Odor gas detector

1.Introduction to Odor gas detector product functions

Odor gas detector10 Any combination of odor gas parameters, real-time grasp the odor emission of the monitoring location.

1.The monitoring equipment can simultaneously monitor composite odorous gases (OU), volatile organic gases (TVOC) in the air, hydrogen sulfide, ammonia, and meteorological parameters (temperature, humidity).

2.The monitoring equipment has good anti-interference ability and self-recovery function after power failure.It has waterproof and dustproof design and supports GPRS wireless communication.

3.The monitoring equipment must comply with the "Data Transmission Standard for Online Pollutant Monitoring (Monitoring) Systems" HJ212-2017.

4.The monitoring equipment has an alarm function and adopts an integrated design, which can realize the light alarm function when the local monitoring factors exceed the standard.

5.The monitoring equipment has local and remote calibration functions, and is equipped with a pre-treatment system (to remove dust, water vapor and other impurities) and one-button silencing.

6.The main interface of the monitoring equipment displays a real-time curve for nearly 60 seconds, and the concentration value is displayed in digital and graphical form.

7.The monitoring equipment can be installed on a pole or on a wall.

8.Lifecycle management system: the system manages the life of major components and can issue alarms based on the remaining lifespan set;

9.The equipment needs to be equipped with a color touch screen to facilitate debugging and operation;

10.The equipment has expandable GPS positioning function, and the monitoring data can be stored in association with GPS positioning information;

11.Equipped with high-performance industrial-grade wireless module; equipped with high-performance industrial-grade 16/32-bit communication processor; equipped with complete anti-dropping mechanism to ensure that the data terminal is always online; RS232/RS485 interface.

12.Signal output: 4G wireless transmission function, RS-485

13.Working power: AC220V±10%, 50HZ, 5A

14.Working temperature: -30~70℃ (referring to the processor part)

15.Working humidity: 0~90%RH

16.Built-in 4G wireless communication module, can set and modify the wireless transmission data sending interval, sending IP/domain name address, support HJ212 protocol.Seamlessly connect to customers and environmental protection bureau platform, the last "real-time", "minute", "hour", "day" data.

Fengtu Technology Odor Gas Monitoring System Product Construction and Installation Plan

HJ 664-2013 Technical Specifications for the Layout of Ambient Air Quality Monitoring Points (Trial)

1.Installation environment

The installation environment should comply with the operating environment requirements of the environmental monitoring system (including ambient temperature, ambient humidity, and ambient pressure).Avoid areas with mechanical vibration, strong electromagnetic radiation, too fast air (wind speed), and too high ambient temperature and humidity.Too fast air flow will affect the response time and test results, and too high ambient temperature and humidity will affect the test results and the service life of the sensor.

2.Installation location

The general principle should take into account factors such as the diffusion space of the monitored gas, wind direction, ambient temperature, ambient humidity, closedness of the monitoring area, process pressure, and distribution of surrounding equipment.Areas where personnel are on duty or where personnel often stay should be given priority.

Guided installation

1.Pre-embedded foundation and construction with embedded parts

1.The middle frame of the cage is a square 21cm*21cm, 51cm high, and the distance between the hooks at the bottom is 31cm, as shown in Figure 1.The pre-buried construction size is not less than 50cm*50cm, and the depth is 40-43cm.

Figure 1

2.Find the horizontal position and place the embedded parts in the appropriate direction, with one front facing south.When pouring the embedded parts, be careful not to pour the concrete into the threading tube or on the embedded parts studs.The embedded parts should be placed straight in the pit, not skewed, and fixed to prevent the position of the embedded parts from changing when pouring concrete.See Figure 2.

3.Wiring: Reasonable wiring should be done in advance according to the order requirements, including power lines.If wiring is required, before pouring concrete, a threading tube should be placed.Usually, it is a plastic tube made of PVC material, and the diameter is determined according to the size of the power supply cable.The threading tube must be 5 cm higher than the central reserved hole of the embedded part, and the other end should be connected to the corresponding equipment.
