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.


Continuously Powered System with Display

Delta-T Alert Pro Sensors are powered operate at 5Vdc from a standard 120Vac USB power adapter or directly from a USB port on a Server rack. The LCD display of the Delta T Alert Pro Sensor displays the equipment temperature, ambient room temperature, relative humidity and one user customizable auxiliary data input.

Color Coded Notification Screen

The screen clearly indicates the humidity ambiance plus auxiliary reading on a built-in LCD.

Optional Auxiliary Sensors

Add one additional auxiliary sensor including thermal couple, ultrasound sensor, or current transformer, or connect to the Delta T Alert Pro Advanced sensor to add an additional ten sensors to your system. The Advanced sensor add-on includes three thermal couples, an ultrasound sensor, and six current transformers to support three phase monitoring of 0-5 amp and 4-20 mA currents

Visible Alarm Notification

The Delta-T Alert Pro sensor’s screen will automatically switch into alarm, flashing red and highlighting the monitored value that triggered the alarm for rapid local response to a potential issue.

Limited Warranty

12 Month Limited Warranty on the Sensor.
