Description
Ron 2501 – Wireless Dynamometer for Precise, Long-Range Load Monitoring
The Ron 2501 is an ultra-compact, lightweight wireless dynamometer, engineered for high-precision load monitoring in industrial environments. With an exceptionally long transmission range and a built-in signal verification mechanism, the Ron 2501 ensures unmatched reliability in every measurement.
Its unique perpendicular design eliminates load cell bending, enhancing measurement accuracy and operator safety—critical features in demanding lifting and rigging applications.
Equipped with fatigue-rated load cells and an accuracy of ±0.1% full scale, this low-headroom dynamometer is ideal for environments where space and mobility are essential. Despite its compact size, the Ron 2501 delivers powerful wireless performance, operating up to 2,000 hours—or up to 4,000 hours with an extended battery pack—on standard AA disposable batteries.
The Ron 2501 can also be integrated into a multi-point wireless system, supporting up to 200 load cells simultaneously—a perfect solution for complex load monitoring in construction, heavy lifting, and aerospace sectors.
Built from high-grade aerospace steel and protected by shock-absorbing electronic housings, the Ron 2501 is designed for harsh industrial environments, offering rugged durability and long-term performance.
Optional features include remote displays, real-time data logging, and measurement export capabilities, making the Ron 2501 a smart choice for operations that demand precision, scalability, and efficiency.
With over 49 years of innovation, Eilon Engineering remains a global leader in wireless load monitoring systems, trusted by industries worldwide for accuracy, reliability, and engineering excellence.

Frequently Asked Questions
The most noticeable difference between a dynamometer and a crane scale would be the presence of a shackle at the top and bottom of a dynamometer while a crane scale features a hook on the bottom.
Crane scales are more suitable for vertical load and weight measurement and dynamometers can be used to measure load and tension in any direction. Due to their low weight and compact dimensions dynamometers are more portable and therefore more suitable for on-site/field work.
Dynamometers can be ordered with an optional carrying case.
Any time a load is lifted, the potential for overload exists. Accurate measurement is paramount in the prevention of dangerous overloads. Even when it is assumed that load parameters are known, dangerous overloads can still occur. Here are a few scenarios:
■ Attempting to lift equipment which has not been freed from its anchor points
■ Miscommunication between personnel responsible for lifting
■ Addition of equipment after the load has been calculated and approved
■ Off-center loading
■ Uneven load distribution when using multiple lifting points, can potentially cause
accidental overload, Even if the lifted item’s weight does not exceed the total load
limitation.
In addition to safety, load monitoring can both increase efficiency and reduce costs:
■ Precise weighing of incoming raw materials and outgoing shipments provides
important data for inventory control
■ Streamlining of manufacturing processes: every time a lift is performed, weight can be accurately measured
■ Foundries can use load monitoring to carefully control the addition of “small additives”, thereby preventing waste and affording the foundry greater control over the composition of their metal
Ron Crane Scales main advantages are:
■ Lightweight and portable
■ Heavy duty designs with shock-absorbing mechanisms
■ The exclusive use of high grade aerospace steel for load cell bodies
■ Shackle holes offset 90 degrees to reduce bending of the load cell - results in increased safety and accuracy
■ Battery life of up to 2000 hours using common alkaline batteries (optional: up to 4000 hours on the wireless Ron 2501)
■ Compact dimensions ensure minimal loss of headroom
■ Short delivery time - in most cases 48-72 hours
■ Reliable transmissions: Our wireless systems are programmed to ensure that the displayed value is identical to that transmitted
■ Four decades in the market with repeat customers such as NASA, Boeing, GE, Lockheed Martin, as well as numerous other organizations and companies.

The Eilon Classic accuracy rate is +/- 0.1% of full scale.
Eilon Engineering, established 40 years ago, is the company who designs, manufactures and markets all our products. Ron StageMasterTM is the brand name of our innovative, wired/wireless load monitoring & overload prevention system for live events that provides an additional layer of safety for convention and trade show centers, arenas, opera houses and companies, like Cirque du Soleil and events like the MTV Video Music awards. Ron CraneMasterTM is the brand name of our advanced multi-point load monitoring system for complex lifting and advanced logistics in industrial applications. Ron Crane Scales is our brand name for the industrial market for valued customers like NASA, Boeing, GE, Siemens, Lockheed Martin and many, many more.
Unfortunately, as with any successful and leading product in the market, our Eilon Classic load cells have fallen prey to this syndrome, and an inferior copy is being marketed by a different company under a different brand name. So do beware! And for ultimate safety and protection, make sure what you are purchasing is a Ron StageMasterTM, Ron CraneMasterTM or Ron Crane ScalesTM system manufactured by Eilon Engineering.
Eilon Engineering manufactures both. It mostly depends on whether the presence of a cable between the load cell and indicator would hinder day to day operations. Wired systems cannot be used in foundries and other high temperature environments since the risk of damage to the cable is high. Wireless systems are also easier to install and are not limited by the length of a cable. The downside of a wireless system is that, like any system relying on radio transmission, it is susceptible to interference and other transmission issues. In scenarios where the reliability of communication between the load cell and indicator is an absolute must (e.g. activating E-stop upon detection of an overload), wired systems are recommended. Additional wireless displays can be added to any wired system to allow measurements to be read wirelessly.
Eilon Classic load cells are available in any capacity up to 300t.
All Eilon Engineering load cells are made of high quality, aerospace steel.
Yes, all Eilon Engineering load cells are fatigue rated, which means that the lifetime of load cell is not limited to by number of loading/unloading cycles (as long as the safe working load is not exceeded).
