DESCRIPTION
The transmitter is used for measuring Oxygen (O
2
) concentration into flue gases.
TS236 model is supplied with a standard Probe Body supporting flue gases temperature up to 30C.
TS237 model is supplied with a standard Probe Body supporting flue gases temperature up to 60C.
Consider that this instrument has not been designed as a security control system, therefore, if used for
the control of air as supporter of combustion, you need all possible measures to avoid danger
situations or whole plant stop in case of its fault.
The Oxygen Transmitter is composed by aluminium housing with dimensions 210 x 110 x 120 mm with
protection range IP55. Inside the housing there are: the power supply circuit, the oxygen concentration
measuring circuit and the terminals for the external connections. The probe is connected to the
housing by 1 meter cable.
INSTALLATION
The Oxygen Transmitter unit has to be installed near the boiler to analyze. The Oxygen probe has to
be placed on the chimney pipe fitting to a distance equivalent to two diameters of the pipe fitting itself.
The distance between the probe and the housing is bound by the 1 meter cable connection.

If the chimney pipe fitting is too short, you can fix the probe directly on the chimney to a distance
equivalent to two diameters of itself from the connection to the pipe fitting.
