The INIR is a user friendly digital Gas Sensor, which is designed to use the latest SGX Sensortechs Infrared Integrated IR FEATURES technology. The sensor is designed to decrease the implementation time therefore increase productivity. The Integrated IR sensor incorporates the necessary electronics and embedded Gas Sensor with Automatic Switchover between ranges, software to operate from a low voltage DC power supply. The High Resolution up to 20ppm, sensor will process the raw signals to output a linear, Detectivity Level at 100ppm, temperature compensated signal proportional to the gas Multi-sensor mode, concentration applied. The output signal is available in digital Analog Output of gas concentration, and analogue forms. Serial port communication, The SGX Sensortech Integrated IR Gas Sensor provides Internal Temperature sensor users with a simple method of incorporating an Infrared Active & Reference Signals Monitored Sensor into their gas detection instrument which will Full Faults Diagnostics & Error Generation significantly reduce the development time and expertise Cyclic Redundancy Check (CRC) required during the design and implementation phase. The Typical Low power consumption < 100mW (Average) Integrated IR can also be factory calibrated to allow Factory calibrated for Propane or Carbon Dioxide installation without the need for recalibration. Evaluation Kit available including PC software for easy testing and production calibration functions RECOMMENDED APPLICATIONS Easy implementation into Sensors Network Design for use in Hazardous Areas Automation & Control Certified Sensor for use in Explosive Atmospheres (EX) Indoor Air Quality Industrial Health & Safety Whilst SGX Europe Sp. z o.o. 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.
