VT110 Clean Industrial Pressure-Difference Wind Speed Transmitter

The monitoring of wind speed and wind volume in air conditioning pipes in clean industries such as biopharmaceuticals and electronic semiconductors can not only ensure the normal operation of the air conditioning system, but also effectively control the operation energy consumption. VT110 is a pressure difference principle-based wind speed transmitter with temperature compensation function, fitted with the average wind speed gauge installed in the air conditioning pipe. 

      At present, similar products based on the principle of single point wind speed measurement have very high requirements for the installation of straight pipe sections. For example, the straight pipe section of air conditioning is too short or the distribution of air fluid is irregular turbulence in the position of elbow pipe and valve accessories, so stable and effective wind speed cannot be measured. Thanks to VT110 average wind speed gauge, the multi-point wind speed in the same section of the air conditioning pipe is collected and averaged, which has relatively low requirements for the straight pipe section and installation position, and can also ensure the accurate measurement of wind speed, so it is very suitable for the complex air conditioning pipe conditions on site.
