The Novatech 1732 Oxygen Transmitter is designed to measure oxygen concentration in a range of combustion applications such as power stations and industrial boilers. The measurement is used to control the air / fuel ration in the burner to maintain efficiency and safe operation conditions.
Optimum combustion reduces your fuel bill and helps the whole world and future generations by reducing harmful greenhouse gas emissions. The current high cost of fuel has helped to reduce the payback period for the cost of installing oxygen monitoring and air / fuel ratio control.
The transmitter is designed to be used along with the range of Novatech heated and unheated oxygen probes. These probes use a zirconia sensor operating in environments up to 1400° (2010°F). The 1231 oxygen probe has an integrated heater, while the 1232 probe uses the process heat to heat the sensor. There is a unique cable connection between the 1732 transmitter and the 1231/1232/1234 probe.
It makes sense to consider the benefits of installing an oxygen system on your combustion process. The 1732 Oxygen Transmitter is suitable for gaseous oxygen measurements in a variety of processes.
