Description

The weight processor PW-310 is a universal multifunctional module purposed for measure a signal from analog load cells, its mathematical processing and transformation according to a given program. In accordance with the results of this processing and analysis of the states of discrete inputs, PW-310 generates control signals at its outputs (discrete and analog), which ensure the operation of scales for various purposes:

Hopper scales;
Belt scales;
Batchers of discrete action and filling equipment;
Belt feeders;
Bag accounting systems and other specialized weighing systems.

The weight processor PW-310 has an increased protection index and can operate in harsh industrial conditions (dust, moisture, temperature drops).

The feature of the module is a simple, clear and friendly interface with the user with only 4 control buttons.

Functions of the weight processor PW-310 for the hopper scales SWEDA WBA:

control of a two-position (“coarse – fine”) loading and unloading mechanism;
control of the position of actuators by external discrete signals;
simple calibration of the module both with reference weights and according to the WTR of load cells.
external discrete signals for controlling the position of actuators;
maintaining the specified capacity of the flow of material;
shipment of a controlled amount of material, including with a specified capacity.
