution

• State-of-the- art digital weighing technology for reliable performance
• ProClean Rail for easy cleaning
• Both vertical and horizontal outlets included
• Fast delivery

The ProRate PLUS-L feeder is designed for gravimetric feeding of free flowing bulk solids that do not require agitation. It is ideal for feeding pellets in the plastics industry. The single screw feeder with extension hopper is suspended on a two-point weighing system in a compact frame. Proven Smart Force Transducer (SFT) weighing technology provides accurate and reliable performance.

P-SFT Smart Force Transducer load cells, operating under compression,provide accurate, stable and reliable digital weight measurement under a broad range of operating conditions.
The P-SFT exploits the dependency of a vibrating wire's resonant frequency on its tension to measure applied loads. Through mechanical means the applied load is transmitted to the wire, causing a change in its resonant frequency from which the weight of the applied load is computed by the onboard microprocessor. A fully calibrated (linearized, spanned and temperature compensated) signal is transmitted via RS 485 serial communication to the controller.

With the ProRate PLUS control system each feeder has its own PCM control module, installed directly at the feeder. In a line setting, up to eight feeders can be controlled from one PCM-KD. Connection between feeders and operator interface is via an industrial network. All setup, diagnostics and operator interface functions are controlled via a the PCM-KD interface. With its tight integration into the feeder, the PCM can be pre-wired and pre-tested in the manufacturing plant.

Two models are available:

• The PCM-KD features an operator interface with keypad and LCD display in addition to a motor drive for one feeder. The control and motor drive module are combined into one component and are integrated directly into the feeder. The PCM-KD also features simple line control functionality: up to eight feeders can be controlled from one PCM-KD.
• The PCM-MD is a single feeder motor drive unit with no operator interface. The PCM-MD must be connected to a PCM-KD in order to control the feeder.
