SAX 200

SAx 200 is a compact Flame Scanner. The flame sensor receives the optical waves emitted from the flame through a side glass in the combustion chamber, and converts it to the electrical signal by a opto-detector. Then, the signal received from the opto-detector is analyzed in the digital processor and the features of the flame quality are extracted.

SAx 200 Flame Scanner

SAx 200 is a compact Flame Scanner. The flame sensor receives the optical waves emitted from the flame through a side glass in the combustion chamber, and converts it to the electrical signal by a opto-detector. Then, the signal received from the opto-detector is analyzed in the digital processor and the features of the flame quality are extracted. The flame quality features are sent to the control room via a RS485 network,  4 … 20mA hard wire and a dry contact. The system is capable of operating in severe temperature conditions such as 70 ° C.

SAx 200 Flame Scanner Advantages

A digital 32-bit ARM family processor is used in SAx 200 flame scanner. In addition to performing the main task of Flame Scanner, this processor also offers the following new features

 

  1. The digital scanner is capable of recognizing the percentage of optical spectrum, i.e. how much of the received spectrum from the flame is UV and how much is IR. With this feature, it is possible to measure the flame quality inside the combustion chamber and compare it with an ideal flame.
  2. The ability to detect the flame intensity inside the combustion chamber.
  3. The digital scanner has a special software that can detect flame status and check it by connecting to the monitoring card (fig.7).
  4. Temperature recording inside the scanner in the long run allows to check the temperature inside the scanner. Thus, the issues of the side glass cracking and hot air leakage can easily be detected by checking the scanner temperature.
  5. Digital data transfer in physical layer of RS485 and Modbus protocol. This method of transferring data is immune to the environmental noise, and the destructive effects of disturbing signals is very low.

Input / Output Signals of the Flame Detector

The electrical connection of the flame sensor and flame analysis card is carried out by a 12- string cable. Two strings are for 24V voltage supply from the analysis card to the flame sensor. Three strings are for RS485 serial connection physical platform. Mod Bus protocol is used for making connection in RS485 physical platform. In order to minimize circuit noise in this string cable, the power supply unit is isolated from the RS485
