Control Systems
Technical Weighing Services offers more than stand alone scales. We know that
you often have a need for your scale to be an integrated part of a control
package. Some of these applications include Batching, Billet/Bloom, Scrap
Blending for the Steel Industry and the Omni Scale Digital Diagnostic System,
typically used for harsh environments. Other applications are Wireless
Communications, Concrete, and Asphalt Batching using Hoppers, Truck or Rail
scales. Your process may be a simple application with analog or serial signals,
or stand alone batching systems for the food and material handling industries.
We also integrate scales with computers to interface with your level 2 control
systems. See some examples below for an idea of what we can do for you. Most
applications are custom designed for your specific needs.
Batching
Billet Weigh
With Torch Cutting Controls
- Torch Control: Integrated torch control and automatic length compensation. Variation to target is statistically analyzed to provide next cut pre-action.
- Reliable Length Control Implementing Better Sensor Technology: Measure by contact roll resolver (eliminates failure-prone encoder electrical and mechanical problems), or contact-less long-range laser range finder technology.
-
Selection of Cut an Optimization Method:
Cut by length or cut by weight.
Metallurgy entered in system parameters interacts with length calculation.-
Integrated Weigh Electronics:
Our use of tightly-integrated PLC-based
weigh modules allow fast, easy setup and calibration to flow within the
operator GUI: no need to "crack the book" or fuss with cumbersome calibration
routines or third party black boxes. PLC stored calibration values reset to
original upon module change-out.
- PLC Based System with Open or Dedicated:
GUI for Operator
interface to your plant standards.- Check Weigh Mechanicals
Suit your Line Arrangement:
Pick and Weigh (overhead: low maintenance);
Lift & Weigh or Set-Aside and Weigh. Weigh data is compared to length data and
chemistry for accurate statistical cut control using our proven algorithms.
- Statistics:
Graphically track length, weight, shift uptime
and productivity. Generate hardcopy or report to your Level 2 system via
plant or industrial net. TWS can even provide ties to company MIS and
Production Orders System and financials. Know your cost and get the data
real-time!
Scrap Charge Management
- "Chargemate"
Accurate weighing on your transfer car, rail car, or
static bucket scale.
Reliable Radio Modem communication of weights to crane cab.
Durable Touch Screen Operator display in crane cab:
- Constant display of current scrap net weight
- Easy operator selection of scrap type being loaded, and heat/bucket Ids
- Bucket and Heat current scrap loaded totals, displayed by grade
- Optional Recipe display
Recording and storage of weights loaded, by grade, for
bucket and heat.
Optional link to level 2 systems for downloading weights,
and uploading recipes.
Can handle multiple crane applications.
Omni Scale
Wireless, Industrial, Multi-Load Cell Weighing and Diagnostics
If you have a load cell based weighing system in a harsh, difficult to troubleshoot
environment, then OmniScale provides an alternative to traditional weighing instrumentation.
The OmniScale system consists of a multi-channel high-resolution digitizer located at the load
cells, and a PC based software package located remotely that is the weight indicator. Since the
digitizer converts each load cell individually, and sends the data back to the OmniScale PC for
totalizing, calibration, individual Load Cell diagnostics and troubleshooting can be done
remotely. Since the connection between the OmniScale Digitizer, and OmniScale PC is a simple
serial link, you no longer have to worry about the reliability of running low voltage load cell
cables long distances. Also, TWS's optional Spread Spectrum Radio Link communications is perfect
for moving machinery applications, because it eliminates any cabling between the load cells and the readout.
Accurate high resolution weighing in harsh environments.
Up to 4 Load Cells can be individually digitized at the scale with industrialized electronics.
PC based scale software allows remote calibration and individual Load Cell Diagnostics.
Load Cells can be individually disconnected in software for troubleshooting without having to physically go to the scale, and calibration will be retained.
Wireless communications eliminate cables between the load cells and the weight indication.
Multiple OmniScale software packages can run on one PC.
OmniScale PC can connect to other systems via RS232 serial links, Ethernet, or a variety of PLC vendor network interfaces.
