IP67 Rugged stainless steel case, fit in variety harsh environment Easy to install, imported sensing element, high accuracy, long-term stability Switch multifunction physical quantities(Air velocity and volume)：[m/s]、[ft/s]、[Nm3/h]、[Nm/s]、[L/min]、[m3/min] LCD Display of air velocity and temperature
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.
