CHAPTER 3 - OPERATION

FLUID COMPONENTS INTL

Converting Temp Out Voltage to Temp in Degrees F

This formula is useful when monitoring the temperature output voltage with a data acquisition system where the
formula can be used in the program.

Use the following formula to determine what the temperature is in degrees Fahrenheit, if the FLT temperature output
voltage is known.

y = a + bx + c/x + dx

2

+ e/x

2

+ fx

3

+ g/x

3

Where:

y = Temperature in Degrees F

x = FLT Temperature Output Voltage

a = -533.998303

b = 251.-092242

c = 218.4101830

d = -1.25664666

e = -225.492653

f = 0.522817769

g = 95.41271936
