Mini-OX
Oxygen sensor for control in low temperature applications.
Ideal for package boilers, the Mini-OX in-situ oxygen sensor measures %Oxygen concentrations in the exhaust of furnaces, boilers and other applications.
| Features: |
| High accuracy linear output |
| Externally triggered automatic calibration |
| Can be calibrated in normal air |
| Mating connector supplied |
| Suitable for replacement of Honeywell MF010 and MF020 oxygen sensors |
| Technical Specifications: |
| Supply voltage | 24VDC +/- 10% |
| Supply current | 500mA max at 24VDC |
| Analog output | 4-20mA; load 600Ω max
0-10VDC; load 10kΩ max |
| Housing temperature limits | 14°F to 185°F (-10°C to +85°C) |
| Permissable gas temperatures (probe tip) | -148°F to +752°F (-100°C to +400°C) |
| Gas flow rate | 0 to 33 ft/s (10 m/s) |
| Oxygen range (analog output) | 0.1 - 25% O2 (see Note 1 below) |
| Accuracy after calibration | 1% O2 (see Notes 2 and 3 below) |
| Repeatability after calibration | 0.5% O2 (see Notes 2 and 3 below) |
| Warm up time (prior to sensor operation) | 60s |
| Output stabilization time | ~180s |
NOTES:
1) Prolonged operation below 0.1% O2 can damage the sensing element.
2) Assuming barometric pressure remains constant.
3) As the O2 sensor measures the partial pressure of oxygen within the measurement gas, deviations in the barometric pressure from that present during calibration will cause readout errors proportional to the change.
Example: If the sensor reads 21% O2 at 1013.25mbar and the barometric pressure increases by 1%, the sensor readout will also increase by 1% to 21.21% O2
