Delta T Engineering's Delta T Alert temperature-monitoring device attaches magnetically to electrical enclosures
The Delta T Alert is a self-contained, temperature-monitoring device that attaches magnetically to electrical enclosure covers, revealing differences between the temperature inside the electrical enclosure and the ambient temperature in the room containing the enclosure.
The Delta T Alert collects temperature data and sends it, via wireless communication, to a desktop or other computer, allowing a building manager or engineer to monitor numerous points of the electrical system from a single online location. Readouts and reports can be generated daily.
To install, drill a 15/32-inch hole in the cover of an electrical enclosure. The Delta T then attaches magnetically to the cover. The hole allows the device’s interior sensor, 7/8 inch long, to penetrate the enclosure to measure internal temperatures. (Both the size of the hole and the length of the interior sensor conform to protection classification NEMA IP20, which prevents hand or finger access to hazardous internal parts.) The rest of the Delta T device, a rectangular unit that includes LED lights and an additional sensor, remains outside the enclosure to measure ambient room temperature. When the internal and external temperatures differ significantly, a signal is sent via wireless communication to a desktop, laptop or other computer. An “Elevated Alarm” signal indicates that close watching, and appropriate alterations in the system, may be needed. If a “Critical Alarm” signal appears, the building engineer knows that immediate attention is required.
