3.1 MOUNTING THE TRANSMITTER
Surface mount the transmitter case on to a flat surface or bracket, using the four
mounting brackets provided. Make sure the ambient temperature is below 50°C, and that
the radiated heat from furnaces and boilers is kept to a minimum.
3.2a INSTALLING A 1231 OXYGEN PROBE
Weld a BSP or NPT socket to the flue in a suitable position for flue gas sensing.
For the correct size of socket refer to probe data in Section 1. The closer to the source of
combustion the smaller will be sensing lag time, allowing better control.
The probe has a typical response time of less than four seconds, so most of the
delay time is normally the transit time of the gas from the point of combustion to the point
of sensing.
Probes can be mounted at any angle. If there are any particulates in the flue gas,
a filter can be omitted by pointing the probe vertically downwards. Otherwise the filters
may have to be replaced periodically.
If installing a probe into a hot environment, slide the probe in slowly to avoid
thermal shock to the internal ceramic parts. If the flue gas is 1000°C (1830°F), it should
