Developed to help prevent civil disasters and save lives, Heidenhain’s ESR digital strain sensor is available to monitor structural health on bridges and buildings, to provide preventative maintenance information.  With a renewed emphasis on improving the national infrastructure, the digital ESR strain sensor is the perfect option as it offers significantly higher accuracy and increased robustness when compared with conventional strain and vibration gauges.  It also offers transferable mounting allowing users to move the one-gauge sensor to multiple locations.

The ESR series is a fatigue-free measurement concept providing high-resolution digital input into a system of choice. This sensor offers structural engineers and inspectors the ability to detect and analyze acute risk and continual loading on a bridge or building, monitoring strain, and allowing them to make necessary adjustments to avoid potential tragedies.

The ESR strain sensor with a high-quality encoder using the digital interface EnDat providing the higher signal quality than otherwise available.  It is easy to install and is transferable to other locations by simply manipulating the integrated footing system.  It is also suitable for use in exposed conditions and harsh environments. 

The ESR sensor detects strain of down to 0.025 μ? (μm/m) and measure dynamic vibration of up to 30 kHz.  It has a measuring range of ±5000 μ?. The product enclosure is IP66-rated, meaning it's dust proof and has protection against powerful jets of water. It is of use in a temperature range from -40°C to +100°C.
