Description

TECHNICAL FIELD

[0001] The utility model relates to dust particle counter technical field, concretely is high pressure special gas laser dust particle counter. BACKGROUND

[0002] The laser dust particle counter is an instrument for measuring the number of dust particles in a unit volume and the particle size distribution in a clean environment. Its basic principle is that the probe laser of the optical sensor is received by the photosensitive element after being scattered by the dust particles and generates a pulse signal. The pulse signal is output and amplified, and then digital signal processing is carried out. By comparing with the standard particle signal, the comparison result is expressed by different parameters.

[0003] However, in the detection process of the existing laser dust particle counter for gas, the gas to be detected needs to be transported into the inside of the detection equipment. At the same time, after the gas is transmitted into the specific light source, the number of dust in the gas can be detected. However, in the detection process of high pressure gas, the pressure generated by the transportation of high pressure gas into the detection equipment will increase. The increased pressure will instantaneously exert pressure on the detection equipment, causing damage to the internal structure of the detection equipment, thereby affecting the service life of the detection equipment. Therefore, we propose a high pressure special gas laser dust particle counter. UTILITY MODEL CONTENTS

[0011] Preferably, the buffer structure shell is internally provided with a limiting baffle, and the limiting baffle is arranged at the upper portion of the piston.
