Flame And Gas Detectors Use HART Communication Protocol

Detector Electronics Corporation (Det-Tronics) recently announced flame detectors and gas detectors that use the HART communication protocol. The announcement came as Det-Tronics added HART functionality to its X9800, X2200, and X5200 flame detectors. The HART protocol permits digital signals carrying information such as diagnostic parameters and device configuration to be transmitted simultaneously with the 4-20 mA analog signal. Det-Tronics manufactures flame detectors, gas detectors, and safety systems and is part of UTC Fire & Security, a unit of United Technologies Corp. (NYSE:UTX).

The enhancement leads to more efficient device set up because facilities can easily configure and adjust many detector variables to their needs. For example, a device can be given a recognizable name, such as "line1 flame detector." Variables then can be set and adjusted using universal HART commands.

"Workers in the control room or field can configure or change device settings using a variety of tools," says Product Manager Mike Bragg. "They can enter HART commands locally or remotely via our FlexVu Universal Display, a HART communicator, or an asset management system."
