On-line dust concentration detector product parameters

On-line dust concentration detector product features

● Intrinsically safe circuit design, explosion-proof certification, secondary lightning protection, anti-static, lightning protection and anti-static capabilities exceed national standards, and resist high-intensity pulse surge current impact. High reliability and stability.

● Standard bus RS485 and 4 ~ 20mA standard signals are output at the same time, one group of relay switch output, optional frequency output 200-1000Hz, 1~5V output, wireless transmission (10-50km or unlimited distance). It can be wired or wireless remote real-time monitoring, upload data to mobile phones or transmit to the Environmental Protection Bureau, other monitoring centers, monitoring equipment, and monitoring computers through local area networks and the Internet, and monitor the concentration of the site in real time through free upper computer software or gas alarm controllers.

● Compatible with all kinds of secondary table, data acquisition module, PLC, DCS system, can directly drive the solenoid valve, fan, alarm and other equipment, can also drive the intermediate relay to drive high-power equipment.

● Standard infrared remote control, can be achieved in dangerous situations without open cover operation.

● 2.5 inch HD color screen (TF) shows real-time concentration, temperature and humidity.

● Automatic zero tracking to prevent drift, temperature compensation, multi-level calibration, can also meet the national standard and local and provincial metrology bureau standards in various regions.

Installation requirements and specifications for dust concentration measuring detector:

1: dust concentration measuring instrument, fixed, the design institute generally requires line installation
2: The place where the belt is transported is installed between 0.5-2 meters above the transfer point
3: production workshop, installation workshop pillars or about 2.5 meters on the wall
4: Where there is a grinder, install it between 0.5-2 meters above the grinder
5: The place where coal powder, flour, etc. are stacked is called the production point and installed above the production point. For example, coal powder is 15 meters high and should be installed 0.5-2 meters high, that is, about 18 meters.

Installation Method

Users can design their own fixed way. However, care should be taken to keep the sensor face of the probe perpendicular to the ground. After the probe is fixed, remove the screws on the upper cover of the shell, and insert the shielded (three-core 3 × 1.5mm) transmission cable through the wire passage. It is recommended to use shielded soft core (3 × 1.5mm) cable and connect the cable to the terminal position. After checking that the wiring is firm, fix the cable and the upper cover of the housing.
