| The Duratran® transmitter introduces a unique electronic pressure-indicating transmitter |
| The Duratran® transmitter introduces a unique electronic pressure-indicating transmitter with direct mechanical indication suitable for aggressive environments and process fluids.
The Duratran transmitter combines outstanding, reliable local indication that functions without the need for external power with a stable, self-contained 4/20mA transmitter in a hermetically sealed corrosion-proof case (Type 2279).
The wide selection of system materials and corrosion-proof housing meets application requirements in a number of industries. These include chemical processing, petrochemical and refining plants, electric and gas utilities, wastewater and other industrial applications.
This electronic pressure-indicating transmitter promises increased service life and long-term stability. |
