Masterweigh® 6

Masterweigh® 6 is a precision, is a microprocessor based electronic integrator.

Modular in design, comprising Main Processor and Power supply boards mounted in a Nema 4 enclosure, the system is easily field serviceable.

Masterweigh® 6 has been designed to be used with Web-Tech's range of conveyor belt scales, weigh belt feeders and weighing screw feeders. However it is an ideal replacement for older load cell based installations, manufactured by others.

Features which are considered "options" with other manufacturer's products are standard on Masterweigh® 6

Easy Set Up and Calibration

A sixteen.key keypad is used to enter calibration data, as well as to access Masterweigh's menu. Load cell outputs and tachometer / magnetic pickup output frequencies can be viewed from specific entries within the menu, without interrupting the normal operation of Masterweigh® 6.

The ability to view this data during the system's initial setup provides commissioning engineers with useful data for future use in the unlikely event that the system fails.

Because Masterweigh® 6 calibration procedures are menu driven and prompts are full English statements, adjustments to any parameters are easily accomplished by just a few key strokes.

Data pertaining to any calibration can be recorded automatically by connecting a printer (optional extra) to the RS 232 port and initiating the print menu depending on software installed.

Load and Speed Detection

Load cells of varying output ranges can be used, making Masterweigh® the obvious choice when contemplating updating older scales.

A wide range of belt speed encoders can be employed with outputs ranging from a minimum of 2.5V to 50V.

Magnetic pick.up devices are easily utilised with no changes to Masterweigh® or the magnetic pick.up. Where a preference is shown for precision high speed and high resolution.

Web-Tech manufactures a range of industrially hardened optical encoders. High quality seals and bearings ensure that the device will perform under the harshest of industrial conditions providing the user with reliable and long term service. An optional stainless steel housing is available.

Display

All local information, mass rate and accumulation, is displayed on a 2 x 40 character liquid crystal display. All data is displayed in English. Codes and hieroglyphics are not used therefore operators are less likely to be confused when calibrating or interrogating the system.

Outputs for Remote Counters and Displays

Masterweigh® has outputs which allow it to communicate with a wide varies, of displays and controls.

A 4-20mA current loop (externally powered or Masterweigh® driven' provides a proportional rate signal This signal can be used to drive analogue or digital rate meters or to provide rate data to PLC etc.
