In the field of industrial manufacturing, compressed air, as the "fourth largest energy source", directly affects production efficiency and product quality in terms of its quality.Ce Si Instrument (Shanghai) Co., Ltd. has established a detection system covering the three core parameters of residual oil, particles, and humidity with the authorization of German CS Instruments technology, providing solutions that comply with ISO 8573 standards for industries such as semiconductors, pharmaceuticals, and food.

　　1、 Residual oil detection: from microgram level to continuous monitoring

The OIL CHECK 500 series launched by the company adopts the photoelectric ion detector (PID) technology, which achieves zero calibration operation by burning hydrocarbons through a catalytic converter. The detection limit reaches 0.001mg/m ³ and can accurately monitor ISO 8573-1 Class 1 compressed air. Its innovative "forced pressure change" measurement method compensates for sensor aging drift by generating reference gas internally, ensuring long-term stability.

　　2、 Particle counting: nanometer level accuracy and full process traceability

For particle pollution control, the PC 400 optical particle counter of the measuring instrument adopts a laser diode and high-precision optical system, which can detect 0.1 μ m particles and meet the ISO 8573-4 Class 1 standard.

　　3、 Humidity control: Dew point monitoring and intelligent warning

The FA 510 dew point sensor is based on the capacitive principle, with a measurement range covering -80 ° C to+20 ° C, and can accurately capture faults in compressed air dryers. The Modbus protocol interface of the DS 500 recorder supports linkage with the PLC system, automatically starting the backup dryer when the dew point exceeds the limit to ensure production continuity.

　　4、 System Integration: From Single Machine Detection to Full Link Management

The AQ 500 series solution of the testing instrument integrates three major modules: residual oil, particles, and humidity, and achieves multi parameter synchronous monitoring and 4-level alarm output through the DS 500 recorder. In a certain electronic manufacturing enterprise, the system uploads data to the MES system through Ethernet interface, generates a daily report of compressed air quality, and helps the enterprise extend the equipment maintenance cycle from 3 months to 6 months.

From microgram level residual oil monitoring to nanometer level particle counting, from dew point intelligent warning to full chain data traceability, Testing Instrument (Shanghai) Co., Ltd. provides a dual wheel drive of "precision detection+intelligent management" to safeguard the quality of industrial compressed air. Its technical solution not only passes ISO 8573 certification, but also deeply integrates into the customer's production process, becoming a crucial "air guardian" in the field of advanced manufacturing.
