LCM Systems Ltd - Wireless Telemetry Load Cells

LCM Systems Ltd was formed in 1984 to specialise specifically in the monitoring of rigging forces in top performance racing yachts. At this time the company teamed up with Diverse Yacht Services in the UK to provide the yachting industry with precision load cells and readout systems throughout the world - marketed under the LoadSense name.

This market still plays a significant part in the product mix of the company and has helped the development of many new products and techniques over the years. The waterproof integrity and reliability of such systems is vital to the discerning yachtsman and LCM are proud to be recognised as the world leaders in this field.

LCM has built up significant expertise in many other sectors of industry where standard (and special) products can be supplied in very reasonable time scales. In February 2004, we acquired the Transducer manufacturing business of Pioden Controls.

LCM Systems manufacture a wide range of standard and custom design load cell products. We have categorised our range to enable our customers to find their product of choice quickly.

The categories we have broken our load cell products into for this web site include:

• Compression Load Cells
• Tension Load Cells
• Tension & Compression Load Cells
• Beam Load Cells
• Load Measuring Shackles
• Load Measuring Pins
• Load Monitoring Links

The PD13 replaces the PD20 range of displacement transducers, as previously manufactured by Pioden Controls (which is now part of LCM Systems).

The PD13 offers many benefits over the PD20, including, low noise, greater resolution and improved availability.

The PD13 covers a wide range of options covering 25mm to 200mm strokes. They are used in many applications, including research laboratories, winding machines, civil engineering and motorsport.

The simple circuit arrangement for this type of sensor makes them ideal for OEM applications as well as lower volume special applications.
