A customer with a large number of electrical panels on their site was experiencing frequent incidents of fires and short circuits. To mitigate this risk, they needed a reliable way to monitor the temperature inside each panel. A wired solution was impractical and cost-prohibitive due to the sheer number of panels. Therefore, the customer sought a wireless temperature monitoring system that could be integrated into their existing SCADA system for centralized data acquisition and analysis. The key requirements were for a wireless temperature sensor for each panel, with the data transmitted to a gateway that could be accessed over an Ethernet network using the Modbus TCP/IP protocol. The customer also needed the flexibility to adjust the data transmission rate to as fast as once per second to ensure timely alerts in the event of a rapid temperature increase.
The proposed solution was a wireless temperature monitoring system comprising of IWTT series wireless temperature transducers and an IWR-PORT gateway. The IWTT transducers are designed for industrial applications and can be supplied with 3-wire RTD sensors, which were ideal for this application. These sensors are housed in a rugged acetal enclosure, making them suitable for the industrial environment of the electrical panels. The IWTT transmitters are powered by a long-life lithium battery, with a lifespan of up to five years at a 10-second transmission rate, which simplifies maintenance and reduces the total cost of ownership. A key advantage of the IWTT is its user-selectable transmission update rate, which can be configured to be as fast as one second, meeting the customer’s requirement for rapid data updates.
The data from the IWTT transmitters is wirelessly sent to the IWR-PORT gateway. This gateway acts as a central receiver and network coordinator, capable of handling data from up to 128 wireless sensors. The IWR-PORT is equipped with an Ethernet port and supports the Modbus TCP/IP protocol as a standard feature, allowing for seamless integration with the customer’s SCADA system. This enables the customer to monitor the temperature of all electrical panels from a central location, receive timely alerts, and analyze historical data to identify trends and prevent future incidents. The IWR-PORT also features a local display for on-site monitoring and configuration. The combination of the IWTT wireless temperature transducers and the IWR-PORT gateway provides a scalable, cost-effective, and easy-to-install solution for monitoring the temperature of electrical panels, enhancing safety and operational efficiency.
