3.1 MECHANICAL
The maximum operating temperature for the flame sensor is 302° F (150° C).
temperature at the location of the sensor exceeds this then cooling will be required. There are two methods
available for cooling: air-cooling with ambient air, and air-cooling with pressurized air.
Air-cooling with ambient air can be used in installations where the enclosure is cooled with forced air. This
would be typical of LM2500 and LM6000 aircraft engine applications. The air velocity at the sensor must be 5
ft./sec (1.5 m/sec), or greater, at a temperature of 50° F (10° C), or less, above outside ambient. Under these
conditions the sensors will operate at outside ambient temperatures up to 140° F (60° C).
Air cooling with pressurized air requires the use of Air Cooling Can BHGE Reuter-Stokes Part Number RS-
E2-0259 (GE Part Number 07482SOCNL44821P01). The Air-Cooing Can is installed as shown in the following
drawing. The Air-Cooling Can requires 25 psi (170 kPa) minimum at 120° F (49° C) maximum. Under these
conditions the sensors will operate at ambient temperatures up to 302° F (150° C)

INSTRUCTIONS" on the next page. Leave the sensors installed hand tight until after the sensor checkout
described in Section 3.3.
