10. Temperature Output Calculations

To calculate Temperature by measuring the current or voltage output use the following formulas.

For Current output in ºC (-20 to 75ºC)

ºC = (Output measured in miliamps – 4) ÷ .1684 - 20 = ºC

EXAMPLE:(12.0 mA – 4) ÷ .1684 - 20 = 27.5ºC

For Current output ºF (-4 to 167ºF)

ºF = (Output measured in miliamps – 4) ÷ .0935 - 4 = ºF

EXAMPLE:(12.0 mA – 4) ÷ .0935 - 4 = 81.6ºF

For Voltage output in ºC (-20 to 75ºC)

ºC = (Output measured in volts ÷ .010526) - 20 = ºC

EXAMPLE:(0.50 Vdc ÷ .010526) - 20 = 27.5ºC

For Voltage output ºF (-4 to 167ºF)

ºF = (Output measured in volts ÷ .005848) - 4 = ºF

EXAMPLE: (0.50 Vdc ÷ .005848) - 4 = 81.5ºF
