Weighing Review Awards 2023
Nominated for Best Load Cells
HBK PW27A Load Cell
PW27A For Hygienic Weighing
With load cells of the PW27A product series, companies producing and filling food products are well prepared to face all future challenges: Designed for low capacities ranging from 0 to 10kg and 0 to 20kg, the load cells comply with the strict EHEDG specifications and are therefore ideally suited for filling, packing, and weighing beverages and other food products.
Due to the special design of the stainless-steel measuring body in conjunction with the solid stainless-steel pipe housing, the PW27A load cells are hermetically sealed and extremely robust (IP68/IP69K degree of protection). This allows quick and thorough cleaning, even with high-pressure washers. Owing to their integrated and encapsulated overload protection—up to ten times their maximum capacity—the PW27A load cells’ functionality remains unchanged even if someone accidentally steps on them (e.g. when cleaning the machine).
A PW27AP version of the load cell providing a connector for even faster integration is also available.
- Accuracy class: C3 multi-range
- Maximum capacities: 0–10 kg and 0–20 kg
- Degree of protection: IP68/IP69K
Scaime DVS & DVX digital load cells with industrial Ethernet connectivity
SCAIME developped DVX and DVS digital load cells for automated and dynamic weighing applications, such as rotary fillers and checkweighers.
These load cells integrate innovative electronics with a multi-protocol communication interface for connectivity to standard industrial Ethernet networks (PROFINET, EtherNet/IP...). To facilitate their integration into the network and shorten their implementation, the sensors offer a dual Ethernet port with internal switch and a web server for configuration.
DVX and DVS load cells are made of stainless steel with an IP68 / IP69K protection level well suited for wet environments and high-pressure washing. Designed to be integrated into rotary filling machines, they offer high resistance to accidental overloads and lateral forces to withstand rough handling of the bottles.
The EHEDG-certified hygienic design makes the DVS ideal for applications with stringent sanitary standards, such as food and beverage and pharmaceutical industries.
To meet the need for high accuracy at high measurement rates, DVX and DVS load cells incorporate a 24-bit analog-to-digital converter and powerful digital filters to attenuate vibration and mechanical disturbances. The sensors are also equipped with logical inputs/outputs for autonomous process control.
DVX and DVS load cells are available with two software versions dedicated to filling or dynamic checkweighing applications.
- In the filling version, the load cell directly controls the valves and takes over the entire filling process. The filling algorithm is optimized for high-speed rotary fillers.
- In the dynamic checkweighing version, the load cell automatically detects the item to be weighed and calculates its weight, on the fly, with a very high accuracy.
These specialized software programs make it possible to increase weighing rates while reducing control tolerances and thus contribute to the manufacture of more homogeneous products.
Robust, accurate and fast, the DVX and DVS digital load cells ensure the performance and efficiency of packaging machines. With their latest generation electronics integrating Industry 4.0 technologies, they offer a sustainable weighing solution consistent with the digital transformation of industrial companies.
METTLER TOLEDO SLP33xD-IOL Smart Single-Point load cells with integrated PLC connectivity and condition monitoring
METTLER TOLEDO developed a new single-point load cell family for automated weighing applications. The integrated IO-Link interface makes the new smart weighing sensors compatible with any automation control system. The integrated connectivity saves space, reduces system complexity, and allows quick and straightforward
installation. The load cell provides 200 updates per second (200 Hz), which supports highspeed weighing applications. Machine designs can be optimized for high throughput and increased
productivity. Condition monitoring and prioritized alarms (Smart5™) ensure the system is performing as expected and allow quick reaction in case of issues. Load cells are available in OIML R60 C6 and C3 accuracy classes. The best-in-class noise level of the on-board electronics and advanced noise filtering algorithms also make resolutions up to 300’000d possible. The TwinCal™ calibration technology supports loading and unloading applications. This together with onboard filtering and adjustment for temperature changes enable precise weighing results in any application. The new load cell family is available with rated capacities from 10 kg up to 500 kg, and with IP67 ingress protection rating.

Thames Side VC3500 Double Ended Shear Beam Load Cell with Patented MasterMount®
Thames Side’s model VC3500 double-ended shear beam load cell with the patented MasterMount® is the best-in-class solution for silo and hopper weighing systems. The MasterMount® was primarily designed for safe and easy installation without the need for any hydraulic lifting jacks or special tools. While conducting any kind of maintenance work like welding, this particular design removes the need to replace the live cells with dummy cells. Self-captivated pins are used, instead of regular retaining clips to retain the stainless steel VC3500 load cells. The MasterMount® accessory itself provides the lift-off protection, as an alternative to the traditional method of using the load cell for lift-off protection. If required, installation and removal of the load cell can be done in only a few minutes, which saves a huge amount of installation cost.
