CẢM BIẾN ÁP SUẤT DẠNG CHÊNH ÁP (ÁP SUẤT THẤP) APLISENS MODEL APR-2000ALW/G

Application

The APR-2000ALW/G transmitter is applicable to the measurement of differential pressure of gases. Typical applications include the measurement of blast pressure, chimney draughts or pressure / underpressure in furnace chambers. The ability to select the radical conversion characteristics enables the transmitter to be used in gas-flow measurement systems using reducing pipes or other impeding elements. The transmitter can withstand overpressure up to 1 bar. The housing of the electronic circuit has the degree of protection IP66/IP67.
