Description
S-PW22/C3
Single Point Load Cell: Extremely Fast Weighing with Accuracy Class C3
The PW22 single point load cell is ideally suited for fast, dynamic weighing, for example in multihead combination weighers. With IP67 degree of protection, it is ideal for reliable use in industrial environments, for example filling bulk materials or in many other kinds of filling applications.
The PW22 has uniquely high rigidity and therefore an extremely high natural resonant frequency. This ensures low settling times, which in turn results in extremely short weighing times. With a high maximum scale interval factor and accuracy class C3, it returns reliable and has very precise measurement results. Thanks to the patented overload stop in compressive direction, it can withstand overloads of up to five times the maximum capacity. Available with protective housing, six maximum capacities between 6 kg and 90 kg, and different cable lengths, the PW22 single point load cell comes in an extensive range of versions. It has standard footprint for compatible usage. For even more demanding operating conditions, the PW22 is also available in an explosion-proof ATEX version.
- Accuracy class: C3 Multi Range
- Maximum capacity: 6 kg to 90 kg
- Degree of protection: IP67
Accurate measurements

Product questions
Frequently asked questions
Which S-PW22/C3 capacities are listed on this page?
Listed capacities are 6, 10, 20, and 30 kg at $580 each. Each can be selected in WooCommerce, which displays Add to cart; on-hand quantities are not shown.
Why does the datasheet show a 6–90 kg range?
HBK’s PW22 family spans 6–90 kg; this page lists 6, 10, 20, and 30 kg options.
Is the S-PW22/C3 protected for industrial environments?
The product listing specifies an anodized aluminum body and IP67 protection.
What cable and electrical specifications apply?
The listing gives a 2 m, six-conductor cable, 1.9 mV/V sensitivity, and 400/350-ohm input/output resistance. HBK specifies 1–12 V nominal excitation, 15 V max. Verify amplifier and cable.
Is the S-PW22/C3 interchangeable with HBM PW22/C3?
The product listing describes S-PW22/C3 as interchangeable with HBM PW22/C3 models. Before replacement, match capacity, dimensions, mounting, wiring, electrical specifications, and application requirements.
How should the S-PW22/C3 be mounted and wired?
HBK PW22: 2×M6 per interface, class 10.9, 10 N·m; 20 mm maximum thread reach, 0.1 mm connection-surface flatness, and 400 × 400 mm maximum platform. Secure the cell, spread load evenly, and avoid loading the cable side. Six-wire colors: white signal (+), red signal (−), blue excitation (+), black excitation (−), green sense (+), gray sense (−), yellow shield/body. For four-wire amplifiers, connect sense to matching excitation. Confirm this S-PW22/C3 cable. See the HBK PW22 manufacturer datasheet.
