FTM94/95 Hot wire thermal air velocity transmitter working at a constant Temp. using King's law heat balance equation for:
|
e2=a'+b'vn |
e： |
Sensor voltage output(V) |
|
a'： |
Zero output of constant temperature hot wire anemometer, can use CTA circuit as temperature compensation |
|
|
b'： |
Sensitivity of the sensor, related to the operating temperature |
|
|
v： |
Fluid flow rate |
|
|
n： |
0.45 ... 0.5(Standard) |
Can be calculated from the formula characteristic curve of constant Temp. hot wire anemometer, special double PT probe and full metal housing design, high accuracy, suitable for a variety of pipe diameters, widely used in industrial fields.
