Hot Spot Monitor - Non-Conductive Fiber-Optic technology

Electrically non-conductive optical fiber is ideal for conductive environments as it can be routed around live components without dielectric degradation of the equipment. Due to the inherent insulating properties of the materials used, point-source temperatures are measured optically, using a polymer optical fiber as a conduit for the optical signals which are used for measuring temperature.

Maintenance Hub – Communication with IIoT Smart Devices

A GraceSense™ Predictive Maintenance System’s core value is its ability to provide actionable information that enables quick and confident responses to real-time situations. A minimally configured GraceSense™ Predictive Maintenance System comprises of the following:

  1. At least one GraceSense™ Vibration & Temperature Node or Panel-Mount Node
  2. At least one Node configured as a CloudGate
  3. A data access plan

While each CloudGate can wirelessly communicate to thousands of nodes, with practical asset spacing in an industrial environment most installations have one CloudGate Module per 10-20 GraceSense™ Nodes within a 30 meter radius.

Node Configuration – Options & Capabilities

There are two levels of node configuration – the overall node itself and individual sensing channels within the node. Communication Interface options include IEEE 802.15.4 Radio (Zigbee compliant), WiFi, LTE Cellular, Ethernet, USB, & RS-232/RS-485. The following are available Sensor Interface capabilities:

  • Voltage Based Sensors: Current, Humidity, pressure, flow, etc.
  • Resistive Sensors: Thermistor
  • Vibration: Tri-Axial Accelerometer
  • Other Transducers: Thermocouple, RTD, Strain Gauge, etc.
  • Sensor Input Communication: EIP, I2C, RS485, SPI


The entire GraceSense™ family of products have been developed with your cybersecurity in mind and are locally hosted for additional security. First, GraceSense™ Nodes communicate with each other using an encrypted and proprietary IEEE 802.15.4 protocol, and cannot be addressed from outside of our proprietary local network. Then, our GraceSense™ CloudGates securely transmit local data to our cloud-based Amazon AWS databases for storage. Lastly, system users like you access your data through our secure Microsoft Azure-hosted web application built with SSL for end-to-end encryptions.
