AKCP Air Velocity Sensors

The Air Velocity Sensor is designed for use with systems that generate heat and require a steady air flow to dissipate the heat and maintain system reliability and safety.

The sensor is placed in the path of the air stream to monitor the amount of air flow and is connected to a sensorProbe or securityProbe monitoring device. The built-in web interface in these devices can be used to show the air flow information in percentage and graphical displays of the analog data over time. The displays also provide an ON/OFF sensor indication.

In addition to the web interface, the sensor has its an SNMP OID interface for alarm/normal status indication and access to the analog value data. SNMP traps are sent when critical. Polling via SNMP GET is also available.

AKCP Air Velocity Sensor Features

• ON/OFF and % thresholds alarm signal for airflow
• Airflow data graphically displayed of over time
• Accurate and cost-effective flow sensing
• Includes Duct mounting bracket
• Base unit auto detects the presence of the airflow sensor
• Up to 2 airflow sensors per sensorProbe2, 8 per sensorProbe8 and securityProbe devices
• The Air Velocity Transmitter cable length can be extended using a CAT5/6 extension cable, (CABXX) up to 18m

Data Centre Usage Example

In a data centre, the air flow sensor can be used to provide air flow data on the hot aisle return air path from server cabinets venting exhaust air into this area.

With AKCP Air Velocity Sensors installed (using the special mounting brackets) in the return air duct of each cabinet, data for the relative air movement through them can be collected on a sensorProbe and alerts raised if/when the airflow through any cabinet becomes disproportionate to the thermal load in a specific cabinet. This ensures that only the specific amount of air needed to cool the equipment in that server rack is allowed through the cabinet.

Using an AKCP sensorProbe allows additional sensors to be added as the number of server cabinets installed is increased over time.
