Who uses the CW 5000 and for what
The Bernardo CW 5000 is an electronic hanging dynamometer designed for weighing suspended loads up to 5,000 kg with an accuracy of 2 kg (approximately 0.04% of full scale). The typical application is in-line suspension with hoists, jib cranes, winches: the instrument is placed between the lifting system and the load to read the actual lifted weight in real time. For weighing heavy industrial components, equipment, medium crates and containers in workshops and industrial warehouses. The large-digit LED display allows weight readings even from a distance during loading operations, a crucial feature for applications in construction sites or warehouses with reduced visibility. Typical battery life is 50-70 hours of actual use. In Krollit customer laboratories, the CW 5000 is chosen by mechanical workshops for checking the weight of lifted parts, logistics warehouses for weighing suspended packages, carpentry workshops for verifying the weight of structures, and construction sites for controlling loads during handling with cranes.
Its place in the Bernardo range
The Bernardo CW hanging dynamometer range consists of 7 models ordered by capacity and accuracy: CW 500 (500 kg, ±0.2 kg), CW 1000 (1,000 kg, ±0.5 kg), CW 2000 (2,000 kg, ±1 kg), CW 3000 (3,000 kg, ±1 kg), CW 5000 (5,000 kg, ±2 kg), CW 10000 (10,000 kg, ±5 kg), CW 15000 (15,000 kg, ±5 kg). Absolute accuracy decreases with increasing capacity, but percentage accuracy remains constant (approximately 0.03-0.05% of full scale).
The CW 5000 model is in the mid-to-high range. For industrial workshops with regular lifts up to 4000 kg. For loads above 5,000 kg, upgrade to the CW 10000 (10,000 kg) or CW 15000 (15,000 kg) from the heavy industrial range.
Difference from the Bernardo ID series: CW dynamometers are electronic FOR WEIGHING; ID hooks are mechanical FOR LIFTING (without weight measurement). For mixed lifting + weighing applications, use a CW; for lifting only, IDs are significantly cheaper.
Krollit Logistics and Support
Bernardo shipping in 5-9 working days (7 days for Southern Italy). With a weight of approx. 21 kg, it is shipped in individual protective packaging and can be easily handled by one person. Chains, ropes, slings, complementary accessories and original Bernardo spare parts are available from stock with 3-5 working days shipping. EN 1677 conformity documentation (for ID hooks) or instrument calibration documentation (for CW dynamometers) is included in the package. Customer support in Italian is available.
Who is the CW 5000 for?
| Profile |
Compatibility |
Reason |
| Passionate hobbyist |
Adequate |
Professional tool; for hobby use it is oversized unless for specific applications involving heavy lifting. |
| Mechanical workshop with part weight control |
Recommended |
Real-time weighing during lifting to verify the actual weight of parts. ±2 kg accuracy suitable for standard workshop loads. |
| Logistics warehouse with hoists/cranes |
Recommended |
For weighing suspended packages before loading/unloading. LED display visible from a distance, 50-70 hours of actual use battery life. |
Not suitable for: applications with loads exceeding 5,000 kg (risk of instrument damage); applications requiring accuracy greater than 2 kg (consider lower capacity models from the same CW series); environments with continuous vibrations (digital reading may fluctuate; the instrument is designed for static weighing); environments with extreme temperatures outside the typical -10/+40°C range for industrial electronic instruments; applications requiring legal metrological certification (initial factory calibration, but not legal certification for commercial weight transactions).

Frequently Asked Questions
What is the difference between the CW 5000 and a bench scale?
The hanging dynamometer weighs suspended loads (suspended from hoists, cranes, winches); the bench scale weighs loads placed on it. These are instruments for completely different applications: the dynamometer is essential where the load cannot be placed (large packages, motors, suspended materials during handling).
The hanging dynamometer is placed between the lifting system and the load: the upper hook attaches to the hoist, the lower hook to the load. The internal load cell measures the tensile force and converts it into weight displayed on the LED screen. For static applications on a platform, a bench/floor scale is the correct choice.
Is the instrument certified for commercial use (weight transactions)?
No, the CW 5000 is an industrial instrument factory calibrated but NOT metrologically certified for commercial use (purchase/sale transactions by weight). For commercial use, MID (Measuring Instruments Directive) certification issued by an accredited body is required.
For internal industrial applications (checking part weight, verifying loads, weighing for internal logistics), factory calibration is sufficient. For commercial applications (selling materials by weight, invoicing based on weight), MID certification with a green 'M' label and official metrological stamp is mandatory: contacts are available from certifying bodies such as INRIM or equivalents.
How long does the battery last in daily use?
Typical battery life is 50-70 hours of actual continuous use. In daily craft use (10-30 minutes per day), the battery lasts 2-4 weeks before requiring recharging.
The integrated rechargeable batteries can be replaced by an authorized Bernardo service center. For intensive continuous use, a mains charger is recommended to be always available in the workshop, or to keep the instrument continuously charging when not in use. The auto-shutdown mode after inactivity significantly extends battery life.
Is the ±2 kg (0.04% of full scale) accuracy really significant?
For standard industrial applications, yes. At a maximum load of 5,000 kg, the relative error is approximately 0.04%. For typical working loads (50-80% of full scale), the relative error is slightly higher but remains below 0.1%.
For controlling the weight of industrial parts (motors, mechanical components, crates), the ±2 kg accuracy is correctly dimensioned. For applications requiring higher absolute precision (e.g., weighing jewelry, high-value unit materials), laboratory dynamometers or precision balances are recommended, not industrial instruments.
How does the periodic calibration procedure work?
For standard industrial use, annual periodic verification with certified standard weights is recommended. The instrument allows correction of the calibration factor through the procedure indicated in the manual.
Periodic verification can be done in the workshop with standard weights of adequate capacity (e.g., 100 kg standard weight for CW 500). For formal annual certification, contact ACCREDIA accredited calibration centers or equivalents. For internal industrial control use, initial factory calibration is sufficient for most application cycles.
