Wireless Enhanced Strain Gauge IoT SenSpot™

Description

The Wireless Enhanced Strain Gauge IoT SenSpot™ by Resensys is a stand-alone product and cost-effective solution for distributed structural integrity monitoring. This wireless IoT strain gauge sensor measures data from two separate strain gauges and features an easy installation with either flange or adhesive mounts. Equipped with a high-capacity lithium-ion battery charged by a solar panel, it operates maintenance-free.

Based on the SeniMax™ Lite architecture, IoT SenSpot™ sensors can be applied easily to as many critical spots on a structure as needed with minimal installation effort.

With its robust design and IP68 weatherproof protection, it is ideal for strain monitoring in outdoor and hard-to-reach locations. The strain gauge IoT sensor uses a Nano SIM card with 4G LTE for remote data transmission without needing an intermediate device for sending the data, reducing overall project costs, especially for smaller projects.
