Leine Linde’s new ESR digital strain sensor is now available to monitor structural health on equipment where needed. Offered in North America through Heidenhain Corporation, it is coupled with an encoder using the digital interface EnDat, and offers significantly higher signal quality, accuracy, and robustness when compared with conventional strain gauges.
To use, simply mount the ESR sensor on any flat surface where load or mechanical forces apply to a body. This new product is available for use on cranes, conveyor belts, bridges, wind-turbine rotor blades, or wherever a load or force needs to be monitored on a mechanical structure. Similar to all other products manufactured by Leine Linde, the ESR-sensor is suitable for use in exposed conditions and harsh environments.
The ESR series is a fatigue-free measurement concept providing high-resolution digital input into a system of choice. It is based on an optical encoder attached on a mechanical measuring arm which connects to the body being monitored. The applied force on the structure is calculated by the subsequent system measured as a position difference by the encoder.
The material in the measuring arm of the sensor unit can be adapted to match the material of the measured body. The purpose is to create a passive temperature compensation and further increase the overall measurement accuracy for those installations where ambient temperatures are fluctuating.
Simplicity during installation and commissioning was one of the driving factors during the product development, and therefore different mounting accessories are available. The sensor can be tailored for a permanent installation or used in temporary measurement campaigns.
The sensor resolution is 0.025 µɛ (µm/m) and has a measuring range of ±5 000 µɛ. The product enclosure is IP66-rated, which means it is dust proof and has protection against powerful jets of water. It is of use in a temperature range from -40°C to 100°C.
Leine Linde is based in Sweden with exclusive North American distribution through Heidenhain Corporation in Schaumburg, Illinois. Leine Linde is well known for offering high quality, robust encoders and system electronics for industrial applications. These encoders are renowned for their accurate performance, durability and resistance to external impact in heavy-duty operations and harsh environments. Leine Linde has a global presence in more than 100 markets on every continent.
