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.
Selectable for 4-20mA or RS485 signal communication. High...Reliable solid polymer electrochemical gas detection technology
Intelligent algorithm design integrates gas and temperature/humidity monitoring for industrial safety needs in a combined, integrated approach.
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. This design provides professional data support for users to analyze and interpret measurement results.
Only RS485 output with temperature and humidity signal.Dual assessment of performance and lifespan for intelligent gas sensors.
The function 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, making it a fundamental basis for judgment and analysis in intelligent product design.
Based on our data, the products offer safety and reliability. Users can obtain information alerts regarding the sensor's operational status, failure, maintenance, and replacement by accessing 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 secondary calibration, they can utilize the calibration software provided by EC Sense.
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 protocols.
Easier to quickly build your own monitoring instruments and systems, or integrate with display instruments, DCS, PLC, and other systems.
Principle of Testing
This intelligent gas sensor detector is a durable product, converting the original weak current signal of the sensor,
Converted through digital circuit to standard 4-20mA or RS485 Modbus-RTU output. Solid polymer electrochemical sensing technique
The technology represents an innovation in the field of electrochemical detection. It relies on the principles of electrochemical catalytic reactions to detect the electrochemical reaction output signals of different gases.
Accurately measure gas concentration through a semaphore. The sensor consists of three catalytic electrodes and a solid-state electrolyte.
The quality 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 microscopic surface of the electrode.
Solid-state electrolyte conducts electron transfer, outputs current signals; the magnitude of the current signal isCan characterize gas concentration.
