With an infrared source and specific filtering on the pyroelectric detectors mounted inside the optical/gas cavity, individual gases or types of gas can be identified and their concentrations determined. These sensors are suitable for reliable monitoring of gas levels in mining applications where the sensor size is restricted and require a flameproof enclosure for the hazardous environment. The IR2xxx Series share the same build and performance standard as the IR1xxx Series, but are labelled as being intrinsically safe for methane monitoring in mining applications. OPERATION APPLICATION To operate, the sensors must be interfaced to a suitable Mining circuit for power supply, output amplification and signal processing. Sensor outputs require linearisation and compensation for ambient temperature variation using FEATURES algorithms in the system firmware. This is necessary for sensors to meet their full performance specification. An For detection of the following gases: embedded temperature sensor facilitates this compensation o Carbon Dioxide (IR21 Series), on certain types. Further compensation for pressure changes o Hydrocarbons (IR22 series, IR23 series) can also be made in an algorithm, provided there is a Gas concentration ranges: suitable input from a pressure sensor. o 0 - 5% Carbon Dioxide (also suitable for 0 to 0.5%v/v) A set of Application Notes is available from the SGX o 0 - 100% Carbon Dioxide Sensortech Ltd website, to explain more about NDIR gas (also suitable for 0 to 10%) sensing and provide advice for the end-user on interfacing o 0 - 100%v/v Hydrocarbons the sensors and processing signals. (also suitable for 0 to 100%LEL) 16.6mm or 19.0mm sensor heights available TECHNICAL SPECIFICATION Embedded temperature sensor in some versions for improved temperature compensation Mechanical Shock-resistant IR Source version available on certain Dimensions See Outlines types Body material Stainless Steel Diffused gas sampling via mesh Approximate Weight 30g Low power Reference channel for self-compensation Special gold plated optical gas cavity for stable signal Environmental levels Ambient temperature range Operational in varying temperature, pressure and for operation: -20C to +60C humidity storage: -20C to +55C Fast response Operational pressure range 30kPa to 130kPa Rugged stainless steel construction Humidity range for operation 0 to 95% RH No moving parts and storage (Non-condensing) Immunity from poisoning Reliable fail-safe operation Certified: ATEX, IECEx Electrical DC supply to detectors 3V to 5V Typical power 180mW 5V IR Source Supply +5V, 60mA (Recommended) (Square Wave at 4Hz, 50% duty cycle) Whilst SGX has taken care to ensure the accuracy of the information contained herein it accepts no responsibility for the consequences of any use thereof and also reserves the right to change the specification of goods without notice.

The Lowest Concentration Range is the lowest range the sensor is suitable. The use of the sensor beyond these ranges will affect the sensors performance. ** All sensors use temperature compensated pyroelectric detectors except for IR2nBD variants which are uncompensated. This refers to a change in the DC voltage output only. Further temperature compensation is required for all sensor variants. HANDLING PRECAUTIONS 1. Do not allow sensors to fall on the floor. This could cause IR Source filament breakage, damage to the pins and the gas entrance aperture. 2. Do not apply mechanical force against the gas entrance aperture. 3. Do not immerse sensors in water or other fluids. 4. Protect the gas entrance aperture against dust ingress and sprayed materials. 5. Anti-static handling precautions must be taken.
