Typical Applications
The Honeywell STR800 series with remote diaphragm seals is engineered for critical process control where the transmitter electronics must be isolated from the process media. Typical applications include:
•High-Temperature Processes: Where direct-mount transmitters would exceed thermal limits.
•Viscous or Suspended Solids: Preventing clogging of impulse lines in heavy chemical or pulp & paper applications.
•Corrosive Environments: Utilizing specialized diaphragm materials to resist aggressive chemicals.
•Level Measurement: Highly accurate level measurement in pressurized vessels (hydrocarbon processing, refining).
