Probe Electronics E2000

General Information

The electronic unit E2000 is a comfortable device for the use of ZIROX oxygen probes.
The signals of ZIROX probes are recorded with the E2000, processed to the oxygen concentration (normally in Vol.-%) according to the NERNST equation and provided by
standard interfaces.

The electronic unit E2000 supplies the probe with reference air via internal pump.
Additionally, the E2000 accomplishes the power supply and the heating control for heated ZIROX probes. Furthermore, the probes are monitored by the E2000 via cyclic measurements of
the cell resistance. An error message is displayed, as necessary.

The user can program two limit values (output via relay).
In incompletely burnt gases (reducing conditions) more values can be calculated (air factor , dew point, H2O/H2-ratio, CO2/CO-ratio, c(CO2) and c(H2O) in the water gas equilibrium. Precondition: known fuel gas composition, e.g. C/H-ratio

If requested, the E2000 can be delivered with an automatic calibration function.

Features

  • Signal processing and display of ZIROX probes measuring values
  • Calibration and monitoring function for ZIROX probes
  • Measuring value output via standard interfaces
  • Process monitoring via standard interfaces
  • Customized solutions
  • Auto-calibration function (option)
