Model 5000 Moisture Analyzer

Measurement Principle: oscillating quartz crystal micro-balance
Factory calibrated range: 0-1000 PPMV moisture in gas. Provides trend information up to 9999 PPMV for start-up purposes
Asymmetric cycling (10 minute cycle) between sample and reference gas using dried sample. Provides positive reference and decontamination of cell
Suitable for hydrogen recycle compressor suction side sampling
Rechargeable internal NIST traceable 20 PPMV moisture generator to provide periodic validation/performance check. Typical 5 year life.
Specific to water, no hydrogen or oxygen interference
No process temperature or pressure compensation required
Field unit w/sensor suitable for Cl. I, Div. 1, Group B, C, D
Microprocessor based control unit suitable for Cl. I, Div. 2, Group B,C, D, panel/wall/rack mount, can be separated up to 2000 ft from field unit
Control unit outputs: Bi-directional RS-485, dual 4-20mA analog outputs, and 3 alarm relays (32Vdc @ 1A non-inductive)
Power supply: 115V or 230V
Display: digital vacuum fluorescent displays PPMV, 15 psig operating pressure, 30-100 psig inlet pressure, 1500 ml/min gas flow
Accuracy: for 0-5: 0.1 PPMV; for 5-20: 1 PPMV; > 20 PPMV: 1% of reading
Sensitivity: 0.02 PPMV
Sample gas temperature: 0-100º C
Ambient operating conditions, field unit: -18º C (0º C w/out enclosure, i.e. field unit only) to 40º C, Controller: 0-52º C
