Know Instantly Whether Your Water Is Safe to Drink


 

 

In 2018, access to clean water should be a given. It's not. Over 2.1 billion people live without safely managed water services. Meanwhile, contaminated water continues to transmit diseases - diarrhea, cholera, dysentery, typhoid, and polio.

 

What if you could easily determine whether your drinking water was safe? Now you can. A small device by Lishtot analyzes the electric field around water and instantly determines if it is safe to drink. 

 

Having the ability to check whether or not your water is clean will not solve the world's water problem, but it is a step in the right direction.

Choose A Conveyor Belt Scale Location Carefully
Do's and Don'ts

You rely on the accuracy of your belt scale to monitor process efficiency and quality. Did you know that the reliability you depend on is heavily impacted by the location of your conveyor belt install?

For accurate measurements, carefully select the best location to install the belt scale.

1. DON'T install the scale near the conveyor loading point. Turbulence leads to poor performance and accuracy. Wait to weigh materials until they completely settle, at least one or two conveyor idlers away from where turbulence stops. For the same reason, avoid installs near the conveyors head pulley or tail pulley.

2. DO install the conveyor belt scale in an area with constant belt tension. Because it acts as a force on the scale, belt tension is factored out during calibration. Tension variations will affect accuracy. If belt tension variances are a continuing problem, talk with your belt scale manufacturer about a tensioning device.

3. 
DON'T install on a steep incline. 
Angles of more than 15 deg greatly increase the chance of material roll back, causing the material to be weighed multiple times. Inequality between belt speed and material feed velocity may also cause roll back.

4. DON'T
install the belt scale where the conveyor forms a convex or concave curve.
The belt could lift up from the curve preventing a solid, empty belt zero balance.

5. DO 
isolate
the belt scale from vibratory equipment. 
The vibration from crushers, vibratory feeding equipment and hammer mills can negatively affect the belt scale. 

6. DO consider weather conditions.  Temperatures below -20 degrees C can cause ice and frost build-up on the belt, creating less reliable speed sensing. Check with your belt scale manufacturer.
Tecweigh Belt Scales in Single, Dual and Four Idler Configurations
Dependable and Durable


  
WY-10
The WY-10 scales routinely handle flow rates in excess of 10,000 tons per hour. The weather-tight, one piece construction withstands extreme conditions including dust, dirt and harsh weather. Internal LVDT load sensors prevent overloading. A self-storing calibration weight makes calibration easy and safe, eliminating cumbersome hang-on weights.

Features
  • Single Idler Scale ± 1/2% Accuracy
  • Dual Idler Scale ± 1/4% Accuracy
  • Four Idler Scale ± 1/8% Accuracy
  • Fully Welded Frames
  • Standard Belt Widths 18" - 96"
  • Rugged Steel Carriage
  • Self-Storing Calibration Weights
  • User-Friendly Electronic Weigh Processor
  • 5 year warranty - longest in the Industry

 
WY-15
Made from carbon steel, The WY-15 features one-piece welded construction and twoprecision NTEP approved strain gauge load cells. Already capable of weathering extreme condition, the scale can also be customized for explosion proof applications. Options include food grade, plated and stainless steel.

Features
  • Single Idler Scale ± 1/2% Accuracy
  • Dual Idler Scale ± 1/4% Accuracy
  • Four Idler Scale ± 1/8% Accuracy
  • Fully Welded Frames
  • Standard Belt Widths 18" - 72"
  • Mechanical Overload Protection 
  • Rugged Steel Carriage
  • Self-Storing Calibration Weights
  • User-Friendly Electronic Weigh Processor
  • 5 year warranty - longest in the Industry
Options for both the WY-10 and the WY-15 include:
  • Wireless Communication
  • Chart Recorders
  • Ticket/Tape Printers
  • Remote Rate/Total Displays
  • Scoreboard Displays
  • Industrial Network Communication Protocols (Ethernet, Profibus, DeviceNet, Modbus RTU & others)
     
HY- 15 Hybrid Belt Scale
Designed to incorporate Tecweigh's electronics package with a less costly modular scale frame design, the HY-15 is a cost-effective hybrid belt scale. The compact, low profile design is suitable for many conveyor applications including non-standard belt widths and mobile applications. 

The HY-15 offers a unique weighing design - one module is a rigid mount from the idler to the load cell, while the other incorporates a forgiving spherical bearing to greatly reduce drift problems caused by flexing structures.

Features
  • Heavy-Duty Cold Rolled Steel Modules (one rigid mount, and one spherical bearing mount - flex module)
  • Hardware Provisions (to modify flex module into a rigid configuration)
  • Low Profile and Compact Design
  • Simplified Design for Quick and Easy Installation
  • Two (2) Precision NTEP Approved Strain Guage Load Cells
  • Signal Conditioning Board in NEMA 12 Enclosure
  • Tail Pulley Mounted Speed Sensor with 25' of Cable
  • Mechanical Overload Protection
  • ½ -1% Accuracy (with single-idler HY15 Model)
  • Mounting Brackets for Static Weight Calibration
  • Installation Kit
