Overview
The BOSEAN K-G60 (EX) is a stationary Gas detector for continuous monitoring of combustible gas (EX) concentrations. Supporting several Sensor types and Installation methods, the product features standard signal output and optional wireless transmission for fixed point gas monitoring in industrial environments.
Features
1. Supports a variety of Sensor types, including electrochemistry, catalytic combustion, semiconductor, PID light ion and infrared gas Sensors, which can be flexibly selected according to the detection gas.
2. Provide Wall-Mounted, Pipeline, Circulation, Pump Suction and other Installation methods to adapt to different site installation needs.
3. Standard 4-20mA and RS485 (MODBUS RTU protocol) signal output, and optional 433MHz wireless transmission function, easy System integration and remote monitoring.
High Protection Rating (IP65) and explosion-proof certification (Exd II T6 GB, CNEx16.0449) for harsh and hazardous industrial environments.
5. Provide two sets of relay outputs, which can be used to connect external devices such as sound and light alarms.
Principle
The detector senses the concentration of a specific gas in the environment through a built-in gas Sensor (such as the catalytic combustion Sensor for detecting combustible gases). The Sensor converts the gas concentration signal into an electrical signal. After internal circuit processing, amplification and linearization, it outputs the standard MODBUS RTU protocol data with 4-20mA analog signal or through the RS485 digital interface for the host computer or Control system to read, to realize real-time monitoring and alarm of gas concentration.
Applications
Petrochemicals, gas transmission and distribution, metallurgical casting, electric power energy, pharmaceutical production, environmental protection monitoring, underground pipe gallery, warehousing and logistics
Standards
Exd II T6 GB、CNEx16.0449
Steps
1. According to the site environment and testing requirements, select the appropriate installation location and method (wall hanging, pipeline, etc.), and ensure that it meets the requirements of the explosion-proof area.
2. Connect the power supply (DC24V +/- 15%), signal output line (such as 4-20mA or RS485) and relay output line correctly according to the wiring diagram. It is recommended to use 3X1.5mm ² Shielding cable, the interface specification is M20x1.5 or G1/2.
3. After power on, the instrument enters the preheating and self-test state. After stabilization, perform zero-point calibrating in clean air (if necessary).
4. Through the supporting host computer software or equipment that supports the MODBUS protocol, configure or read the instrument parameters, such as range and alarm point (the default is to understate 20% LEL and overstate 50% LEL).
5. After the installation is completed, conduct a ventilation test to verify whether the response, alarm function and signal output of the detector are normal.
Notice
• Installation, commissioning and maintenance must be carried out by professionals, and the relevant safety regulations for explosion-proof electrical equipment must be strictly adhered to.
• Ensure that the Ambient Temperature (-20~ 50 ℃) and Humidity (≤ 95% RH, no condensation) are within the allowable range of the instrument.
• Avoid long-term operation of the instrument in an environment beyond the specified pressure range (86~ 106Kpa).
• Regularly calibrate the Sensor to ensure detection accuracy and prevent measurement errors due to factors such as zero drift.
• Relay output contact capacity is limited (30VDC 2A/220VAC 0.3A), do not overload.
• When choosing pump suction installation, pay attention to sample gas treatment to avoid dust, moisture and other damage to the Sensor or affect the test results.
