Honeywell Flanged Mount Transmitters

In 1983, Honeywell were the first to market ‘smart’ pressure transmitters using microprocessor technology. Over the years the measuring principle, a 3-in-1 piezoresistive sensor with internal temperature compensation, has been developed to perfection and is unprecedented accurate and stable. The successful ST3000 range, with the series 100 and 900, is succeeded by the SmartLine pressure transmitters. The transmitters with process flanges for level measurement are available in three series:

Series

STF800 SmartLine: High-Performance pressure transmitter, advanced options
STF700 SmartLine: The standard pressure transmitter for the process industry
STF700 Basic SmartLine: Economic pressure transmitter, OEM and projects

Each series has models with an underlying membrane (pseudo flange model), a membrane plane with the flange (flush flange) and front diaphragm (extended flange), which meets the inside of the tank wall and may prevent obstructions of the nozzle.
