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.
