Product Overview
Rapid Solution for Gas Detection Instrumentation Development and System Integration
The Stox by German EC Sense is an intelligent gas sensor detector, which simultaneously outputs two-wire 4-20mA and RS485 Modbus-RTU signals.
Select 4-20mA or RS485 signal communication as per requirement. High
Reliable solid polymer electrochemical gas detection technology, intelligent algorithm design, and a combined integrated design of gas and humidity/temperature for industrial gas safety monitoring needs.
The 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 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. This design provides professional data basis for users to analyze and interpret the measurement results.
Only RS485 output with temperature and humidity signal.Dual assessment of performance and lifespan for intelligent gas sensors.
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 judgment and analysis in intelligent product design.Data-driven, ensuring product safety and reliability.
Users can obtain information alerts on whether the sensor is operating normally, failed, requiring maintenance, or replacement by accessing output signals or RS485 commands.
Each Stox gas sensor detector is professionally gas-calibrated, ready for direct use by the user, with calibration information stored in the flash chip.
For users in need of secondary calibration, they can utilize the calibration software provided by EC Sense.
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 protocols.
Easier to quickly set up your own monitoring instruments and systems, or integrate with display instruments, DCS, PLC, and other systems.
Principle of Testing
The intelligent gas sensor detector is a durable product, converting the original weak current signal of the sensor,
Digitally converted to standard 4-20mA or RS485 Modbus-RTU output. Solid polymer electrochemical sensor
Technology is an innovation in the field of electrochemical detection, which relies on the principle of electrochemical catalytic reactions to detect the electrochemical reaction output signals of different gases.
Accurately measure gas concentrations through a semaphore. The sensor consists of three catalytic electrodes and a solid-state electrolyte.
Desorption and gas diffusion holes composition. Gas reaches the working electrode of the sensor through the diffusion holes, where electrochemical oxidation-reduction reactions occur on the porous microsurface of the electrode.
Solid-state electrolyte conducts electron transfer, outputs a current signal, with a strong current signal.
Small size can indicate gas concentration.
