Product catalog summary
Overview
Resensys LLC offers the SenSpot™ Strain Gauge, a precision sensing device designed for structural health monitoring across various applications such as bridges, buildings, airplanes, cranes, platforms, and machinery. The device is characterized by its ultra-low power consumption and wireless communication capabilities.
Features & Benefits
  • Longevity: Expected to last a minimum of 10 years without battery replacement.
  • Lightweight: Total weight is approximately 147 grams, with components including a wireless transmitter (120 grams), a 1-foot cable (10 grams), and a strain sensing element (17 grams).
  • Installation: Easy and quick installation within 1-2 minutes. Self-adhesive for steel structures and flange-mount for concrete.
  • Accuracy: Offers a resolution of 1-µStrain and a full range of ±4000 µStrain.
  • Temperature Range: Operates between -40 to +150°F (-40 to +65°C).
  • Communication Range: Effective up to 1.0 km in free space.
  • Size: Compact dimensions for the wireless transmitter (1.96” x 1.96” x 1.34”) and the displacement sensor (4.30”x1.30”x0.35”).
  • Additional Sensing: Capable of measuring temperature, acceleration, and battery voltage.
  • Durability: IP65 rated for weatherproofing, protecting against rain, snow, and UV exposure.
  • Sensing Options: Available in full bridge, half bridge, and rosette strain gauge configurations for both steel and concrete.
Description
The SenSpot™ strain gauge is designed for easy installation and scalability in monitoring structural integrity. It leverages Resensys’s technology for accurate measurement, large-scale sensing, and ultra-energy efficient wireless communication. The device is maintenance-free for over a decade, requiring no calibration or battery replacement post-installation. Its small size and lightweight design allow for easy application to critical structural points.
Wireless Transmitter
The universal wireless transmitter reads analog measurements from the sensing element and transmits digitized data wirelessly to the SeniMax system. It is available in self-adhesive or flange-mount form factors.
Strain Gauge Sensing Element
The strain gauge sensing element outputs an analog signal after receiving an excitation signal from the wireless transmitter. It is self-adhesive and intended for use on steel structures.
