The GAOPIN NGP5-C6H6-A Stationary Benzene Alarm Instrument is an online benzene Gas detector that uses a Thermal Conductivity Principle Sensor to continuously monitor the benzene gas concentration in the field for 24 hours. The instrument is equipped with a 1.7-inch high definition color screen display real-time concentration, supports excessive sound and light alarms (optional) and remote signal transmission. The rugged explosion-proof housing makes it suitable for various hazardous locations and harsh industrial environments.
1. Units can be switched freely. 2. Diversified communication methods: support wired or wireless remote transmission, network transmission; can simultaneously output three-wire system 4~ 20mA standard signal and standard bus RS485 (modbus-RTU); optional frequency output, Hart protocol, 1~ 5V output, two-wire system 4~ 20mA, SMS alarm, wireless transmission, etc. 3. Standard infrared remote control, support operation without opening the lid in dangerous situations. 4.1.7 inch high definition color screen, display real-time concentration and alarm status. 5. Optional high-temperature and high-humidity pretreatment system can detect high-temperature flue gas. 6. Equipped with data recovery function. 7. You can set whether to display MAX Maximum and MIN Minimum. 8. Various alarm methods: including 2 sets of relay switch output, sound and light alarm (optional), display visual alarm; alarm types include concentration alarm and fault alarm. 9. Multiple alarm mode settings: low alarm, high alarm, interval alarm, weighted average alarm. 10. With misoperation identification function, concentration calibrated misoperation can be automatically identified and prevented. 11. Zero automatic tracking, long-term use is not affected by zero drift. 12. The target point is multi-level calibrated to ensure the Linearity and accuracy of the measurement. 13. Chinese or English interface is optional. 14. Operating temperature range (-40~ + 70 ℃), support temperature compensation. 15. With logging function, record calibrating, maintenance, fault logs, provide Sensor life expiration reminder, next concentration calibrating time reminder. 16. Intrinsically safe circuit design, explosion-proof, with two-stage lightning protection, anti-static ability, anti-high-intensity pulse surge current Impact, with anti-reverse connection function, in line with EMI and CEMC standards.
The instrument uses a gas Sensor based on the principle of thermal conductivity for detection. When the target gas (benzene) enters the Sensor, it will cause a change in the Sensor's thermal conductivity, thereby changing the Sensor's electrical signal output. The instrument calculates the gas concentration by processing the electrical signal and displays it in real time on the display screen. When the concentration exceeds the preset alarm value, the instrument will trigger a sound and light alarm (optional) and output the corresponding control signal.

1. Installation: Choose the wall-mounted or pipeline installation method according to the site conditions, and connect the power supply and signal cable (such as three-core Shielding cable or four-core cable) as required. Power on: Connect to 12~ 30VDC DC power supply (standard is 24V). 3. Parameter setting: Through the standard infrared remote control, one-button operation can be performed without opening the lid in dangerous situations, and alarm points can be set, display units can be selected, alarm modes, etc. 4. calibrate: use infrared remote control for concentration calibrating or zero point calibrating, the instrument has the function of misoperation identification. 5. Monitoring: The instrument enters the 24-hour continuous online monitoring state, and the real-time concentration is displayed on the 1.7-inch color screen. 6. Data viewing and maintenance: Data, alarm records and equipment logs (such as calibrated logs and fault records) can be viewed through the display screen or remote monitoring system.
When installing, ensure that the connecting cable meets the requirements: 4~ 20mA output of three-core Shielding cable, RS485 output of four-core cable; transmission distance of more than 1000 meters, a single wire diameter should be ≥ 1.5mm, and the Shielding layer needs to be grounded. • Power requirements: DC regulated switching power supply with a standard power supply of 24V, 1A or greater than 1A for a single device. • Instrument Protection Rating is IP65, but environmental factors still need to be considered when installing. The built-in Filter can be used in high humidity or high dust environments. • Alarm point can be set as needed, providing 1 alarm output by default, optional 2 passive touchpoint output. • When performing concentration calibrating, please operate according to the specifications. Although the instrument has the function of misoperation identification, improper operation should still be avoided. • The instrument has the Sensor life expiration reminder function, please pay attention to the reminder and arrange maintenance or replacement in time. • Instrument working environment temperature is -40~ 70 ℃, humidity is 10~ 95% RH, beyond this range may affect performance. • Optional functions (such as wireless transmission, high temperature detection pretreatment system, on-site sound and light alarm, etc.) need to be clear when booking. • The explosion-proof mark of the instrument is Exia II CT6, which is suitable for the corresponding explosion-proof area. Installation and maintenance must comply with relevant safety regulations.
