Detailed Product Description
CLJ-3016M laser transmitter dust particles for the measurement of a clean environment in the unit volume of air within the dust.
CLJ-3016M laser transmitter dust particles (hereinafter referred to as instrumentation) for the measurement of a clean environment in the unit volume of air within the dust particle size and number, and to correspond to the number of particles is converted to 1-5V or 4-20mA standard signal. Cleanliness level can be detected for the 100000-100 a clean environment.
Please indicate when ordering the cleanliness level.
The instrument uses the semiconductor laser source, small size, light weight, high detection precision, computer control, as long as the instrument can automatically output data at power-free operator. Therefore, test clean up the environment is very convenient. Are widely used in electronic, optical, chemical, food, cosmetics, pharmaceuticals, biological products, aviation and aerospace sectors.

C, the working principle and function of
This instrument uses light scattering theory, when the suspended particulates in the air through the light-sensitive area, the scattering of a particle into a certain proportion of their luminous flux by photoelectric conversion, amplification, and after treatment were collected to be equivalent particle diameter and the number and the number of particles into 1-5V or 4-20mA signal.
D,The use steps
1. Installation: First the fixed equipment stent (stent may also be determined by the user to provide the seller), and the instrument placed in the bracket has been positioned.
2. Wiring: Recommended to use 5-core shielded cable, in which two cores for power input, and 2-core for signal output, shield a termination 0V the other side as a signal of the zero line, as shown below. Transducer Interface Pin Definition: 1 foot 12V/1A input 2 pin 0.3um 4-20mA/1-5V 3 feet 0.5um 4-20mA/1-5V 4-pin 0V
3. When wiring is correct after the power-on, open the instrument power switch. Power is switched on when the device about 10S of time self-test process, when 2,3-feet respectively, the output 0 current (voltage) and full range current (voltage) signal, the user should detect these two signal values, respectively, as ( I030 / I050), and (I03F / I05F) value with 240 load resistor (V030 / V050), and (V03F / V05F) values used.
4. Instrument self-test, after each subsequent 60S data from a standard 2,3-pin output signal values. For example, to display the value displayed on the concentration of particles can be calculated as follows, the unit stars / m3:
0.3um = (I-I030) / (I03F-I030) * ISO14644 * 2
0.5um = (I-I050) / (I05F-I050) * ISO14644 * 2
