The Red Line XDI sensor uses proven non-dispersive single beam dual-wave length infrared principles to detect and monitor the presence of gases. This non-poisoning sensing technique relies on the target gas having a unique well-defined absorption signature. This is used to identify the presence of the target gas and is highly specific. Using a suitable infrared source, an analysis of the optical absorption through the gas allows the concentration of the target gas to be determined.

All sensor driving is internal to the transmitter and full fault monitoring of the sensor and transmitter is continuous. The sensor signal is used to provide a linear output in voltage and 4-20mA format, calibration is by means of 4 and 20mA span potentiometers with the signal being internally linearised without the need for user adjustments.

Rugged and reliable
Explosion proof
Automatic diagnostic system surveillance
Harsh environmental use
Engineered for ease of maintenance and reduced running costs

International Orders

We accept orders from international customers as long as you are using either Visa or Mastercard as your payment method. We have two shipping options for International customers:

Standard Airmail Standard Airmail items will be delivered by your local postal service and should take between 3-7 days to reach the customer depending on the country where the order is being delivered. Standard Airmail does not provide a tracking number and is not insure for loss or damage. We cannot be held responsible for any International orders that go missing using standard Airmail.

We will not be held resonsible for any International orders that go missing in transit. There is always an added risk when sending items overseas. Unfortunately we cannot offer an insured service for International orders at present.
