Systèmes utilitaires Cleanroom
Système de surveillance de la qualité de l'air comprimé
A fixed wall-mounted analyzer that brings one pressure-dew-point channel, one oil-vapor channel and one laser particle-count channel into a single conditioned sample path, touchscreen display and networked alarm record.
- Dew point, oil vapor and particle monitoring
- Single conditioned 6 mm sample inlet
- Touchscreen logging with plant-network outputs
Introduction de produit
The Compressed Air Quality Monitoring System provides continuous indication of the three contaminant groups most commonly specified for clean compressed air: water vapor, oil vapor and particles. The selected purchasable configuration is one powder-coated steel wall cabinet with a 5-inch color HMI and one three-color status beacon, mounted above one fixed stainless-steel sample-conditioning panel on a shared wall frame. The panel feeds exactly one combined polymer/QCM dew-point channel, one PID oil-vapor channel and one laser particle-count channel from a single 6 mm inlet, then directs the measured sample to one controlled exhaust connection. Logged values, alarm states and plant integration are handled locally through Ethernet and RS-485 interfaces. It monitors a prepared sample; it does not dry, filter, compress or sterilize the utility air.
Key Features
A single regulated sample-conditioning path stabilizes the inlet before the flow divides inside the analyzer assembly
The 5-inch color HMI presents current values, trends and alarm states without requiring a separate workstation at the monitoring point
Integrated data logging supports trend review and investigation of short contamination excursions that periodic spot checks may miss
Modbus TCP over Ethernet and Modbus RTU over RS-485 provide two practical routes for connection to a supervisory or facility monitoring system
The powder-coated metal cabinet and dedicated wall frame keep the analytical modules, wiring and sample tubing together as one maintainable system
A front pressure gauge, one sample inlet and one exhaust connection make the sample route visually traceable during inspection and service
Individually replaceable sensing modules allow the measuring configuration and service plan to be matched to the required compressed-air duty
Préoccupations du client produit
A continuous analyzer is only useful when its sampling point, flow conditioning, alarm limits and maintenance regime represent the air that reaches the process.
A long or poorly purged sample line can delay the response to a real moisture or oil-vapor excursionInstall the cabinet close to the selected monitoring point, use clean PTFE sample tubing, minimize dead volume and purge the line before placing the trend data in service.
Condensate or excessive inlet pressure can damage sensitive analytical channels or distort their readingsUse the fixed conditioner and pressure indication, remain within the selected 0.3-1.5 MPa inlet envelope, and sample only non-condensing air within the specified temperature and humidity limits.
Particle counts can be biased when sample flow and take-off geometry do not represent the main compressed-air streamSelect an appropriate sampling point and flow arrangement, verify the particle-channel flow, and use an isokinetic sampling accessory when the applicable measurement plan requires it.
Operators may treat a green status light as proof that every ISO purity requirement has been independently certifiedSet alarm thresholds from the user's defined air-quality specification and evaluate results with the applicable sampling and test method; the monitor supplies evidence, not an automatic certification.
Expired service parts or contaminated tubing can create slow drift that looks like a process changeMaintain a documented zero, purge, calibration and consumables schedule for each sensing channel, and review long-term drift alongside dryer and filter maintenance events.
Les applications typiques
Pharmaceutical manufacturing compressed-air headers serving direct and indirect product-contact pointsMedical-device assembly lines that need continuous utility-air trend recordsFood and beverage filling or packaging systems supplied with treated compressed airElectronics and semiconductor processes sensitive to particles, moisture or hydrocarbon vaporLaboratory and biotechnology utility branches where point-of-use air quality can affect equipment performanceCentral compressed-air treatment rooms requiring early warning of dryer, filter or separator deterioration
Paramètres techniques
The locked catalogue configuration is one complete wall-mounted monitoring assembly, not a loose sensor set. It contains exactly one light-gray powder-coated analysis cabinet, one black-bezel 5-inch HMI, one red/amber/green stack beacon, one stainless sample-conditioning panel, one nickel-plated pressure regulator, one round pressure gauge, one polymer/QCM dew-point flow cell, one PID oil-vapor module and one laser particle-counter module. The sample hardware has exactly one 6 mm nickel-plated compressed-air inlet and one PTFE exhaust connection. Electrical interfaces are exactly one RJ45 Ethernet port, one M12 RS-485 port and one mains cable gland, carried on two rear wall rails with four mounting ears. The selected conservative operating envelope is 0.3-1.5 MPa(g), pressure dew point -100 to +20°C Td, oil vapor 0.001-5.000 mg/m³ and particle channels beginning at 0.1 µm. A final measurement plan must define the sampling location, applicable particle channel option, alarm limits and service intervals.
