HBK launches PW22i load cell for fast packaging lines
HBK has introduced the PW22i single-point load cell for high-dynamic industrial systems, targeting packaging lines and robotic applications.
The sensor is designed for environments where weighing systems must run at high speed while delivering repeatable measurements under changing load conditions. Intended applications include multi-head combination weighers, dynamic filling processes and robotic systems exposed to variable load profiles.
The launch reflects growing demand from manufacturers for shorter cycle times, higher throughput and closer monitoring of production equipment. In these settings, weighing systems are increasingly expected to feed process data directly into automation and control systems rather than serve only as a basic checkpoint.
Sensor-level link
A central feature of the PW22i is an integrated IO-Link interface at the sensor level. This allows weighing data to connect directly to the control layer, helping simplify installation and use within existing automation architectures.
The standardised IO-Link interface and M12 four-pin connector are intended to ease commissioning, replacement and retrofit work. Built-in functions include data preprocessing, self-monitoring and diagnostics, giving operators visibility into sensor condition and process behaviour.
These functions are relevant for manufacturers seeking to improve Overall Equipment Effectiveness, particularly in operations where downtime, measurement drift or unplanned maintenance can affect output. The product is suited to both packaging lines and robotic cells, including end-of-arm tooling systems.
Fast response
HBK says the PW22i has high mechanical stiffness and a high natural resonant frequency, resulting in a short settling time. In practice, this matters in applications where equipment must complete weighing tasks quickly before moving to the next cycle.
That can support more precise and repeatable measurements in packaging processes and help maintain stability in robotic systems working under dynamic loads. The sensor is available in 10 kg, 20 kg and 50 kg versions and carries C3MR accuracy classification.
Industrial users are also under pressure to ensure equipment can withstand mechanical stress in production settings. The PW22i has IP67 protection and includes a patented overload stop that allows it to withstand up to five times its nominal capacity.
This design is intended to support operation under eccentric loading and transient forces, conditions common in automated machinery and robotics. Such resilience can be important where sensors are exposed to sudden changes in load or repeated physical strain.
Simon Kleefeldt, Product Manager Weighing Sensors at HBK, outlined the intended use cases for the new product.
"The PW22i was designed for environments where mechanical dynamics are high and measurement reliability is critical in real time. Whether in high-speed packaging lines or robotic applications with rapidly changing load profiles, we combine ultra-fast dynamic weighing with IO-Link intelligence directly at sensor level. This enables plug-and-play integration, faster commissioning and direct use of weighing data within existing control architectures," said Kleefeldt.
The release comes as manufacturers and machine builders seek closer integration between field-level devices and factory control systems. Sensors that provide direct diagnostics and process information are becoming more common as production lines grow more automated and operators look for earlier warning of faults.
For system integrators, the appeal lies in reducing the time needed to install and replace components while gathering more information from the same device. For equipment makers, the value may depend on whether such sensors can improve consistency and reduce product giveaway in high-volume processes.
HBK says the PW22i is intended to help machine builders, system integrators and manufacturers design faster, more connected systems for packaging automation and industrial robotics.
