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.
Throughout this time i have always found protectowire products to be best in class.
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.
The sensor cable is comprised of two steel conductors individually insulated with a heat sensitive polymer.
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.
Description the linear heat detection cable is a continuous heat detector in the form of a cable.
Ap sensing addresses these problems by using a standard fi ber optic cable as a precise distributed heat sensor.
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 proline th digital linear heat sensor cable range employs a 3 5mm 0 138in external diameter single pair two conductors heat sensitive cable as the basis for its market leading overheat fire detection system.
