Af400b high temperature resistant and anti blocking type wind speed (air volume) transmitter
I. overview
Af400b transmitter with standard S-type pitot tube can measure the flow and velocity of high temperature flue gas
2, Functional features
1 stainless steel pitot tube temperature resistance (450 ℃), standard transmitter host: LCD display, zero adjustable on site, full adjustable on site.
2. Good stability, long-term stability of fullness and zero position up to 1% FS / year. The temperature drift of the main engine is less than 1% FS in the range of 0 ~ 70 ℃, and less than 1% FS in the whole allowable working temperature range.
3. It has reverse protection and current limiting protection circuit. When the positive and negative poles are connected reversely during installation, the transmitter will not be damaged. In case of abnormality, the transmitter will automatically limit the current within 35mA.
4 solid state structure, no movable parts, high reliability, long service life.
5. It is easy to install, simple in structure, economical and durable.
