Protos Wireless Load Cell Receiver Dongle (500m Range)

Wireless base station mounted in a non-weatherproof USB dongle enclosure for direct connection to laptops and tablets.

When you prefer to monitor the forces on a PC, the receiving base station is the connection between the wireless signals from the transmitting Protos devices, like load cells and windspeed meters, and your computer.

The PROTOS USB base stations follow the simplicity of the entire system. When all transmitting units in your stock are set to the same radio channel it’s plug and play. The receiver will automatically recognize the radio channel as used and will find the transmitter units within range.

Base stations are the interface between the PROTOS radio system and a PC, PLC or other controller. A base station would be required to configure PROTOS transmitter modules from a PC using the Protos Toolkit software and also required if you are to capture data from PROTOS transmitter modules to a PC or PLC.

The entertainment industry is developing at a fast rate in order to keep up with the latest developments. As the hunger for state of the art shows keeps growing, concerts, plays and shows are constantly evolving as each itteration has to be more specatular than the last. As a result rigging has taken a prominent role in almost every show.

Rigging plots have become more complex due to performers, props, construction and the like being utilised as premium parts of the show. In this landscape, being able to measure the load that you’re lifting is essential for safe working conditions, to protect people and priceless equipment.

For this, we have developed a comprehensive range of force monitoring equipment for the entertainment industry. A complete line of wireless and wired daisy chain loadcell shackles ranging from 3.25 to 4.75 Tonnes is available for in and outdoor use thanks to the use of IP67 rated enclosures.

The shackles are equipped with a unique centralising bobbin for precise measuring of the load. The daisy chain loadcells can be run with up to a 1000 meters of wire and can be used in groups of up to 32 units. The wireless loadcell receivers have a range of up to 800 meters, this can be further extended by 800 meters when using the PROTOS active repeater. Using the repeater also makes it possible to circumvent signal blocking obstacles.

The force monitoring software can be installed on a computer or tablet with Windows OS installed. Personalised settings, configuration and layout of the soft- and hardware can be easily achieved with their quick start guide.

Also available is the wireless handheld receiver for quick reverence of individual loadcells. The handheld will wake the loadcells up when in range. Other devices PROTOS offers are an integratable wireless wind speed meter, power pack, a solar panel to charge it that can be of great value when having long term setup and many more products.

For users with more specific needs, we have a GPRS transmitter unit available, which is able to send an email or SMS to any phone in the world as soon as a user determined limit, such as for example high wind speeds or loading limits, has been reached. Sudden changes in weather conditions can be very problematic, but with this unit, surprises like an overload when there is no rigger present on site can be mitigated.

To improve safety, with a focus on the flexibility and ease of use that this industry needs. Making an intuitive and affordable solution to measuring the forces on the loads you’re lifting, or the structures you’re building!
