NDIR Carbon Dioxide - Infared Sensors
Alphasense contemporary designed miniature CO2 infra-red sensors are self-contained, plug in sensors with integrated optics contained within standard sized miniature (20.0 mm) gas sensor housings. There are no moving parts within the sensors. An internal temperature sensor is included to enable the temperature to be monitored at the detectors, thereby providing the best means of compensating for temperature effects, including ideal gas law corrections.
CO2 Gas Ranges
IR-CO2-A1 Carbon Dioxide 0 to 5,000-ppm
IR-CO2-A1 Carbon Dioxide 0 to 5% Volume
IR-CO2-A1 Carbon Dioxide 0 to 20% Volume
IR-CO2-A1 Carbon Dioxide 0 to 100% Volume

The LED based CO2 NDIR sensor is a fast response, low power NDIR CO2 sensor. It uses patented Indium Antimonide technology to produce a solid state source/detector pair. This gives a fast response to changes in gas concentration, and high immunity to ambient light/heat sources.
Carbon Dioxide (CO2) is measured by recording changes in the transmission of mid IR wavelengths around the carbon dioxide absorption peak at 4.26um.
The C20 is fully solid state, using an advanced mid IR LED and photodiode pair.
This eliminates the need for heated filaments entirely.
This sensor produces a temperature compensated, linearised output via a serial line, and is extremely simple to integrate into microcontroller based instruments.

General description
di-soric infrared distance sensors OAA... are characterised by a large operating distance, while having a very good colour independence.Thanks to the large diameter of light spot uneven surfaces of stones, sintered material or rough boards will be safely detected. Due to that di-soric infrared distance sensors OAA... are especially suitable for height control in concrete and gravel works, brickyards as well as saw mills. Two independently from each other adjustable thresholds enable diverse operation possibilities.

The detection area of the OP-08C consists of 10 independent areas. By rotating a spherical lens, the size of the area can be easily adjusted between standard size and large size.
As the sensor is very small, it can be aesthetically fitted into the entrance surround. It can be embedded into a transom or ceiling up to 4m.
Use of proprietary sensors and microcontrollers reduce faulty movement due to rain, snow or insects.

• Increased sensitivity for critical applications
The GD10PE is designed for critical applications involving large volumes of air with high velocity. The kind of applications that require reliable detection of low gas concentrations and a fast response.
Typical critical applications include the monitoring of air intakes for HVAC systems in living quarters or generators, and monitoring for potential gas leakages in areas with high temperatures in gas turbine packages.
The GD10PE is a stable instrument, and with a measuring range of 0 – 20%LEL the sensitivity for the GD10PE is 5 times higher than standard point detectors. GD10PE is designed for installation in air ducts and for mounting through walls and bulkheads in places such as pump rooms.
• Based on SimSource™ IR-source
The patented, silicon-based SimSource™ IR-source has a number of unique features and is insensitive to shock and vibration.
Its long-term performance is stable. SimSource™ has an expected in-service life of 60 years exceeding all current competing technologies, which often have an expected in-service life of only 2 to 4 years. SimSource™ comes with an uncompromising 15 years warranty. SimSource™ does not need to be replaced during its service life.

The Model IR400 Infrared Point Detector is a hydrocarbon gas detector that continuously monitors combustible gases and vapors within the lower explosive limit (LEL) and provides alarm indication.
All electronics are contained within an explosion-proof housing so that the IR400's detector information can be processed locally. The IR400 operates with a 4-20mA signal, which is proportional to 0 to 100% LEL gas concentration at the detector. Configurations with analog output, Modbus and HART are available. Modbus and HART data can be used for predictive maintenance.

With the GD10P, the company has succeeded in establishing an international industry standard for gas detection.
The GD10P has been designed to be interchangeable with catalytic detectors using the existing cabling and a separate bridge interface.
Advantages of GD 10P
• No recalibration during its service life,
• 15 years warranty for IR source,
• 5 years full warranty,
• SimSource™ has an expected in-service life of 65 years,
• Very short response time , T90 < 5 secs,
• No false gas alarms.
The easy installation and operation of the GD10P contribute to its all-round solid economy.
The GD10P does not have any internal functions that require regular monitoring or maintenance.

The Tocsin 102 series of gas detectors are designed for cost effective hazardous area gas detection solutions. They incorporate micro processor technology to give a stable 4-20mA process signal output or digital addressable output. The addressable output option allows detectors to be networked on a single cable run giving dramatic reduction in installation costs. Combine with the Tocsin 903 controller for local display and calibration. The in built processor can be used to pre-calibrate the sensor prior to installation. Alternatively calibration can be achieved on site via the Oliver IGD control panel or locally using a handheld PC device or laptop. A range of sensing technologies can be incorporated into the housing to provide the most appropriate detection method.
Available sensor types include
Infra Red
Electrochemical Devices
Gas Detected Include
Flammable Gases
Carbon Dioxide
Carbon Monoxide

The LumaSense Photoacoustic Field Gas-Monitor Innova - 1412 is a highly accurate, reliable and stable quantitative gas monitor. Its measurement principle is based on the photoacoustic infra-red detection method. This means that the 1412 can measure almost any gas that absorbs infra-red light.
Appropriate optical filters (up to 5 + water vapor) are installed in the 1412's filter carousel so that it can selectively measure the concentration of up to 5 component gases and water vapor in any air sample. Further, the instrument can compensate for interference between the measured gases, using the unique Cross-compensation feature. The 1412's detection limit is gas-dependent but typically in the 10-² ppm region.
