MSI

MSI 7300 series digital dynamometers are specified at ±0.1% of full scale accuracy. This applies across the capacity range from 1,000 lb to 100,000 lb. Readability varies by model: for example, the 1,000 lb unit has 0.5 lb readability, the 25,000 lb unit has 10 lb readability, and the 100,000 lb unit has 50 lb readability. The accuracy figure is a key parameter for users who need to verify that the instrument meets the tolerances required for their lifting or tension measurement application. It is important to note that accuracy is expressed as a percentage of full scale, not of the reading, so the absolute error at low loads will be smaller than at high loads.

Several MSI 7300 series models include an RF receiver for use with the MSI-8000 remote display. From the available SKUs, these include the 2,500 lb (MSI-7300-2500RF), 25,000 lb (MSI-7300-25000RF), and 50,000 lb (MSI-7300-50000RF) capacity units. The RF receiver allows the dynamometer to transmit weight data wirelessly to the MSI-8000, which can be mounted in a crane cab, control room, or other remote location. This is useful when the lift point is not easily visible or when the operator needs to monitor the load without being directly under the suspended load. Models without the RF receiver are also available and may include a user guide or safety documents instead.

MSI crane dynamometers in the 7300 series are indicated as complying with specific standards depending on the model. Some SKUs reference OSHA 29CFR1910 Subpart N, which covers materials handling and storage, including overhead and gantry cranes. Others reference OSHA 29CFR1910.179, which is the standard for overhead and gantry cranes. Several models also comply with ASME B30.26-6, which addresses below-the-hook lifting devices. These standards are relevant to users who must ensure that their lifting equipment meets regulatory requirements for safety and performance. The specific compliance for each SKU is listed in the product specifications, and 3G Electric can provide the relevant documentation with the product.

The MSI 7300 series dynamometers available from 3G Electric cover capacities from 1,000 lb to 100,000 lb. Specific models include 1,000 lb, 2,500 lb, 5,000 lb, 10,000 lb, 25,000 lb, 50,000 lb, and 100,000 lb. Readability scales with capacity: 0.5 lb for 1,000 lb models, 1 lb for 2,500 lb, 2 lb for 5,000 lb, 5 lb for 10,000 lb, 10 lb for 25,000 lb, 20 lb for 50,000 lb, and 50 lb for 100,000 lb. All units in this series are digital, use a steel housing, and offer ±0.1% accuracy. Weighing units may be in pounds or kilograms depending on the model. This range allows users to select a dynamometer that matches the expected load with appropriate resolution.

The MSI-8000 remote display is a separate readout unit that receives weight data wirelessly from compatible MSI dynamometers equipped with an RF receiver. The dynamometer transmits the weight reading to the MSI-8000, which displays it on a large-digit screen. This allows the operator to monitor the load from a distance, such as from inside a crane cab or from a safe location on the ground. The RF receiver is built into specific dynamometer models, typically indicated by an 'RF' suffix in the part number, such as MSI-7300-25000RF. The MSI-8000 is not included with the dynamometer unless specified; it is a separate accessory. Users should verify compatibility and range requirements for their specific site conditions.

Depending on the specific SKU, MSI dynamometers from 3G Electric may include safety documents, a user guide, or both. For example, the 5,000 lb and 100,000 lb models include safety documents, while the 1,000 lb and 10,000 lb models include a user guide. Some models with RF receivers may include the receiver but not necessarily the full documentation set. 3G Electric can provide datasheets and additional documentation upon request. It is recommended that users retain all safety and compliance documentation for their records and for any required inspections or audits. The exact inclusions are listed in the product specifications for each SKU.
