| |
Detecting the visible light in the boiler and gives current sigal to the flame scanner amplifier in the control room |
|
|
| |
Used for mounting the flame scanner assembly inside the boiler |
|
 |
| |
Convers the light intesity in to current signal |
|
 |
| |
INPUT : 85 TO 230 V AC
OUTPUT : + 15 V DC & - 15 VDC
Fold back current limited & short circuit current protected |
|
 |
| |
The received current signal from the housing electronics module is further processed and sent to frequeny card and lamp & meter card.the malfunction of housing electronics module is also detected. |
|
 |
| |
The frequency signal from the intensity card is further processed to get the indication of frequnecy of flame in side the boiler.this will discriminate the oil flame & coal flame.two frequency card is used in safe flame scanner-ii for detecting the oil flame and coal flame. |
|
 |
| |
It provides a contact closure when atleats 2/4 scanners detecting fire ball flame.It also provides a contact closure when a fault is detected on any scanner cable or scanner head electronics |
|
 |
| |
This card will indicate the visualflame intensity/fault and flame/no flame condition of oil gun flame. |
|
 |
| |
This will indicate fireball flame/no Flame condition. |
|
| |
| |
This will send the current signal and supply voltge to the flame scanner assembly from the flame scanner amplifier in the control room available nearest junction box. |
|
 |
| |
This will protect the housing electronics |
