DP800 Industrial Grade Pressure Difference Transmitter
DP800 is an industrial-grade pressure difference transmitter based on diffused silicon technology, with high precision and good stability. It is widely used for measuring pressure difference parameters of gas or liquid medium in HVAC, biopharmaceutical, vessel and other industries. The user can choose the output signal according to the need: 4~20mA or 4~20mA+HART protocol. DP800 has a minimum pressure measurement range of 0~1KPa and a maximum of 0~6MPa. It can measure a variety of non-corrosive, non-hazardous gas and liquid medium.
