iH2S GAS SENSOR 002706 Issue 5 Hydrogen Sulfide (H2S) Intelligent Series Gas Sensor (iseries) DOCUMENT PURPOSE The purpose of this document is to present the performance specification of the intelligent iH2S hydrogen sulfide gas sensor. This document should be used in conjunction with the Product Safety Datasheet (PSDS 5). For guidance on the safe use of the sensor, please refer to the Communication Protocol (SDCS) and Sensor Mounting Application Note. PORTFOLIO Compact, digital and intelligent gas sensors, iseries sensors are precalibrated, interchangeable and feature digital traceability. These sensors are rated for longer life and are designed to operate in extreme environmental conditions. 2 YEAR WARRANTY (24 months from date of despatch) Hydrogen Sulfide (H2S) Sensor: iH2S Part Number: AC400-R00D-CIT FEATURES AND BENEFITS UART Digital interface – The sensor has a UART protocol to communicate with the instrument with chip select option as described in the Communication Protocol (SDCS) Interchangeable – All intelligent sensors have the same dimensions and communication protocol. All sensors in the range will work with a supply voltage from 3.1 V to 3.3 V Digital traceability – Sensors contain the following data: serial number, manufacturing date, and gas type for quick and easy identification of the sensor Pre-calibrated – Sensors will be calibrated during manufacturing and calibration data is written in the sensor. Sensor will output gas concentration when interrogated by instrument OEM lock – Sensors have two levels of lock codes. The first one is an OEM specific code programmed in during manufacture and cannot be modified. This lock code is provided by the OEM. Instrument can check if the sensor has the unique code – if not the instrument can refuse the sensor. The second level of lock code is left blank and can be updated by OEM/Partners during sensor integration into the instrument as needed Predictive calibration – Sensors can predict in advance when its accuracy is becoming too poor to give a reliable, accurate reading (advanced warning of when recalibration is needed). End-of-life indication – Sensors can predict in advance when its sensitivity is falling too low to give a reliable, accurate reading (advanced warning for sensor replacement). Fault indication – Intelligent sensors can detect several internal faults like drift/ fault in reference electrode, electrolyte concentration out of range, counter electrode fault; therefore notifying the user to take corrective actions Compact form factor Designed to meet global performance standards Five-year life ATEX and IEC Ex Certified per EN IEC 60079-0 and EN IEC 60079-11 RoHS compliant Designed to meet performance standards: BS EN 45544-1, AS/NZS 4641 and ANSI/ISA 92.00.01 INTELLIGENT SERIES GAS SENSORS (iSERIES) iH2S SERIES Product Dimensions Target Gas H2S Range 0 ppm to 200 ppm Accuracy ±5 % of measuring value T90* Response Time
