Zephyr AQS™

Zephyr AQS™ is an ultra-compact, low cost environmental air quality monitoring station for underground mines. This Industrial Internet of Things (IIoT) device connects directly to any network without the requirement of adding an expensive and complex programmable logic controller (PLC).

The Zephyr AQS™ air quality station features three fully customer configurable plug and play sensor inputs that can be freely mixed and matched according to the underground requirements. Configuration is done through built-in webpages similar to that of a home network router. All sensors that connect to the Zephyr AQS™ utilize industry standard digital protocols.

The Zephyr AQS™ fully supports both of the two most popular network communication protocols – Modbus TCP/IP and EtherNet/IP™. Alternately, the Zephyr AQS™ offers optional on-board analog outputs (3 x 4-20 mA) and/or two relay outputs that can tie into any legacy system.

Measurement, full system diagnostic functions, unmatched flexibility and simplicity puts you in the driver’s seat!
