ABB 266DRHFSSB2S3 Differential Pressure Transmitter

Feature & Principle

It is ABB 266DRH series capillary remote seal intelligent differential pressure transmitter. It adopts capacitive sensing element, matched with fully welded remote diaphragm seal and capillary filled with transmission fluid. The diaphragm isolates high-temperature, viscous or corrosive process medium to protect the sensor core. The pressure signal is transmitted to the sensing module through filling liquid, converted into 4-20mA analog plus HART digital signal. It supports TTG through-glass local operation without opening cover, built-in pipeline blockage diagnosis, plug-and-play electronic assembly for convenient on-site replacement.
