DM-2510T Dust Particle Counter Measurement Meter

MAS-I Micro Air Station

Description

DM-2510T online dust meter is suitable for rapid determination of the concentration of respirable particulate matter in the atmospheric environment, detection of dust concentration in labor hygiene aspects such as production sites of industrial and mining enterprises, and monitoring of respirable dust concentration in the field of environmental protection.

This product adopts a special optical cavity design and introduces sheath gas to protect the entire optical cavity, thereby reducing the contamination of the optical cavity by dust particles to a great extent and reducing the maintenance workload.
The product design complies with the JJG846-2015 standard and has been widely used in real-time monitoring of dust concentration in public places such as construction sites, industrial and mining enterprises, storage yards and docks. It can more quickly and directly observe the continuous changes in atmospheric dust concentration, which is in line with relevant industry standards. Laws, regulations and standards can also effectively improve work efficiency and can be applied both indoors and outdoors.

Specification

Function and definition
Sampling port: Please remove the protective cover of the sampling port before using the product.

Exhaust port: Do not close the exhaust port during use.

External filter:

When replacing the external filter, please pay attention to the direction of the arrow and do not allow reverse access to the air path.

Terminal wiring definition:

The wiring terminals (as shown in the picture above) are numbered 1-8 from left to right.

The wiring definition of input and communication is as shown in the following table:

MODBUS-RTU protocol description
Brief description of the agreement
Byte transmission method

lBaud rate: 9600

l1 starting bits

l8 data bits

lNo parity bit

lError checking (Error Checking) CRC (cyclic redundancy check, low byte first then high byte)

Protocol data frame format

Address field

Only 1-247 is used in the meter, other addresses are reserved. FCH is the broadcast address.

Function domain

Error checking methods

The process of generating a CRC is:

l Pre-prepare a 16-bit register bit FFFFH (all 1), called CRC register;

l Perform an XOR operation on the 8-bit bytes in the data frame and the low byte in the CRC register, and store the result in the CRC register;

l Shift the CRC register one bit to the right, fill the bit with 0, and move the lower limit bit out and detect it;

lIf the lower limit is 0: repeat step 3 (next shift);

lIf the lower limit is 1:

XOR the CRC register with a preset fixed value (A001H);

Repeat the third and fourth steps until 8 shifts, so that a complete eight bits are processed;

Repeat steps 2 to 5 to process the next eight bits until all bytes are processed;

The value of the CRC register is the value of the CRC.

There is also a method of calculating CRC using a preset table. Its main feature is fast calculation speed, but the table requires a large storage space. I will not go into details here. Please refer to the relevant information.

Detailed explanation of communication format

Read data (function code 03)

The obtained data is converted into actual values according to the corresponding data item type.

Command example: read PM2.5 data, address 01H, read length is limited, word mode

Set a single register (function code 06)

Function code 06H allows the user to change the contents of a single register

Command example: Set the instrument working period to 15 seconds, address 01H

Parameter address list

illustrate:

lData type: "Word" refers to a 16-bit unsigned integer;

"DWord" refers to a 32-bit unsigned integer.

l Read and write attributes: "R" is read-only, "R/W" is readable and writable, and it is prohibited to write data to addresses that are not listed or do not have writable attributes;

lThe dust concentration is a 32-bit unsigned integer. The high and low bits each occupy an address, with the low bit in front and the high bit in the back. Multiply the high-digit value by 65536 and add the low-digit value to obtain the parameter value, and then divide by 10 to obtain the actual value of the parameter (unit: μg/m³).

lIn order to simplify the user's operating instructions, you can use the 03H instruction to read the PM parameter address, and the instrument will automatically start, eliminating the need to send instructions to write instrument status, making it convenient for users to operate the equipment.

safety regulations
Precautions:
To ensure the reliable use of the equipment and the safety of personnel, please comply with the following matters during installation, use and maintenance:
lWhen installing the equipment, make sure that the ground wire in the power cord is well grounded, and ensure that the input power of the equipment is DC 12V;

lDo not place system equipment in a place that is too cold or too hot;

lThe power supply of the equipment will generate heat when working, so the working environment must be well ventilated to avoid excessive temperature and damage to the machine;

l In rainy and humid weather or when not in use for a long time, the main power switch of the equipment should be turned off;

lNon-technical personnel should not attempt to disassemble the equipment without permission, and do not repair it without permission to avoid accidents or aggravated equipment damage.

other
