Series-5 *New Range of instrumentation


Oxygen & Carbon Dioxide High Resolution



The AIR-5 combined oxygen and carbon dioxide analyser is designed for monitoring compressors and other equipment. The analyser is supplied as two components: a touch screen display module (either panel mount or surface mount) and a sensor pack. The analyser uses a fluorescence quenching oxygen sensor, which is accurate and low maintenance, and a long path infrared LED based carbon dioxide sensor that has a 1ppm resolution and long maintenance free life.

The display module has a colour touch screen which is the operator interface. All adjustments, configuration and user interaction is carried out through this graphical interface. High and low alarms can be set for oxygen, high and higher alarms can be set for carbon dioxide. There is also an onscreen graphic flow meter with flow failure alarm. The sensor pack includes a sample flow controller and an electronic flow meter.

The sensor pack is IP 66 rated and can be located close to the equipment being monitored to minimise sample delay.

The display module connects to the sensor pack using a 2 twisted pair overall screened cable. This cable is terminated in either a D-9 connector at the panel mount display module, or an IP67 connector at the surface mount display and through a watertight gland into the sensor pack. The cable length can be several hundred metres long providing good quality cable is used and
correctly installed.

The instrument has a built in black box recorder that logs the readings and alarm status every second in non-volatile memory. The built in storage is capable of recording a year’s continuous data, and if required, a larger data storage capacity can easily be installed. There is an isolated RS485 data output for connection to a data monitoring system such as the SAT Systems CDRS and a logic output to operate a shutdown relay if required.

The unit is powered from a 10-36 VDC power source. All the components are designed for use in a marine environment and the electronics meet the current European standards for electrical safety, electromagnetic emissions and immunity in a heavy industrial environment.
