Linear Heat Sensing Cable Working Principle

Linear heat detection lhd also known as linear detection wire or linear heat detection cable or linear heat is a very commonly used method of fire detection it can detect a fire anywhere along the length of the cable and can be of lengths in excess of a kilometer. Description protectowire linear heat detector the main component of our linear heat detection systems is a proprietary cable that detects heat conditions anywhere along its length. Linear heat detectors by protectowire can best be described as a continuous run of spot heat detectors within a versatile cable.

Linear heat sensing cable working principle.

Linear heat cable versatile economical heat detection. Overview fyreline linear heat detection provides early warning of fire or overheating equipment. We are leading supplier and service provider of linear heat sensing cable system. Linear heat detection sensor cable nkt photonics provides the appropriate sensor cable for every application and when working with us we will help you pinpoint the exact cable design and installation appropriate for your project.

Linear heat detection lhd cable is essentially a two core cable terminated by an end of line resistor resistance varies with application. The two cores are separated by a polymer plastic that is designed to melt at a specific temperature commonly 68 c for building applications and without which causes the two cores to short. Designed for use in a wide variety of indoor and outdoor applications lhd fire alarm cables are particularly suited for areas where installation or maintenance access is in a physically demanding or hazardous. A switching cable where a change in state of internal insulation caused by temperature rise to a pre defined level allows a short circuit or hot junction to occur between two twisted tin plated copper.

Applications can range from building fire alarm systems to mobile plant machinery. Linear heat detection is highly cost effective and can be easily installed with or in place of conventional heat detectors where traditional style. System sensor linear heat sensing cable has two different variants digital lhs cable and analogue lhs cable.
