Precise measuring directly at the test object

The ZEDsatellite decentralized measuring and testing modules enable measuring directly at the test object, increasing measuring accuracy and reliability.

The data from the available measuring methods can be easily read out centrally via ZEDbox or any other unit from the ZED device family.

Technical data: Relative pressure Differential pressure Accumulation pressure Mass flow Flow rate
Test pressure range Vacuum – 232 psi / 16 bar 0 – 6 bar Vacuum – 116 psi / 6 bar
Test pressure accuracy 1% of the end value 1% of the end value 1% of the end value 1% of the end value
Measuring range As with test pressure range – 1.45 – 1.45 psi – 100 – 100 mbar 10,000 – 450,000 ccm/min | ml/min -50 – 50 or -250 – 250 ccm/min | ml/min up to 250,000 ccm/min | ml/min
Measurement resolution 0.5 ppm of the end value
Smallest measurable pressure change (type-specific) 0.5 Pa (14.50 psi / 1 bar) – 4 Pa (232 psi / 16 bar) 0.1 Pa 0.1 Pa (50 mbar) – 1.5 Pa (6 bar)    
Measuring accuracy (leak rate) Depending on the test setup Depending on the test setup Typically 5% of the measured value, no smaller than 0.5% of the end value
Repeatability Depending on the test setup Depending on the test setup 0.5% of the measured value, no smaller than 0.05% of the end value (depending on the test setup)
