The EC 120 processing unit is the ideal central unit developed for HAENNI weighing systems, perfectly suited for operation under the harshest environmental conditions. This compact and reliable device enables the simple, fast display, storage, and printing of loads measured by HAENNI digital interface scales. The EC 120 is particularly recommended for those seeking a simple yet professional solution for managing axle and wheel load data, whether for static or dynamic measurements.
The main advantage of the device is its wireless communication capability, which provides flexibility during installation and measurement, minimizing the inconvenience associated with cabling. The robust design and IP67 protection guarantee a long service life and reliable operation even in extreme conditions.
The EC 120 processing unit provides precise and reliable performance based on the following technical parameters:

The EC 120 plays a central role in the measurement process. It is capable of receiving digital data from HAENNI measuring units (e.g., WL 101, WL 104, WL 108), whether it concerns single wheel loads, axle loads, or even the total weight of the vehicle. The built-in memory allows for secure recording of measurement data for later analysis. The user can easily manage partial totals and final gross totals, which is essential during official checks or internal quality assurance processes.
The device offers outstanding flexibility in the area of communication. The wireless connection via (HAENNI Network Protocol – HNP) allows weighing platforms to connect to the unit wirelessly, significantly speeding up setup and reducing the risk of accidents in busy locations. Additionally, it features a cable connection option, ensuring redundancy and a stable connection if the radio transmission is not ideal.
Weighing tasks often take place outdoors, under changing weather conditions. The EC 120 has been designed taking this into account:
The 320 x 240 pixel monochrome LCD display is designed so that it is perfectly readable in bright daylight , which is critical during outdoor measurements. The user interface is intuitive, allowing for quick navigation through stored data and access to printing functions.
The EC 120 supports immediate documentation of measurement results. The Simple protocol definition with templates Users can quickly set the desired print format, which can include the date, time, unique identifiers, as well as the measured axle and total load values. This function is crucial for official records and on-site verifications.
The EC 120 processing unit is an indispensable accessory for HAENNI measuring systems, guaranteeing the accuracy, reliability, and ease of use of the measurement data, even in the most demanding application areas.
