When there are multiples of the same device used in a diagram, this numberhelps viewers to reference that specific instrument.TI01TC01TC02If you were looking at a list of the controls, you could look at the control loop number to find thatspecific device on the P&ID.

OEM Direct Replacement Flame Sensors. What is a Flame Sensor? A Flame Sensor is a probe that is installed in front of a burner where a flame would burn during operation. Electric is applied to the rod from the control board. When the flame comes on and contacts the rod a DC micro-amp signal is sent back to the control board.

2. Flame-retardant Tape Flame-retardant tape is made of material which has advanced self-extinguishing properties, making it highly resistnat to flame. When subjected to strong flame, the rate of combustion is lower and spread of the burn slower than in the case of ordinary tape. UL Flame test UL 510(FR) UL 94 Title Insulating tape (FR: Flame .
