Analysis of cabinet thermal properties and airflow
All In One Wireless Cabinet Sensor
The Wireless Cabinet Analysis Sensor (W-CAS) features a cabinet thermal map for detecting hot spots, differential pressure sensor for analysis of airflow and 2x dry contact inputs for door security sensors. Powered by USB, or 4x AA rechargeable batteries and using AKCP Wireless Wall Penetrating Technology data is collected and sent to one of our wireless sensor gateways. A wired version of the W-CAS is also available for use with the sensorProbeX+ base units.
Cabinet thermal maps consist of 2 strings of 3x Temp and 1x Hum sensor. Monitor the temperature at the front and rear of the cabinet, top, middle and bottom. The △T value, front to rear temperature differential is calculated and displayed with animated arrows in AKCPro Server cabinet rack map views.
There should always be a positive pressure at the front of the cabinet, to ensure that air from hot and cold aisles are not mixing. As air travels from areas of high pressure to low pressure, it is imperative for efficient cooling to check that there is a higher pressure at the front of the cabinet and lower pressure at the rear.
I/O dry contact inputs can be used to monitor the front and rear doors of the cabinet, or alternatively alarm outputs from a UPS or other rack mounted equipment.
Rack Maps and Containment Views
The L-DCIM runs AKCPro Server. Dedicated rack maps displaying W-CAS sensor data can be configured to give visual representation of each rack in your data center. If you are running a hot/cold aisle containment, then containment views can also be configured to give a sectional view of your racks and containment aisles.

|Note 1: for 5V pull-up non-isolated, they all share the same ground.
Care should be taken on grounding when connecting the inputs to the dry contacts
Note 2: for 5V pull-up non-isolated, don’t apply any voltage to the dry contact inputs
