Often you will see NTEP Legal for Trade Class III listed as the approval of a digital scale. But, what exactly does Class III mean? Handbook 44, the book that spells out rules and regulations for the weighing industry, separates weighing devices into five accuracy classes. Depending on the number and value of scale divisions, equipment can be either class I, II, III, IIIL, or IIII, with Class I having the highest precision. All Legal-for-Trade scales fall under one of these five classes.
Table 7a of Handbook 44 breaks down the description of each class. Class III states: "All commercial weighing not otherwise specified, grain test scales, retail precious metals and semi-precious gem weighing, animal scales, postal scales, vehicle on-board weighing systems with a capacity less than or equal to 30,000 lb, and scales used to determine laundry charges."
So what it's saying is basically anything that doesn’t fall elsewhere would go in class 3. Providing the device meets the basic criteria for the quantity and size of divisions. Class III actually covers many different types of scales. Retail scales would be one type of Class III application. While some jewelry scales are Class III if the resolution is appropriate for the application, a more precise jewelry scale could be Class II. It all depends on the number of divisions and capacity. Precision laboratory devices fall under Class I. Click here to read more.
Cardinal Scale's new USB-A option card offers customers exciting new connectivity possibilities! The 2XX-USBA is compatible with Cardinal Scale indicator model numbers 205, 210, 212G, and 225 indicators and provides you with two USB-A ports and one micro SD port. Both USB ports and the micro SD port may all be used simultaneously. For instance, a USB drive may be recording transactions while the other USB port is connected to a 101 keyboard at the same time that a micro SD card is storing IDs. See more by clicking here.
Here is another example to consider. With one 4GB flash drive, you could literally collect millions of weight transactions using the Cardinal Scale digital weight indicator. Then once you’re ready to view the transactions, you remove the flash drive and take a look at the CSV file on your computer. It’s easy to add titles to the columns and sum the weight column to determine the total amount of weight that you’ve weighed over a period of time.
These Cardinal Scale digital weight indicators can be connected and calibrated to many different types of weighing systems and scales in the market today. If you've done any research on sending weight data to the PC you know that there are options out there. But, most provide data collection software in real time and need the ability to connect the scale to your company network typically through an Ethernet connection. Those are certainly good systems but, if you’re just looking for the ability to collect weight data that can easily be collected on a USB thumb drive and then inserted into your PC, then you need to take a look at the Cardinal Scale product line for a simple solution. Once you insert the USB flash drive into your computer, you can analyze and manipulate the data as you see fit using Excel spreadsheet software which most everyone seems to have these days.
E-mail alerts may be assigned for up to three of the presets per scale. For instance, e-mail alerts might be sent for Over, Under, (Reorder), and Extremely Low, but not for the unnecessary Accept weight status. Additionally, up to three recipients per scale may receive each e-mail alert via separate e-mail addresses.
The product is the OHAUS MB Series Moisture Analyzer, which combines state-of-the-art halogen heating with highly accurate weighing technology to revolutionize the process of determining solids content and ensuring compliance with regulations. With a minimal investment, the moisture analyzers have helped several wastewater and treatment facilities in New York and New Jersey by vastly improving speed, accuracy and reliability.
Basically the moisture analyzer helps treatment facilities get total solids analysis of sludge during the dewatering process. Accuracy is important and since the moisture analyzers are easier to use than traditional methods, human error is reduced.
How The Process Works
During the treatment process, wastewater is tested numerous times for solids percentage. When using traditional heating ovens, solids percentage testing can be incredibly time consuming and inefficient, taking up to several hours to complete a single test. At the facilities in New York and New Jersey where the traditional ovens were replaced with OHAUS MB Series Moisture Analyzers, the process for testing a sample is now accomplished in less than 30 minutes.
The MB series can be easily and efficiently used at numerous points throughout the testing process to determine the effectiveness of the thickening process and dewatering of the sludge. Testing can be completed in batch processing before the wastewater/sludge is moved to each of the next steps. In the overall treatment process, this kind of continuous process testing enabled by the MB Series ensures the most accurate readings and safe levels of solids content for digestion by plant and animal life throughout the environment. Testing during the dewatering process ensures the sludge will meet the solids content minimums for landfill disposal or use as a fertilizer. To optimize accuracy, all testing and weighing occurs inside the heating chamber of the MB Series, which is protected from cross drafts and other outside factors.
Unlike conventional ovens that force the user to remove the sample to be weighed, the end result when using the MB Series is immediately recorded so that environmental moisture does not re-enter the sample, skewing the results. The MB Series also provides uniformed infrared halogen heating up to 200°C, readability up to 1mg, 0.01% moisture and a 45g capacity. The ability to measure smaller samples also increases the MB Series' effectiveness in providing more accurate results of test samples.
Additional Benefit of Cost Savings By incorporating the MB Series into their treatment process, Wastewater Treatment Plants also have been able to significantly reduce their bottom lines. In addition to costing less and needing less repair and service than traditional ovens, the increased accuracy provided by the MB Series enables wastewater and treatment facilities to better remove unneeded, excess water from the dry solid waste they transport. The reduction in water lessens the weight of the load thereby reducing the cost of transportation.
Unlike large laboratory ovens, the MB Series can escape the confines of the lab and be used throughout the plant or facility and essentially take up significantly less space then an oven or conventional microwave heating chamber. Most importantly; however, the MB Series Moisture Analyzers optimize the efficiency of the treatment process, even during significant flow events.
