Description
SenSpot sensors provide a low cost, easy to install,
scalable solution for distributed structural integrity
monitoring. Strain gauge sensor is one of the family
members of the Resensys SenSpot™ Technology.
Like other sensors in this family the unit is based on
Active RF Technology (ART), which offers a high
performance method for large-scale sensing,
wireless synchronization, and ultra-low-power
wireless communication. With ultra-low-power
sensing and wireless communication technology

SenSpots are meant to operate maintenance-free
for decades. This device is powered using a built-in
prime lithium-ion battery which is designed to
supply the energy needed for the device upto 30
years. After installation, the devices do not need
any calibration, battery replacement, or other
maintenance during their entire service life. Due to
small size and lightweight, adhesive-mount SenSpot
sensors can be applied easily to as many critical
spots on structures as needed, with minimal installation effort.
Attachment of SenSpots does not require drilling or
any complicated mounting procedure. The average
installation time for a strain gauge sensor is 3-5
minutes. As a part of the Resensys solution for
integrity monitoring system strain gauge sensor can
be used for measurement of strain on infrastructures. Such structures include but are not limited to
bridges, building, etc. In addition, the sensor monitors changes in these parameters as the structure
expands or contracts as a result of temperature
variations. Any abnormality in the structure behavior is tracked and reported to the user using
SenScope. Strain Gauge sensor uses cold cured
adhesives for attachment to the structure. Refer to
the installation manual to find the Resensys recommendation.
