Description


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.
