Novatech Controls 1231 Oxygen Probes Description

The Novatech 1231 Oxygen Probes incorporate the world’s most rugged zirconia sensors.

Ideal for:

  • Flue gas analysis
  • Oxygen levels in boilers, kilns and furnaces
  • Combustibles analysis
  • Carbon potential measurement
  • Water vapour concentration and dew point measurement
  • Inert and sterile packaging
  • General industrial use
  • Annealing furnaces

The Novatech 1231 Oxygen Probes are Australian-made and embody the research and development of one of Australia’s premier research organisations, the CSIRO.
The Novatech 1231 Probes are highly accurate, and have minimal drift (±1%).
The Novatech in situ probes are highly durable; choose the Novatech 1231 for analysing gases with temperatures below 900ºC.

The Novatech 1231 Probes have a very rapid response to changes in oxygen levels
A response time of between 1 and 4 seconds to oxygen level concentration changes means that potentially hazardous situations such as those caused through the build-up of dangerous, fuel-rich conditions can be avoided.

The Novatech 1231 Probes are easy to install
The probes are inserted into the flue, or other measuring point, and the threaded nipple (1231 has 1.5 “ BSP/NPT) is screwed on to a mating socket welded to the process. Connect the probe cable to the transmitter, and you are ready to measure and/or control the combustion process.

Novatech offers you safety of operation
Use the Novatech 1732 which has a main burner safety interlock. This is the ONLY reliable way of preventing potentially explosive situations; SHOULD THE MAIN BURNER FAIL OR SHUT DOWN THEN THE
SENSOR’S HEATER IS DE-ENERGISED SO THAT DANGEROUS FLUE GASES CANNOT BE IGNITED BY THE PROBE!

Notes:

  1. Care must be taken to avoid contact with explosive or inflammable gases with 1231 heated Oxygen Probes when hot. Novatech Oxygen Transmitters have built-in safety protection which disconnects the heater when the main flame is off.
  2. A 1231 Oxygen Probe has an integral type K thermocouple which is used to control the sensor temperature.
  3. The precise weight of a probe will vary slightly depending on the configuration of head connectors and filters.
  4. Probes exceeding 1000mm (40”) in length must be mounted vertically in the process.
