Product Overview
Rapid Solution for Gas Monitoring
The Stox by Germany's EC Sense is an intelligent gas sensor detector, simultaneously outputting two-wire 4-20mA and RS485 Modbus-RTU signals.
You can choose to communicate via 4-20mA or RS485 signals based on your needs. Utilizes high-reliability solid polymer electrochemical gas detection technology, with intelligent algorithm design.
Combining gas and temperature/humidity monitoring for industrial safety needs into an integrated design.
This sensor probe is suitable for gas detection in both indoor and outdoor environments, while also monitoring the 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 the sensor is also closely related to the temperature and humidity conditions.
The design provides professional data basis for users' analysis and interpretation of measurement results. Features RS485 output with temperature and humidity signal.
The intelligent gas sensor assesses both performance and lifespan, regularly outputting the lifespan and performance indicators of the sensor regardless of the presence or absence of measured gas, and promptly issuing 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 alerts on whether the sensor is operating normally, failing, requiring maintenance, or replacement by outputting signal 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 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.
Testing Principle
This 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 circuits.
Solid 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 signals of different gases.
Accurately measure gas concentration through a semaphore. The sensor consists of three catalytic electrodes, solid electrolyte, and gas diffusion holes. Gas reaches the working electrodes of the sensor through the diffusion holes.
Electrochemical redox reactions occur at the porous microsurface of the electrode, where the solid electrolyte conducts electron transfer, outputting a current signal. The magnitude of the current signal can represent the gas concentration.
