24/7 Continuous Monitoring of Electrical Enclosures

24/7 Continuous Monitoring of Electrical Enclosures

The Delta-T Alert™ wireless systems constantly monitor every critical electrical enclosure in a facility and complements existing electrical maintenance programs. The system also offers energy savings by allowing for the timely repair of loose connections that create increased resistance, thus resulting in higher energy costs due to losses. The cost of cleaning and replacing electrical components is low compared to energy savings realized through preventative maintenance.

An Easy Way to Reduce Risks

Delta-T Alert™ bridges the gap between your routine Condition Based Maintenance inspections and brings your critical assets into a CAST model. The Delta-T System monitors and reports critical temperatures within your electrical enclosures daily and effectively tracks your electrical system enclosure temperatures and sends data for analysis and trending. If a critical issue arises, immediate notification allows for an appropriate corrective action long before costly damage occurs. The system warnings that Delta-T Alert™ provides allow for maintenance technicians to be warned of potential issues causing the elevated internal ambient temperatures. This information and trend data gives maintenance personnel a significant safety advantage prior to any type of routine maintenance or troubleshooting of possible electrical anomalies within the electrical enclosures.

Easy Installation

The Delta-T Alert™ system installation is easy. For permanent installations, simply drill a 9/16” hole in the enclosure and mount the unit tightening the clamp nut provided. If only a temporary installation is required, the Delta-T Alert casing also has a permanent magnet for mounting on ferrous metal enclosures. Each sensor pairing and configuration can be completed in less than 2 minutes. It’s that easy!

Limited Warranty

12 Month Limited Warranty on the Sensor


Battery Operated

Delta-T Sensors operate on three (3) standard “AA” batteries which will last up to 18 months under normal operating conditions. Battery status is communicated wirelessly to the software and battery swap can be performed without the need for an equipment shutdown.

350ft Wireless Connectivity

Each Delta-T sensor communicates wirelessly to the Delta-T Gateway with range of up to 350ft unobstructed. Walls, equipment and other obstructions may reduce the effective range. Up to 230 Delta T sensors can communicate to a single Delta T Gateway and multiple Gateways can be tied together to create your total monitoring system.

Custom Reporting & Scheduling

Set schedules and get reports instantly.

Dual Temperature & Humidity Sensors

Delta-T Sensors communicate the Internal Equipment Air Temperature, the Ambient Air Temperature and the Relative Humidity back through the Delta T Gateway. Data is logged via the Delta T Software and trend plots can be viewed for each Delta T Sensor.

Optional Environmental Housing

For outdoor, dusty or wash-down applications, an optional environmental housing is available for Delta T Sensors.
