Weigh Controller

Kehkashan Automation offers a Weigh Controller, Model PR444S. The PR444S connects with a single set of 1 to 4 strain gauge load cells. It supplies 10 V DC excitation and amplifies and conditions the resultant return signal. From this signal and from stored control and calibration data it accurately controls the repetitive weighing-in or weighing-out of target quantities of material. Access to the control and calibration data is pass-number protected. The PR444S can be started, stopped and when necessary reset, by using the three digital inputs either under automatic control from other equipment or from external pushbuttons. Digital inputs can operate from 110-240 V AC nominal control supplies, or 18-30 V DC in the case of the DC powered version PR444S-D. Digital outputs are volt-free relay contacts with one common connection and can switch up to 240 V AC or 30 V DC loads. The RS232 serial link can be configured to produce formatted batch reports on a 24-column (minimum) printer or for two-way communication with a computer or PLC. Applications: for pharmaceuticals, food processing, pulp and paper, chemical, solvent extraction and cement, etc. Features: ideal for jar, carton, check weighing, feed in, feed out, sack and bulk container filling; load cell weighing accurate to 16,000 divisions (65,000 divisions internal resolution); weighing-in, weighing-out and through-put modes; two speed feed control plus either discharge if weighing-in or top-up if weighing-out; automatic in-flight compensation; pushbutton calibration; and printer or PC/PLC serial communications output.
