Honeywell SmartLine ST800 Modular Absolute Pressure Smart Transmitters

In the 1980s, Honeywell introduced the world's first smart transmitters. In 2012, they're introducing the latest in smart transmitter technology: a fast-responding, high accuracy, modular transmitter series, designed to improve value across your entire plant lifecycle.

Honeywell SmartLine ST800 transmitters can help you reduce project costs, cut startup and commissioning time, lower total maintenance costs, reduce repair time, enhance safety, lower operating costs, reduce unplanned downtime, and improve product quality.

SmartLine ST800 transmitters are designed to replace older ST3000 Series 100 transmitter models. To replace or upgrade an ST3000 Series 900 model, see the new Honeywell ST700.
