The GAOPIN NGP5-C6H6-A stationary benzene alarm instrument is an online benzene Gas detector for 24-hour continuous online monitoring of gas concentration in the field. The instrument uses a thermal conductivity principle Sensor, equipped with a 1.7-inch high definition color screen to display on-site concentration, and supports on-site sound and light alarm (optional) and remote signal transmission. Its rugged explosion-proof housing is suitable for various hazardous locations and harsh industrial environments.
1. Units can be switched freely. 2. Diversified communication methods: real-time monitoring can be carried out through wired or wireless remote transmission and network transmission; support three-wire 4~ 20mA standard signal and standard bus RS485 (modbus-RTU) simultaneous output; optional frequency output 200-1000Hz, Hart protocol signal, 1~ 5V output, two-wire 4~ 20mA, SMS alarm, wireless transmission. 3. Standard infrared remote control, which can be operated without opening the lid in dangerous situations. 4.1.7 inch high definition color screen, display real-time concentration, alarm status. 5. Optional high-temperature and high-humidity pretreatment system can detect high-temperature flue gas. 6. Data recovery function, in case of wrong operation, you can choose partial or full recovery. 7. You can set whether to display MAX Maximum and MIN Minimum. 8. A variety of alarm methods, including: 2 sets of relay switch output, sound and light alarm (optional), display visual alarm. Alarm types include: concentration alarm, fault alarm. 9. Multiple alarm mode settings: low alarm, high alarm, interval alarm, weighted average alarm. 10. Misoperation identification function: concentration calibrated misoperation automatic identification and prevention. 11. Zero automatic tracking, long-term use is not affected by zero drift. 12. Target point multi-level calibrated to ensure Linearity and accuracy of measurement. 13. Chinese or English interface is optional. 14. operating temperature: -40~ + 70 ℃, support temperature compensation. 15. Logging: record calibrating logs, maintenance logs, fault records, fault solutions, Sensor life expiration reminders, next concentration calibrating time reminders. 16. Intrinsically safe circuit design, explosion-proof, with secondary lightning protection and anti-static capabilities. With anti-reverse connection function.
The instrument adopts the Sensor of thermal conductivity principle to measure the concentration of benzene (C6H6) gas by detecting the change of gas thermal conductivity. The instrument continuously monitors the gas on site and converts the concentration signal into a standard electrical signal output.

1. Install the instrument correctly, choose Wall-Mounted or Pipeline installation. 2. Connect the power supply (12~ 30VDC DC, the standard is 24V) and the signal output cable (such as 4~ 20mA or RS485). 3. Use the standard infrared remote control for one-button operation, which can perform alarm point setting, concentration calibrating, zero point calibrating, muffling, factory recovery and other operations. 4. After the instrument is powered on, observe the real-time concentration and equipment status through the 1.7-inch high definition color screen. 5. Transmit data to a remote monitoring center via wired or wireless means, as required.
* When installing, pay attention to the requirements of Protection Rating (IP65) and Explosion Mark (Exia II CT6) to ensure that it is suitable for the on-site environment. When connecting cables, a three-core Shielding cable is recommended for 4 to 20mA output, and a four-core cable is recommended for RS485 output. When the transmission distance exceeds 1000 meters, the single wire diameter should be ≥ 1.5mm, and the Shielding layer needs to be grounded. * Power configuration: The standard power supply of a single device is 24V, 1A or greater than 1A DC regulated switching power supply. A 24V, 2.1A switching power supply can drive 40 toxic Gas detectors, or 15 combustible, infrared Gas detectors. * The built-in Filter of the instrument can be used in high humidity or high dust environment, but the working environment humidity should be ≤ 10~ 95% RH. * When performing concentration calibrating, the instrument has the function of misoperation identification, but it still needs to be operated according to the specifications. * Optional functions (such as wireless transmission, high temperature detection pretreatment system, on-site sound and light alarm, etc.) need to be clear when booking. * Regularly check the instrument log, pay attention to the Sensor life expiration reminder and the next concentration calibrating time reminder.
