Temperature Sensor
The PDA system utilizes a thermal sensitive, fuel temperature sensor that is connected to the
TIM via an intrinsically safe barrier. The PDA system records temperature compensated
fuel to 60 degrees Fahrenheit (15 degrees Celsius) and requires no fuel system component
intrusion for installation.
Figure 16 – Thermal Temperature Sensor
The temperature sensor’s flat bottom surface should be attached to a clean metallic surface
on an input or output plenum as close to the refueling equipment’s fuel meter as possible.
The sensor should be securely wrapped with Scotch brand Electrical Moisture Sealant tape
D.C.I. # 06147 and secured with two 16-inch zip ties.
