Système de test de qualité du gaz comprimé
A rugged portable multi-channel test system that combines pressure control, dedicated sample flows and modular sensing for particles, pressure dew point and oil-vapour screening in compressed air and compatible process gases.
- One case for multiple gas-quality channels.
- Dedicated pressure and flow control paths.
- Organized modules for repeatable field setup.
Introduction de produit
This integrated field system organizes several compressed-gas purity measurements inside one protective open-case platform. A central digital interface coordinates the selected sensor module and records stabilized results, while the analog pressure gauge, two different-range flowmeters and three color-coded regulators keep the particle, moisture and oil-vapour sample paths visibly separated. Three front sampling ports and short color-matched hoses reduce setup ambiguity at changing utility points. The removable sensor module and fitted storage bay support transport without turning the system into a loose collection of handheld instruments. Individual measurement channels are selected and conditioned for their intended contaminant rather than treating one sensor as a universal air-quality detector.
Key Features
Separate particle, moisture and oil-vapour sample ports maintain distinct flow and conditioning paths inside the case.
One analog inlet-pressure gauge provides a direct pneumatic check before gas is routed to a sensitive measurement module.
Two different-range variable-area flowmeters make low-flow sensor conditioning and higher-flow particle sampling visually distinguishable.
Three color-coded adjustment knobs correspond to the three sampling circuits and reduce connection errors during field setup.
Rugged open-case construction, a removable sensor module and fitted hose storage protect the complete kit during site-to-site transport.
Préoccupations du client produit
A meaningful compressed-gas quality survey must preserve the different sampling needs of particles, water and oil while documenting pressure, flow, test location and stabilization conditions for every channel.
One sample flow cannot represent particle, moisture and oil-vapour measurement requirements equally well.Route each contaminant channel through its designated port, regulator and flowmeter, then allow the selected sensor path to stabilize before recording a result.
Oil, condensate or dirty fittings can transfer contamination between test locations and bias later readings.Use clean capped hoses for each circuit, inspect the inlet before connection and purge or replace the appropriate sample path after an unexpected high-contamination event.
Pressure changes can alter flow and make consecutive site measurements difficult to compare.Check the analog inlet gauge, adjust the color-coded regulator for the active channel and confirm the appropriate flowmeter position throughout the test interval.
A single combined report can hide the sampling method behind each displayed value.Store the measurement point, gas, pressure, selected channel, stabilization period and sensor-module identity together with each particle, dew-point or oil-vapour result.
