KERN & SOHN: PROFESSIONAL MEASUREMENT since 1844
The KERN brand has stood for precision and reliability for more than 180 years. With over 5,000 products, the family-owned business offers a comprehensive range of scales, microscopes, and measuring devices, complemented by specialized software and services. Company founder Gottlieb Kern built the most precise scales of his time in Baden-Württemberg in 1844. Since then, Germany's oldest precision scale manufacturer has evolved into a powerful full-service provider of measurement and weighing technology. KERN's extensive range of medical technology products includes everything from user-friendly scales and microscopes for everyday use in clinics and hospitals to highly specialized models, such as those designed for laboratory applications. Across all products, KERN places great importance on user-friendly, intuitive operation—reducing the workload of specialists and ultimately benefiting patients.
Definition of the KERN IoT-Line:
KERN IoT-Line balances – the name says it all:
They are more than just scales, they function as compact industrial PCs. They set new standards with their exceptional ability for universal data connection and bidirectional communication. Their communication capabilities far exceed those of conventional scales and enable seamless integration with PCs and machines. Bidirectionality: KERN IoT scales can not only output a wide range of data types, but can also simultaneously receive external commands and input data, such as the tare weight, and process them directly. All functions are clearly described in the standardized KCP protocol (see interface protocol on the webshop)
Integrate your IoT scale into your target system:
ERP systems
Production management systems
Quality control systems
Patient management systems
MS Excel
How does the weighing data get into your target system?
We offer three options for capturing and processing transaction data for your target system:
KERN Communication Protocol KCP: The scale is connected "directly" to the target system. The target system requests the weighing result via the KCP protocol.
KERN Software Balance Connection: The application records weighing data, adds date, time, user, etc. to it if necessary and forwards it to the target system via key simulation, or saves the data directly in an Excel, CSV oder log file.
KERN Software EasyTouch: The application combines weighing data with a variety of object data and thus generates process results such as counting results, recipe data, an test reports, and it stores them in a tamper-proof central database, which can then be further processed in the target system.
KERN Universal Port (KUP)(KUP) in combination with the KERN Universal Module (KUM)
The KERN Universal Port (KUP) enables the connection of external KUP interface adapters, such as RS-232, USB, Bluetooth, Wi-Fi, analog, Ethernet, etc.
The outstanding advantage here is that the KUP interface adapters are simply plugged on, i.e. interfaces can be conveniently replaced and retrofitted without opening the scale housing or any complicated installation.
The interface adapters enable convenient transfer of weighing data to networks, PCs, smartphones, tablets, laptops, printers, etc. In addition, control commands and data inputs can also be sent to the scale via the connected devices.
The KERN Universal Module (KUM) is already installed in the operating terminal of platform, floor and pallet scales. Especially for use in moisture or dust-protected areas up to IP68, a connection via Bluetooth or Wi-Fi is recommended to avoid opening the terminal.
Tip: With the KERN KUP-13 extension box, up to three interfaces can be operated in parallel on the scale.
What interfaces do the KERN IoT scales have?
KERN IoT balances offer universal connectivity thanks to the flexible options with KUP (KERN Universal Port) and KUM (KERN Universal Module). These enable seamless integration into a wide range of systems and applications.
KCP: The data highway of the scale
The KERN Communication Protocol (KCP) enables the scale to be queried and remotely controlled via computer or CRM/ERP systems. The KCP is a standardized interface command set for KERN scales and other measuring instruments, which allows all relevant parameters and device functions to be accessed and controlled. KERN models from the IoT-line with KCP can therefore be easily connected
to computers, industrial control systems, and other digital systems.
The KERN Communication Protocol is largely compatible with the MT-SICS protocol. The KCP is available via all KUPs and KUMs.
KCP – Export ("Outbound")
stable and immediate weight
live transmission of the weights
storage of gross, tare and net weights, stability feature, date, time, etc., in the tamper-proof alibi memory
output of the weight in all available units, percent, and a free factor
output of the weight in items (piece-counting function)
output of the weight at freely definable intervals
and much more
KCP – Import ("Inbound")
