The Enclosure

The "Belt-Way" control is housed in a rugged NEMA 4X, corrosion-resistant fibreglass enclosure. A power supply is included for use with 120 volt AC or 220 volt AC. Direct connection to 12 volt DC or 24 volt DC requires no modification (just eliminate the power supply).

4 line by 20 character display. The standard vacuum fluorescent display is easy to read and provides accumulated weight, current production rate (in English, or metric tons per hour), belt speed, and % load on the scale. Master totals, calibration settings and a wide variety of information on your production is available at the touch of a button.

What's inside?

Data Collection

Log data to a printer, PC, modem, or scoreboard style display using our standard RS-232 output.

The "Belt-Way" Network

Lightning fast and easy to use, the "Belt-Way" network transmits information via a coaxial cable. Collect data from one, or multiple scales to monitor production on site or connect a modem to the "Belt-Way" remote display and monitor production from anywhere! Any PC with Microsoft windows 95, 98, WIN2K or XP will interface with the "Belt-Way" control directly. No additional software is required.

Auto Zero Function

Automatically compensates for variance due to build-up of material on the empty belt, or changes in belt tension due to temperature, etc.

Optional 2 Channel I/O Board

1. Pulse Output - Use the pulse output to a PLC or remote counter to integrate "Belt-Way" scales with your existing system - Quadrature waveform included.

2. Load-Out Systems - Program up to eight preset lead weights and print a ticket if desired. Add a "Belt-Way" remote start/stop station for easy, accurate loading.

3. Drive a Chart Recorder - Use one of the analog outputs to record the actual rate crossing the scale on the chart recorder.

4. Control Feed Rate - Use the P.I.D loop control feature to program a desired flow rate. The scale will control the flow rate using one of the analog outputs.

5. Open Loop Blending - Use up to four analog outputs to control up to four ingredients added to the material crossing the belt scale. Note - use of an open loop system does not monitor flow rates of additives.

6. Closed Loop Blending - Closed loop blending uses a scale, or flow meter, to measure the flow rate of each additive. P.I.D. loop control is often used to control the flow rate of the main scale on the network, as well as the proportion of each additive.

Solid Impact Flow Meter

Using the built in network and P.I.D. control loop, a controlled amount of ingredient may be added to material crossing a belt scale or material flowing through another flow meter. Each control includes a network interface that can be used to connect several flow meters to "Belt-Way" Conveyor Belt Scales. Material Flows down a tube and strikes an impact plate that is supported by two single point suspension load cells.
