The OPM 8000 Oxygen Analyser (%) manufactured by Orthodyne meets the requirements of industrial gas production. It includes the Paramagnetic sensor technology.
Principle
The automatic manufacturing process is capable of very high precision leading to levels of quality and reproducibility beyond anything that is currently available on the market.
With the possibility to set individual measuring ranges, it allows the analyzer to be easily tailored to specific measurement requirements. An outstanding characteristic of this analyzer is its long term stability. In most applications, calibration of the zero-point with ambient air or nitrogen is only required once a month. It is also suitable for measuring rapid changes in the concentration of the sample gas.
Measuring range - Various configurations possible
Analog Output signal - 2 x 4..20mA configurable
Digital Output - Ethernet-10/100BASE-T (standard)
4 x D/O configurable (standard)
Modbus RS232/485, Profibus DP/PA and Profinet (optional)
Linearity - < 0.5% of span
Repeatability - < 50ppm O2
Zero Drift - ≤ 3 % of span of the smallest measurement range per week
Sensitivity Drift - ≤ 0.1 Vol.-% O2 per week or ≤ 1 % of measured value per week (not cumulative), whichever is smaller.
Output Fluctuation (2 σ) - ≤ 25 ppm O2 at electronic T90 time (static /dynamic) = 3 / 0 sec
Detection Limit (4 σ)
- ≤ 50 ppm O2 at electronic T90 time (static /dynamic) = 3 / 0 sec
Warm-up (stability) time - < 1h
Response time T90
- T90 ≤ 4 sec at a sample gas flow of 90 l/h and electronic T90 time (static/dynamic) = 3 /0 sec, gas change from N2 to air
