Honeywell STD720 Transmitter

Core Performance & Industrial Application

The Honeywell STD720-e1hs is a SmartLine STD700 differential pressure transmitter, URL ±400 inH2O (±1000 mbar), minimum span 4 inH2O.

Standard accuracy ±0.05% of span (±0.04% high-accuracy option); automatic static-pressure and temperature compensation; rangeability 100:1; response as fast as 100 ms.

HART 4-20 mA output; supply 10.8-42.4 VDC; polarity-insensitive wiring; integral dual-seal per ANSI/ISA 12.27.0; SIL2/3 certified.

It measures DP for flow, level and filter-differential loops as spare replacement on installed SmartLine systems.
