Model 3050 Moisture Analyzer Series

The Model 3050 Moisture Analyzer series measures trace levels of moisture in a gas through the use of a quartz-crystal oscillator sample cell.

Description

The Model 3050 Moisture Analyzer series measures trace levels of moisture in a gas through the use of a quartz-crystal oscillator sample cell. AMETEK is the leader in quartz-crystal technology, which for thirty years has offered significant advantages over other measurement techniques:

  • It is the most accurate trace moisture measurement technology available.
  • It responds far faster to both increasing and decreasing moisture levels.
  • It is specific to moisture in most applications.
  • It provides a much more rugged sensor.

Because of these advantages, the quartz-crystal oscillator has become the industry standard for applications ranging from ultrahigh purity semiconductor gases to natural gas streams containing 30% H2S. Now, the Model 3050 analyzers bring the benefits of quartz-crystal technology to a broad spectrum of moisture applications.

Specifications

See individual Specification Sheets on the Documentation tab for other Model 3050 versions.

Technology Quartz-crystal microbalance
Range Calibrated from 0.1 to 2500 ppmv.  Readout capability in ppmw, lb/mmscf, mg/Nm3 and dew point in ºC or ºF (requires process pressure as an input)
Reference Gas Continuously produced using actual sample gas
Online Verification Internal moisture source with NIST-traceable calibration enables on-demand verification of analyzer accuracy and responsiveness without uninstalling the analyzer
Accuracy ±10% of reading from 1 to 2500 ppmv with standard calibration; special calibration ranges not required
Reproducibility ±5.0% of reading from 1 to 2500 ppmv
Limits of Detection 0.1 ppmv
A/D Resolution 16-bit (0.0015%)
QCM Response Time Near real time. Computer-enhanced response, which may lead to errors is not required to obtain quick wet-up or dry-down response
Sensitivity 0.1 ppmv or 1% of reading, whichever is greater
Allowable Inlet Pressure 1.3 to 3.3 Bar (20 to 50 psi) gauge; up to 200 Bar (3000 psi) with optional pressure reducer; analyzer performance is independent of process pressure
Exhaust Pressure 0 to 1 Bar (0 to 15 psi) gauge
Sample Gas Temperature 0 to 100ºC (32º to 212ºF); analyzer performance is immune to changes in sample gas
Gas Flow Requirements Approx.150 sccm. Approx. 1.0 slpm bypass flow for increased speed of response
Outputs Isolated 4-to-20 mA analog signal, 12 bit (0.025%) resolution, RS232 and RS484 serial communication ports (supports Modbus RTU)
Alarms Three contact closures; system, data valid, and concentration alarms
