live:.cid.32dc366d67c3df36eYc FTM94/95 Industrial Grade High Accuracy Thermal Mass Flow Transmitter
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：[m/s]、[ft/s]、[Nm3/h]、[Nm/s]、[L/min](Air velocity and volume)
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.
