ZIROX Electronic Unit E2000 Properties 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 according to the NERNST equation to the oxygen concentration (normally in vol%) and generated via standard interfaces. The electronic unit E2000 supplies the probe with reference air via internal pump. Additionally, the E2000 realizes the power supply and the heater control for heated ZIROX probes. Furthermore, the probes are monitored by the E2000 with cyclical measurements of the cell resistance. An error message is signalized if necessary. The user can program two limit values (output via relay). If requested, the E2000 can be delivered with automatic calibration function. In incomplete burned gases (reducing conditions), more values can be calculated (air factor X, dew point, H2O/H2-ratio, CO2/CO-ratio, c(CO2) and c(H2O) at water-gas-equilibrium). Precondition: known fuel gas composition, e.g. C/H-ratio.
