This article is based on an actual question asked by a potential customer*:
In the technical data of the Kern DE scale the dimensions are given as follows: 318 x 308 x 75 mm. I would like to know how high the scale is when it is standing on a straight surface, i.e. whether anything needs to be added to the 75 mm height.
Although I was not quite sure what the last sentence meant, I took the opportunity to confirm the height of the base of this scale. The Kern DE 60K10D I measured was around 77 mm high:
This is not much, but we sell an even thinner compact platform scale: The smallest scales in the Ohaus Catapult 5000 series are specified as 310 x 270 x 40 mm. The C51XE30R I measured was only around 42 to 43 mm thick:
While the base of the R-series Ohaus Catapult 5000 models is super slim, please note that the indicator is relatively bulky and that the stainless steel platform is not removable:
Another option would be the simpler Ohaus SD scales, which are also around 42 mm high (most compact models).
Thin scales can be advantageous if you plan to integrate them into a packing table (or other type of furniture), but keep in mind that they may not be as robust and serviceable as larger platform scales.
Two versions of Kern’s BalanceConnection software are now available: the standard version (SCD-4.0) and the Pro version (SCD-4.0-PRO).
The following table shows the features of the standard version on the left and the additional features of the Pro version on the right (according to Kern’s 2019 catalog):
· For operating systems Windows XP, Vista, 7, 8, 8.1, 10 · Supports balances measuring devices with RS 232, RS 485, Bluetooth, LAN or WLAN network (TCP/UDP/IP) · Highly flexible formatting of the output (any order, formatting and rounding), particularly recording of date and time for every value transferred, if required · Any number of devices/interfaces can be connected, as well as simultaneous and synchronised recording of several balances · Key-activated or time-controlled interro- gation of measurements or trigger of device functions, also for continuous recording · The interface protocols for KERN balances are already predefined (standard configuration) · Compatible interface cable included when you order a KERN balance at the same time · Many different transfer and recording options: – Microsoft ® Excel/Access/Word in the fore ground or background – Other Windows applications (through key simulation), e.g. shipping software or ERP system (SAP, Sage, etc.) – File recording (e.g. as text or CSV file) – Print out on text or label printer – Screen output such as large display, line chart (drying curve for moisture analyzer), histogram, etc.
· ODBC/SQL databases such as SQL Server or MySQL · Transfer to HTTP Webservices/Web forms · Histogram · Enables the connection of medical balances to practice EDP systems using the device data transfer protocol (GDT) and also the HL7 protocol · Implementation of programs/scrips using freely-definable command lines · Command sequences · Defining the conditions for specific events and the reaction to these events · Filter for stability recognition (configurable value storage) · Central configuration repository, e.g. on the network · On-screen displays with configurable user interface for flexible balance operation
If you do not need the features listed on the right, the standard version is the right choice. However, this version has also become a bit more expensive compared to the single version available so far.
If you don’t need the extensive functionality of BalanceConnection and only want to connect a single scale to your PC, we offer two very inexpensive alternatives. Each of these programs has a single purpose and is therefore easy to set up and use:
232key: Transfers the weight to any application (e.g. Excel, shipping software, etc.) using a key simulation (virtual keyboard wedge).
Simple Data Logger: Stores the weight in a CSV file (if desired with date and time), the weight can also be retrieved from the scale using a timer (Plus version only).
A&D has confirmed that the SJ-WP series of compact bench scales is going on sale in Europe in the first quarter of 2014.
To understand what’s so ingenious about this scale, you should know that until now, compact scales were either fast or they had a high degree of ingress protection. It was not possible to have both a very short stabilization time (<1s) and resistance to dust and liquids in a compact instrument. The reason for this is that the air pressure inside the housing of the scale changes when a load is applied (or removed). For accurate measurements, the air pressure inside and outside has to be equalized. Of course, this could be achieved by simply building a few holes into the housing, but then you would allow dust and liquids to enter. The conventional solution has been to use selectively permeable membranes which let air through and block water. However, air diffusion through these membranes takes time, slowing down the measurement process.
A&D’s new approach is remarkably simple and effective: By mounting the load cell outside of the housing, the SJ-WP scale achieves a stabilization time of 0.5s or less in combination with IP67 protection (dust tight and water proof up to 1m):
Fast, compact, resistant to harsh environments and easy to clean, A&D’s SJ-WP could be a game changer in the food industry.
While I have no information on new products coming in 2014 yet, I was told that Adam is planning to add USB host functionality to a number of balances. This would allow weighing data to be written directly on a memory stick, greatly simplifying data logging and data transfer to a computer. This functionality is already available on Adam’s PMB moisture analyzer:
The first pages of the 2014 catalog show Kern’s continued focus on touchscreen scales. The new models include analytical and precision balances as well as platform scales. While Kern does not indicate who the ODM is, I’m pretty sure these devices are made by Radwag in Poland.
A cooperation between the two companies would make sense: Kern’s strengths are sales and marketing, while Radwag is good at actually developing and manufacturing weighing instruments.
The new Valor 2000 and 4000 are aimed at the food industry and are meant to improve productivity even in harsh environments. There are still some inconsistencies in the available documents but it appears that Ohaus is claiming a stabilization time of 0.5s with an IPX8 rating (no dust ingress protection; protected against submersion beyond 1m).
If you’ve read this post from the very beginning, you might be wondering how Ohaus has been able to achieve this with a load cell that’s placed inside the housing. The answer is called “Flow-Through Design” and simply means that there are indeed some holes in the housing which allow air and liquids to enter and exit relatively unhindered. The electronic components are silicon sealed to protect them from fluids and condensation:
I’m looking forward to comparing this approach with A&D’s external load cell solution.
Update March 2014: Ohaus has released a video featuring the new scales:
Our software is designed to make it easier to transfer measurement values from any instrument with an RS-232 interface to any application which accepts keyboard input. It receives data from a scale, balance or other device via RS-232 (COM port), extracts the numeric value, formats it and “types” it into another program (“keyboard wedge”-functionality). I’ll announce the release on this blog.
