Hydrogen Sulfide (H2S) Sensor: iH2S Operating Principle : electrochemical Size : 20 mm (l) x 20 mm (L) x 10,3 mm (H) Range : 0 ppm to 200 ppm Accuracy : ±5 % of measuring value
Digital interface
The sensor has a UART protocol to communicate with the instrument with chip select option as described in 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.
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.
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.
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 open circuit sensing/high impedance electrode, drift/fault in reference electrode, electrolyte concentration out of range, counter electrode fault; therefore notifying the user to take corrective actions.
