Description
1.Description
   PDS484 remote type absolute pressure transmitter (flat diaphragm type) is used to measure liquid, pressure of gas or steam, then transform them into 4~20mA d.c (with Hart protocol) or PROFIBUS-PA output signal. At the same time can be achieved remote setting, monitoring, and other functions via communication equipment.
