AMR SENSORS- Mode d'emploi / User guide version V1.2
In the case of an analogue sensor (0-10 V version), the formula is as follows: I = value x 2.048 x 337.3/(220 x 67.3)
Procedure:
• Convert the value of the frame into a decimal: 0 x 063CCE = 408782 as a decimal
• Apply the following formula: I= 408782 x 2.048 x 337.3/(220 x 67.3) =4.001 V)
The result is: 4.001 V
•
If, in our example, our sensor is a temperature sensor that measures a range from -40°C to +80°C, 0 V corresponds to -40°C and 10 V corres-
ponds to +80°C (note: we are working from the principle that the sensor used has a linear response curve).
To convert the value in V into a temperature, you have to apply the following formula: T° =-40 + (V x 120/10) Result: -40 + (4.001 x
120/10) = -8°C
Note:
• V = the value in V
• -40 = the offset to be applied
• 120 = the spread of the temperature range (from -40 to +80)
• 10 = the range of the voltage measurement (from 0 to 10 V)
