PRESSURE SENSOR CONVERSION CHART (Bench Calibration)
Examples of “Bench Calibration” Calculations
TFT32 Tank Farm Transmitter
Manual Series 2.4
Page 14
Example 1
-
PS11
sensor
- Specific gravity of tank contents is
1.5
- Sensor is mounted at a level of
6 inches
- Calibration units (
CALU
) are in
inches
LO = 6.0
[20mA Level] = 138.6 inches
HI
= [20mA Level] +
LO
= 138.6 + 6.0 =
98.4
Specific Gravity
1.5
Example 2
-
PS11
sensor
-
Specific gravity of tank contents is
1.0
- Sensor is mounted at a level of
15
cm
- Calibration units (
CALU
) are in
cm
LO = 15.0
[20mA Level] = 352.0 cm
HI
= [20mA Level] +
LO
= 352.0 + 15.0 =
367.0
Specific Gravity
1.0
