Linear heat sensing cable pdf.

The insulated conductors are twisted together to impose a spring pressure. Protectowire linear heat detector is a proprietary cable that detects heat conditions anywhere along its length. 68ºc 78ºc 88ºc and 105ºc. Out of kenilworth new jersey installed a fiber optic linear heat detection system for railroad platform protection in north america s busiest train station five years ago.

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. Of twisted pair tri metallic conductors sheathed in new advanced thermal polymers. My company united fire protection corp. Ap sensing addresses these problems by using a standard fi ber optic cable as a precise distributed heat sensor.

Description the linear heat detection cable is a continuous heat detector in the form of a cable. Digital linear heat sensing cables system sensor fixed temperature linear heat detection cable range consists of a twisted pair of extremely low resistance 05 ohm ft. System sensor 800 series digital linear heat detector and 900 series analogue linear heat detector offer early detection of fire and overheating conditions in industrial high risk hazards as well as many types of commercial applications. Applications can range from building fire alarm systems to mobile plant machinery.

Applications tunnels metros car parks conveyor belts cable trays and transformers. The sensor cable is comprised of two steel conductors individually insulated with a heat sensitive polymer. Find here linear heat sensing cable digital lhs cable manufacturers suppliers exporters in india. Our linear heat series measures an accurate temperature profi le every few seconds along a fi ber optic cable up to several thousand meters.

This makes lhd linear heat sensor cable to be the most adequate fire detection system for extreme environmental conditions. I have been a protectowire distributor for 25 years. 1 1 temperature ranges and outer extrusion types there are 4 different types of lhd heat sensor cables depending on the alarm temperature chosen. With a range of up to 10 km and a sampling interval down to 25 cm the system is ideal for fire detection in tunnels and metros as well as large facilities like warehouses and industrial facilities.
