REMOTE5102

The 5102 online laser dust particle counter is used to measure the size and number of dust particles per unit volume of air in a clean environment, and transmit the number of corresponding particles to the host computer through MODBUS485 communication. It can control the clean environment with cleanliness level of 100,000 to 100.   This instrument adopts imported semiconductor laser light source, small in size, light in weight, high in detection accuracy, and computer controlled. As long as the instrument is powered on, it can automatically output data without personnel operation. Therefore, it is very convenient to test a clean environment. It is widely used in electronics, optics, chemistry, food, cosmetics, medicine and health, biological products, aerospace and other sectors.

Description

1. Introduction to counter application

The 5102 online laser dust particle counter is used to measure the size and number of dust particles per unit volume of air in a clean environment, and transmit the number of corresponding particles to the host computer through MODBUS485 communication. It can control the clean environment with cleanliness level of 100,000 to 100.

This instrument adopts imported semiconductor laser light source, small in size, light in weight, high in detection accuracy, and computer controlled. As long as the instrument is powered on, it can automatically output data without personnel operation. Therefore, it is very convenient to test a clean environment. It is widely used in electronics, optics, chemistry, food, cosmetics, medicine and health, biological products, aerospace and other sectors.

  2. Main technical parameters

  1. Dimensions 140*100*45;

  2. The mass is about 0.3kg

  3. Maximum power consumption 2VA

  4. External power supply 12-14VDC/1A

  5. Standard signal diameter channel 0.3-5μm optional 2, standard 0.5, 5μm

  6. Sampling flow 28.3LPM

  7. The sampling period is 1 minute

  8. Use environment temperature: 0℃-40℃ Humidity: 20%-75%

  Ambient pressure and sampled gas pressure: 86kPa-106kPa

  9. The maximum allowable sampling concentration is 35000 particles/L (the particle size of dust particles is not more than 0.5μm), and the sampling air must not contain corrosive gases such as acid and alkali

  10. Self-cleaning time≤10min

  3. Working principle

  This instrument uses the principle of light scattering. When suspended particles in the air pass through the photosensitive area, they scatter light flux in proportion to their particle size. After photoelectric conversion, amplification and processing, the equivalent diameter and number of collected particles are obtained, and the number of particles is passed through MODBUS485 transmission.

  4. Installation

  Know the counter before installation, as shown in the figure below. It is composed of protective cover, constant velocity sampling port, entity, electrical connection plug, sampling hose, ø32 stainless steel tube, quick connector, etc.

  According to the specific situation in the room and the requirements of GMP regulations, ø32 stainless steel pipes are pre-laid and installed, and ø32 stainless steel quick joints are welded at the pipe joints to realize quick connection and fixation with the counter. The sampling pipe and electrical connection line of the counter pass through the stainless steel pipe.

  5. Electrical connection

  4-pin aviation plug male and female quick link. The pin definition is as follows:

  1 Red-----+7.4~12VDC

  2 Yellow or green-----A

  3 White or blue-----B

  4 black-----GND

  Counter interface pin definition: ①pin (red wire) DC positive input ②pin (yellow or green wire) 485 A

  ③Pin (white or blue wire) 485 B ④Pin (black wire) DC0V.

  It is recommended to use a 2-core twisted-pair shielded wire for the communication wire, and the wire diameter can be 0.5mm. One end of the shielding layer must be connected to one end of DC0V.

  The DC input range is 7.4V-12V, and the wire diameter can be 0.5-1.0. It should be noted that if the distance between the power supply and the counter is far, because of the line voltage drop, if the voltage supplied to the counter is lower than 7V, it may cause the counter to not work normally.

  6. Gas connection

  The system should provide a vacuum system for counter sampling. The pre-installed gas hose is quickly connected to the sampling hose of the counter with a straight-through. Each path on the gas path is also composed of solenoid valves, flow sensors, throttle valves and other departments. Before the counter is used for the first time, the throttle valve opening should be adjusted so that the sampling flow detection display of the counter reaches the legal 28.3 liters/minute (1CFM).

  7. Disinfection, cleaning and maintenance

  10.1 Service Agreement

  Note that the instrument has no user-maintained parts. It is not allowed to open the instrument during maintenance, calibration or any other purpose without professional personnel authorized by Hongji Company. The purpose of this warning is that there may be a risk of blindness due to invisible laser radiation inside.

  The maintenance and replacement of sensors and circuit boards need to be carried out by professionals, please contact Hongji Company. Calibration instruments require specialized equipment and professional technology. Hongji's counting technology for calibrating the instrument is a generally accepted method in the industry, such as ASTM and JIS traceable to NIST standards.

  The transmitter is calibrated once a year.
