Provide users with real-time dynamic data under the tested environment. Due to the close relationship between the chemical properties and motion state of gases and temperature and humidity.Relevance
Sensor performance is closely related to temperature and humidity conditions, and this design provides professional data for users to analyze and interpret measurement results.
Only RS485 output with temperature and humidity signal.Dual assessment of performance and lifespan for intelligent gas sensors
Regardless of the presence or absence of the gas being measured, the function regularly outputs the lifespan and performance indicators of the sensor and promptly emits warning signals, becoming a fundamental basis for judgment and analysis in the design of intelligent products.
Data-driven, ensuring product safety and reliability.
Users can obtain information alerts on whether the sensor is operating normally, failed, in need of maintenance, or replacement by outputting signal or RS485 commands.
Each Stox gas sensor detector is professionally calibrated for gas, ready for direct use by the user.
Calibration information is stored in the Flash chip. For users requiring a secondary calibration, the calibration software provided by EC Sense can be utilized.
Calibrate the RS485 output or directly calibrate the 4-20mA signal.
The Stox series gas sensor detectors utilize standard 4-20mA or RS485 Modbus-RTU industrial signal modes.
Easier to quickly build your own monitoring instruments and systems, or integrate with display instruments, DCS, PLC, and other systems.
Principle of Detection
This intelligent gas sensor detector is a durable product, converting the original weak current signal of the sensor,
Converted through digital circuitry to standard 4-20mA or RS485 Modbus-RTU output.
Solid-state polymer electrochemical sensing technologyThis technique represents an innovation in the field of electrochemical testing, utilizing the principle of electrochemical catalytic reactions.
Detect electrical reaction output signals of different gases, accurately measuring gas concentrations through signal quantity. The sensor consists of three catalytic electrodes and a solid-state electrolyte.
Quality and gas diffusion holes composition. Gas reaches the working electrode of the sensor through the diffusion holes.
Electrochemical redox reactions occur at the porous microsurface of the electrode, the solid electrolyte conducts electron transfer, outputs a current signal, and the magnitude of the current signal isCan indicate gas concentration.
