1. General Introduction
Rosemount 2088 Pressure Transmitters is a light weight compact design and economical type for gauge and absolute pressure measurement, it only supports 4–20 mA HART and 1 to 5 Vdc HART Low Power output, stainless steel or Alloy C-276 wetted materials. There is a configurable LCD display to display process variable, percent of range, and diagnostic messages, also supports to mount with manifolds and remote seals .
