Product Overview

Rapid Solutions for Gas Detection Instrumentation Development and System Integration

The Stox by German EC Sense is an intelligent gas sensor detector, offering dual-line 4-20mA and RS485 Modbus-RTU signals.

Select 4-20mA or RS485 signals for communication as needed.

Utilizing high-reliability solid polymer electrochemical gas detection technology, intelligent algorithm design,

Combining gas and humidity/temperature monitoring into an integrated design to meet the safety monitoring needs of the industrial sector.

The sensor probe is suitable for gas detection in both indoor and outdoor environments, while also monitoring temperature and humidity inside the Stox housing.

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

The performance of the sensor is also closely related to temperature and humidity conditions, providing professional data for users' analysis and interpretation of measurement results.

Only RS485 output with temperature and humidity signal.Dual assessment of intelligent gas sensor performance and lifespan

Regularly output the lifespan and performance indicators of the sensor, regardless of the presence or absence of the measured gas, and promptly emit warning signals.

The feature serves as the fundamental basis for the intelligent design of product judgment and segmentation.Data-driven analysis ensures product safety and reliability.

Users can obtain information alerts on whether the sensor is operating normally, failed, in need of maintenance, or replacement through output signals or RS485 commands.

Each Stox gas sensor detector undergoes professional gas calibration, ready for direct use by the user.

Calibration information is stored in a Flash chip. For users requiring a second calibration, the calibration software provided by EC Sense can be utilized.

Calibrate via 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 Inspection

The intelligent gas sensor detector is a durable product, which converts the original weak current signal of the sensor,

Converted through digital circuit to standard 4-20mA or RS485 Modbus-RTU output. Solid polymer electrochemical sensor technology

This technique is an innovation in the field of electrochemical detection, utilizing the principle of electrochemical catalytic reactions to detect the output signals of electrochemical reactions of different gases.

Accurately measure gas concentration through a sensor with three catalytic electrodes and solid electrolyte.Quality and gas diffusion holes composition.

Gas reaches the working electrode of the sensor through diffusion holes, where electrochemical redox reactions occur on the porous microscopic surface of the electrode.

Solid-state electrolyte conducts electron transfer, outputs a current signal; the magnitude of the current signal isCan characterize gas concentration.
