Our products include: Load Cells, Load Pins, Multi-Sensor Displays, Line-Riding Tensiometers, Inclinometers, Anti-Two-Block Switches & Displays, Cable Reels, Wind Speed Sensors & Displays, Slew Sensors, Work Area Definition Software, Rated Capacity Limiters and more.
Our Radio Transmitters Division provides Radio Transmitters, Wireless Gateways, Radio Modems, Radio Multi I/O and OEM Radio Module products for general industrial applications.
LSI was founded in 1998 by 3 individuals who had been involved with the design, manufacturing and distribution of hardwired crane instrumentation. They saw the advantages that radio technology could bring to the crane & lifting industries with the elimination of cables, expensive calibration, high cost for field installations and the frustration involved with long term support of cable based technology.
Today, LSI has 80 employees and averages 30% annual growth. We operate from locations in Houston, TX; Quebec City, Canada; Peterborough, UK; Perth, Australia and Dubai, UAE. In our early years, we came to understand that to achieve success in the crane & lifting Industry, we would need to develop and manufacture our own radio chip technology. We have created products that are flexible, versatile and will improve your efficiency, productivity and level of safety on the job site.
A number of crane boom designs are a complex structure for wireless technology to work effectively in proximity to. LSI has mastered its technical capability, operating successfully on cranes and lifting equipment worldwide.
In 2006, LSI released the GS Series Radio Technology. It features a market leading range of 4,000 ft /1,300 m and Direct Sequence Spread-Spectrum Two-Way Communication. We offer two options for powering our transmitters: Operating from 1 D-cell lithium battery (providing up to 2 years of battery life) or from a hardwired permanent power source. Our products operate in environments where RFI is high and other competitors have been unable to provide successful solutions. We can offer explosion proof options for our transmitters with certifications that include CSA-US and ATEX.
From the success that we have had in the crane & lifting Industry, our products have migrated to applications in the general Industrial market place. In January 2010, LSI launched its Radio Transmitters Division to provide general industrial applications with our market proven radio technology.
LSI performs its electrical, mechanical, radio and software development in-house. We are in control of how our technology performs and we know why it works. We are not at the mercy of a third party vendor, which ensures that you are not left high and dry on mission critical applications.
We look forward to assisting you on your next radio technology product application.
