Honeywell STG900 Gauge Pressure Transmitter

The Honeywell STG900 is an industrial pressure transmitter from the established Honeywell ST3000 transmitter family.  The Honeywell ST3000 was the industries first “smart” pressure transmitter design, incorporating the popular Honeywell DE communication protocol.  The Honeywell STG900 gauge pressure transmitter is an economical version of the Honeywell STG100 series transmitter, with a slightly increased uncertainty spec but the same rugged industrial design and choice of materials.


This product line is discontinued but has been replaced with the Honeywell STG700 Pressure Transmitter range.
