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.
