  • Additional Information
  • WT4000 Industrial Weight Indicator, Built-in Applications

    The W&M approved WT4000 Weight Indicator is designed for applications in the chemical and pharmaceutical industry, in the food industry and in many other sectors of industry. The industrial design with the modular hardware and the powerful standard programs make the WT4000 the ideal choice for:

    • Weigh and print applications 
    • Parts counting 
    • Vehicle weighing
    • Checkweighing
    • Filling Mobile data capture systems.
    Weigh and print terminal (BASIC)
    Capturing of W&M approved weight from one or two scales (e.g. floor, bench, overhead track scale), entry of additional IDs via keyboard or cable / wireless scanner. Transmission of all data to the host system over Ethernet or WLAN. W&M approved data archive in the WT4000 or on a PC.
    Parts counting terminal (COUNT)

    Capturing of piece weight via reference scale, parts counting in weigh-in or weigh-out mode, bar graph display, configurable printout, and data transmission. With article file, item counter, memory for totals, automatic taring, plus / minus check and many more functions.

    Setpoint controller (CONTROL)

    Controlling setpoints at hopper or platform scales.

    Remote-controlled weighing terminal (ONLINE)

    Remote control of all weighing, display, and printing functions with PC commands via Ethernet. Weight data storage in internal Alibi memory.

    Filling controller (only for non-automatic scales)

    Fast and precise two-speed filling of solid materials with preact optimization. Files for product parameters and statistics for 10 products. Data backup and remote diagnosis possible with an integrated web server over Ethernet.

    W&M approved vehicle scale First, second and single-pass weighing, entry of IDs, internal W&M approved data archive, configurable print format, data transmission over Ethernet. Optional connection of remote displays, traffic lights and full-size PC keyboard. In ONLINE mode full remote control possible from PC (with W&M approved data storage either in WT4000 or on PC).

    The W&M approved WT4000 weight Indicator is designed for applications in the chemical and pharmaceutical industry, in the food industry and in many other sectors of industry. The industrial design with the modular hardware and the powerful standard programs make the WT4 weight Indicator the ideal choice for your application

    Simple integration

    • Connection to scales with analog strain gauge load cells, 
    • entry impedance 43 Ohm–3.3 kOhm (e.g. suitable for 8 x 350 Ohm load cells), or via zener barriers, 
    • entry impedance 87.5 Ohm–3.3 kOhm (e.g. suitable for 4 x 350 Ohm load cells), 
    • W&M approved resolution of up to 6,000 d at a max. of 80 % preload,
    • internal resolution 524,000 d, update rate selectable 50–800 updates / second, 
    • smallest load cell signal 0.33 mV/e. 
    • Optional connection of two scale bases via DUAL-ADM. Optional connection of digital scales.


    Clear-text operator prompting. Set up as a single or multiple-range scale with 1, 2 or 3 ranges or as multi-interval scale. Calibration with test weights or by the entry of rated output of load cell(s), option for the linearization of the load curve with up to 6 linearization points.

    Electrical connection
