Overview
GAOPIN NGP5-O3-A Fixed Ozone Alarm Instrument is an online ozone Gas detector, which is used for 24-hour continuous online monitoring of gas concentration in the field. The 1.7-inch high definition color screen shows the on-site concentration, and supports on-site sound and light alarm (optional) and remote signal transmission. The instrument adopts electrochemistry principle Sensor, which is suitable for detecting ozone concentration in pipelines, confined spaces or atmospheric environments. The rugged explosion-proof shell makes it suitable for various hazardous places and harsh industrial environments.

Principle
The stationary ozone alarm instrument uses the Sensor of electrochemistry principle for detection. The instrument uses the diffusion type (optional pipeline type, circulation type, pump suction type) Sampling method to continuously monitor the ozone gas in the field environment, converts the gas concentration signal into an electrical signal, and displays the real-time concentration on the 1.7-inch high definition color screen after processing, and outputs the signal or triggers the alarm through various communication methods.
Applications
Petroleum, chemical industry, metallurgy, refining, gas transmission and distribution, biochemical
Standards
EMI, CEMC, explosion-proof mark: Exia II CT6 Certificate number: CNEx15.1283
Steps
1. Installation: Choose wall-mounted or pipeline installation methods according to requirements, and connect cables as required (4~ 20mA output chooses three-core Shielding cable, RS485 output chooses four-core).
2. Power on: Connect to 12~ 30VDC DC power supply (standard 24V, 1A or greater than 1A DC regulated switching power supply).
3. Parameter setting: Use the standard infrared remote control for lid-free operation, which can set alarm points, select display units, set alarm modes, etc.
4 calibrating: concentration calibrating or zero point calibrating by infrared remote control, the instrument has the function of misoperation identification.
5. Monitoring: The instrument starts continuous online monitoring, real-time concentration is displayed on the screen, and data is transmitted through optional communication methods.
6. Maintenance: Sensor replacement or regular calibrating according to logged reminders.
Notice
● When installing, pay attention to the Protection Rating of IP65 to ensure that it is used in the corresponding environment.
When connecting the cable, if the transmission distance exceeds 1000 meters, the single wire diameter should be ≥ 1.5mm, and the Shielding layer needs to be connected to the earth.
● Power configuration should be noted: 24V, 2.1A switching power supply can drive 40 toxic Gas detectors, or 15 combustible, infrared Gas detectors.
● The built-in Filter can be used in high humidity or high dust environment, but the working environment Humidity range is ≤ 10~ 95% RH.
● When selecting on-site sound and light alarm, wireless transmission, high temperature and high humidity pretreatment system and other functions, it needs to be clear when booking.
● When calibrating, the operating procedures should be followed, and the instrument has the function of misoperation identification but still needs to be cautious.
● Sensor life is 2~ 3 years, you need to pay attention to the life expiration reminder in the log and replace it in time.
The instrument is explosion-proof, but the installation and use still need to comply with the safety regulations of the relevant dangerous places.
