Product Overview

Rapid Solution for Gas Monitoring

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

Choose communication via 4-20mA or RS485 signals as per requirement. Utilize high-reliability solid polymer electrochemical gas detection technology with intelligent algorithm design.

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

This sensor probe is suitable for gas detection in both indoor and outdoor environments, while also monitoring temperature and humidity inside the Stox housing, providing users with real-time dynamic data of the measured environment.

Due to the close correlation between the chemical properties and motion state of gases with temperature and humidity, the performance of sensors is also closely related to the temperature and humidity conditions.

This design provides professional data basis for users to analyze and interpret measurement results. Features RS485 output with temperature and humidity signals.

Intelligent dual assessment of gas sensor performance and lifespan, regularly outputs the lifespan and performance indicators of the sensor regardless of the presence or absence of the measured gas, and promptly issues warning signals.

This feature serves as the data basis for fundamental judgment and analysis in intelligent product design, ensuring product safety and reliability.

Users can obtain information prompts on whether the sensor is operating normally, failing, requiring maintenance, or replacement by outputting signals or RS485 commands.

Each Stox gas sensor detector undergoes professional gas calibration, ready for direct use by the user, with calibration data stored in a flash chip.

For users requiring secondary calibration, calibration can be performed using the calibration software provided by EC Sense via RS485 output, or by directly calibrating the 4-20mA signal.

The Stox series gas sensor detectors utilize standard 4-20mA or RS485 Modbus-RTU industrial signal protocols, making it easier to quickly set up your own monitoring instruments and systems.

Or interface with display instruments, DCS, PLC, and other systems.

Principle of Detection

The intelligent sensor detector is a durable product that converts the original weak current signal of the sensor into a standard 4-20mA or RS485 Modbus-RTU output via digital circuitry.

Solid-state polymer electrochemical sensing technology represents a revolutionary innovation in the field of electrochemical detection. This technology, based on the principle of electrochemical catalytic reactions, detects the electrochemical reaction output signals of different gases.

Accurately measure gas concentration through a sensor with a semaphore. The sensor consists of three catalytic electrodes, solid electrolyte, and gas diffusion holes. Gas reaches the working electrode of the sensor via the diffusion holes.

Electrochemical redox reactions occur on the porous microsurface of the electrode, the solid electrolyte conducts electron transfer, outputs a current signal, and the magnitude of the current signal can represent the gas concentration.
