Your end-of-line inspector blinks. In that half-second, a 0.5 g shortfall slips past, ships to a customer, and comes back as a chargeback, a one-star review, and a batch recall. Multiply that by 160 units per minute, eight hours a day. The math is brutal—and entirely preventable.
The CW220 inline check weigher removes the human variable. Products cross a 400 mm load cell at up to 160 pieces per minute; a high-speed AD sampling controller resolves weight to 0.1 g increments and flags any unit outside ±0.3 g in real time. Conformers continue down the belt. Underweight, overweight, or missing-component units are diverted by pusher, air-blow, or flap—without stopping the line. One machine. Zero blind spots. Full traceability.
What Accuracy and Throughput Does the CW220 Deliver?
The CW220 resolves weight in 0.1 g increments. Across its 0–1 000 g range, repeatability holds at ±0.3 g for items under 200 g and ±1 g at the upper limit—verified over 10 000-cycle endurance tests at 25 °C ambient.
Throughput peaks at 160 pieces per minute. Belt speed adjusts from 30 to 100 m/min via the touchscreen controller, so you match the CW220 to your upstream filler or wrapper without a bottleneck. In a 2025 field trial at a snack-packaging plant running 14-hour shifts, the unit sustained 152 ppm average output with a 0.04 % false-reject rate over 30 consecutive days.
What this means for your line: every gram you overfill costs you margin; every gram you underfill risks a regulatory fine. The CW220 keeps you inside the legal tolerance window on 100 % of units—not a statistical sample.
Which Industries and Package Types Can It Handle?
The CW220 is engineered for small-format products: sachets, blister packs, vials, pouches, and component kits up to 280 mm (L) × 200 mm (W) × 1 000 g.

Dose accuracy
The controller stores 99 product recipes. Switching from a 5 g earbud pouch to a 950 g nut can takes one touchscreen tap—no mechanical re-adjustment, no line stop. In multi-SKU contract-packaging facilities, this cuts changeover time from 25 minutes (manual scale method) to under 40 seconds.
How Is the CW220 Built for Washdown and Corrosive Environments?
The frame, belt supports, and rejector housing are fabricated from SUS304 stainless steel (18/8 chromium-nickel). Surface finish is 2B mill, Ra ≤ 0.8 µm—smooth enough to resist bacterial adhesion and withstand daily alkaline foam cleaning at pH 12.
Operating envelope: 0 °C to 40 °C ambient, 30 %–95 % RH non-condensing. In a 12-month deployment at a coastal seafood-processing plant (average 85 % RH, weekly chlorine wash), zero corrosion pitting was recorded on the frame, and load-cell drift stayed within ±0.05 g.
Rated power draw is 0.3 kW at AC 220 V ± 10 %, 50/60 Hz. No three-phase supply needed—plug into any standard single-phase outlet.
What Rejection Options Are Available, and How Do They Protect Product Integrity?
Standard configuration ships with a pneumatic pusher (requires 0.6–1.0 MPa compressed air, Φ8 mm fitting). Three alternatives are available at order:
Air-blow nozzle – for ultra-light sachets (< 10 g) where mechanical contact would tear the seal.
Flap diverter – for rigid cartons and bottles; gravity-assisted, zero air consumption.
Belt-stop + manual pick – for high-value electronics where any impact is unacceptable.
Rejection actuation time: 80 ms from weight signal to pusher full stroke. In a missing-screw detection test (M3 × 8 mm screw, 1.2 g), the CW220 identified 997 of 1 000 seeded defects at 120 ppm line speed—a 99.7 % catch rate with zero false accepts.

Frequently Asked Questions
Q1: What is the maximum weighing capacity of the CW220 check weigher?
A: 1 000 g. This covers the majority of small-pack food, pharma, and electronics products. For items above 1 kg, see our CW500 series (5 kg range).
Q2: How accurate is the CW220 in a production environment?
A: ±0.3 g for products under 200 g; ±1 g at the 1 000 g ceiling. Resolution is 0.1 g. Accuracy is maintained at full 160 ppm speed, verified over 10 000-cycle endurance testing.
Q3: Can the CW220 keep up with a high-speed packaging line?
A: Yes. Maximum throughput is 160 pieces per minute with belt speed adjustable from 30 to 100 m/min. It synchronizes with upstream fillers and downstream cartoners via dry-contact or Modbus signal.
Q4: Is the CW220 suitable for wet or washdown food-processing areas?
A: Yes. The frame is SUS304 stainless steel (Ra ≤ 0.8 µm). It operates at 0–40 °C and up to 95 % RH, and tolerates daily alkaline or chlorine-based foam cleaning without corrosion.
Q5: What rejection method should I choose?
A: Pusher (standard) suits most rigid packs. Choose air-blow for sealed sachets under 10 g, flap diverter for bottles and cartons, or belt-stop for fragile electronics. All options use the same 80 ms actuation timing.
