In 1983, Honeywell introduced the first smart pressure transmitter― the ST 3000®. In 1989, Honeywell launched the first all-digital, bi-directional protocol for smart field devices. The ST 3000 Series 900 Remote Seal Transmitters continue to bring proven smart technology to a wide spectrum of pressure measurement applications. For applications in which the transmitter must be mounted remotely from the process, Honeywell offers the remote seal line of gauge, absolute and differential pressure transmitters. Typical applications include level measurement in pressurized vessels in the chemical and hydrocarbon processing industries. A second application is flow measurement for slurries and high viscosity fluids in the chemical industry. Honeywell remote seal transmitters are available with secondary fill fluids for corrosive or high temperature process fluids.
All ST 3000 transmitters can provide a 4-20 mA output, Honeywell Digitally Enhanced (DE) output, HART output or FOUNDATION™ Fieldbus output. When digitally integrated with Honeywell’s Experion® Process Knowledge System, ST 3000 instruments provide a more accurate process variable as well as advanced diagnostics.
Honeywell’s cost-effective ST 3000 S900 transmitters lead the industry in reliability and stability:
