Honeywell’s new SmartLine ST700 and ST800 pressure transmitter lines are replacing the existing ST3000 100 and 900 series.
If you’re using ST3000 100 series transmitters, you’ll be looking at the ST800 for future units. If you’re using the ST3000 900 series, the ST700 will be your better fit.

have been noticing heat issues with these transmitters. As in when the st700 external temp heats up, we’re receiving intermittent bad PV on the DCS…. Has anybody else had these problems?
