By mid November, United Electric will begin shipping its new One Series hybrid transmitter-switch models that include HART® Communications Protocol. The newly designed product offering includes a transmitter-only model, as well as another model providing a transmitter plus two solid-state relays. Monitoring pressure or temperature in harsh, hazardous and heavy industrial process measurement and control settings is the target application for these loop-powered transmitters. Models will include UL and ATEX approvals for Divisions 1 & 2 (Zones 1 and 2). With the introduction of the One Series, UE is declaring a number of older models obsolete. You can get a listing of the newly obsolete models from your local UE distributor.

The new combination transmitter and switch model provides a HART® 7 loop-powered transmitter, and includes two programmable solid-state relays, an improved backlit LCD display, and a separate IAWTM health status discrete output.The transmitter-only model is a HART® 7 loop-powered transmitter and also features an improved backlit LCD display.

Some operational benefits, quoted directly from United Electric's product announcement documentation:

• With HART® 7 capability, all of the functions available with the two-button keypad are also available via the HART® Communications Protocol. Using a HART®-compatible hand held communicator or a PC with a HART® modem and appropriate asset management software, users have the ability to quickly configure the One Series, including the switching parameters, and save the configuration in their library for cloning additional controls with the same parameters. We believe this is the only Division 1 electronic switch on the market with HART compatibility!
• If the units are connected to a control system with HART® IO allowing bi-directional communication, configuration can be performed remotely, without the need to remove the enclosure cover in a Division 1 (Zone 1) area.
• Using a HART® capable asset management system, the comprehensive diagnostic functions of the One Series can determine the health status 24x7, saving time and money while allowing operators to focus on other critical issues.
• For cybersecurity purposes, the HART® communications can be set to read-only mode that prohibits parameter changes from unauthorized users and creating a potentially dangerous condition.
