In some applications it is necessary to analyse gas in pressure lines or pressure-vessels. Part of it are analyses of chemical and physical composition and of content of particles in gases. Because of the specifications of common measuring devices that are often not made for sampling from pressure vessels, the use of a suitable sample extraction system is required, like the SYS 525.
- pressure uncoupling between measuring point and measuring device
- isokinetic and isoaxial sampling
- battery-operation possible
- display for observation and control of isokinetics
- aerosol sampling from pressurised systems
- acceptance and periodical evaluation of pressurised systems (VDI 2083-7)
- process monitoring in chemical industry, pharmaceutical manufacturing, food production, ...
- aerosol research
The sampling system SYS 525 places sample volume flow at the disposal of analysing device (e.g. the Airborne Particle Counter LAP 340) and realises the necessary pressure uncoupling. The total volume flow of 28,3 l/min is taken out of the pressure line. In a second step a sample volume flow of 28.3 l/min is taken isoaxial and isokinetic. The pressure uncoupling is made before the isokinetic sampling via a micro dosing valve. Correct sampling is realised by measuring the total volume flow with a sensor and by the special probe design and configuration. If the total volume flow deviates from setpoint of sample flow of particle counter the sampling system gives notice to the user via display. By adjusting the volume flow at the sampling system SYS 525 the isokinetic can be reset.
