Product Overview

Rapid Solutions for Gas Detection Instrumentation Development and System Integration

The Stox by Germany's EC Sense is an intelligent gas sensor detector, which simultaneously outputs two-wire 4-20mA and RS485 Modbus-RTU signals.

Available for communication via either 4-20mA or RS485 signals, as per requirement. High...Reliable solid polymer electrochemical gas detection technology

Intelligent algorithm design, integrating gas and temperature/humidity monitoring for industrial safety needs in a combined, integrated system.The sensor detector is suitable for gas detection in both indoor and outdoor environments, while also monitoring the temperature and humidity inside the Stox shell.

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; this design provides professional data for users to analyze and interpret measurement results.

Only RS485 output with temperature and humidity signalDual assessment of the performance and lifespan of intelligent gas sensors

The function, which regularly outputs the lifespan and performance indicators of the sensor regardless of the presence or absence of the measured gas, and promptly emits warning signals, forms the foundation for the judgment and analysis of intelligent product design.

Based on our data, ensuring product safety and reliability.

Users can obtain information alerts on whether the sensor is operating normally, failing, requiring 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 the Flash chip. For users who require 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 connect to display instruments, DCS, PLC, and other systems.

Principle of Detection

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

Converted through digital circuit to standard 4-20mA or RS485 Modbus-RTU output. Solid-state polymer electrochemical sensing technique

This is an innovation in the field of electrochemical testing, relying on the principle of electrochemical catalytic reactions.

Measure gas concentrations accurately by detecting electrochemical reaction output signals of different gases.

Sensor consists of three catalytic electrodes and a solid-state electrolyteQuality and gas diffusion pore composition.

Gas reaches the working electrode of the sensor through diffusing holes, where electrochemical oxidation-reduction reactions occur on the porous microscopic surface of the electrode.

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