Gas Detection 63
Introducing e2v’s New IR11BR and IR15TT-R
These two new sensors use the proven non- dispersive (NDIR) principle to detect and monitor the presence of carbon dioxide gas up to 100% volume. The IR15TT-R has two active gas channels for simultaneous detection of carbon dioxide and methane (or other hydrocarbons). With an infrared source and specific filtering on the pyroelectric detectors mounted inside the optical/gas cavity, the gas concentration can be determined.
The IR11BR
• Infra-red sensor with extended sensing range of CO2 up to 100% volume
• Certified flame proof housing UL, CSA and ATEX
• 0.5% volume CO2 resolution up to 100% volume
• Long life • Low power • Fast response
The IR15TT-R • 0 to 100% vol. carbon dioxide
• 0 to 100% vol. methane (also suitable for 0 to 5% vol. methane)
• Internal thermistor for temperature monitoring
• Long life • Low power • Fast response

Get your Instrument Design Right First Time
MOS Sensors, your Reliable, Cheaper Sensor Solution Many device manufacturers are switching from expensive gas sensors to the low-cost Metal Oxide
Semiconductor sensors (MOS). e2v offers a wide variety of MOS sensors: CO, Dual VOC, NH3, NO2 and O3. The latest sensor used to detect ozone is the MiCs-2610 device it is a unique sensor ideal for low cost ozone measurement. This unique sensor design
utilises a highly sensitive semiconductor manufactured on an automotive production line for outstanding quality and performance.
e2v’s MOS sensors are easily capable to detect and measure combustible and pollution gasses in parts per billion (PPB) and are suitable for many environmental, automotive and industrial applications worldwide. It is critical that the correct application is understood when using these types of sensors, to ensure the best performance is obtained. To ensure the sensor is optimised for best performance contact one of the e2v support engineers for application advice. To learn more about e2v’s MOS sensors visit

If you want your gas sensor instrument design processes to run smoothly, getting it right first time every time, use e2v’s gas sensor evaluation kits. Simply attach the universal power supply, connect to a PC USB port and plug in your e2v gas sensor. The data logging and control software allows the performance of gas sensors to be assessed and makes it easy to capture performance data. Users can experiment with different settings before designing their own instrument. Three evaluation kits are available in the range, the Mics-EK1 MOS sensor evaluation kit the IR-EK2 IR sensor evaluation kit and introducing e2v’s New ECVQ-EK3 evaluation kit which drives the e2v range of electrochemical and pellistor (including thermal conductivity) gas sensors.
Simply go to
www.e2v.com/gassensors and download the new ECVQ-EK3 datasheet for more information.
