Honeywell Flanged Mount Transmitters
In 1983, Honeywell introduced the first ‘Smart’ pressure transmitters based on advanced microprocessor technology. This groundbreaking technology utilizes a 3-in-1 piezo-resistive sensor with internal temperature compensation, which has since been refined to deliver unparalleled accuracy and stability. The successful ST3000 series has evolved into the innovative SmartLine pressure transmitters, including models specifically designed for level measurement with process flanges.
SmartLine Series Flanged Pressure Transmitters
Honeywell offers a comprehensive range of flanged pressure transmitters tailored to meet the specific requirements of level measurement in industrial processes:
- STF800 SmartLine: A high-performance pressure transmitter with advanced options, ideal for demanding applications.
- STF700 SmartLine: The standard choice for reliable level measurement in the process industry.
- STF700 Basic SmartLine: A cost-effective pressure transmitter, perfect for OEM projects and budget-focused applications.
Design options for specific applications
Each series provides various configurations to meet diverse process needs:
- Pseudo Flange Model: With a recessed diaphragm for standard applications.
- Flush Flange Model: Featuring a diaphragm flush with the flange for easy cleaning and minimal buildup.
- Extended Flange Model: With a protruding diaphragm aligned with the tank wall, ideal for preventing nozzle blockage.
