Linear Heat Sensing Cable System Sensor

Description the linear heat detection cable lhdc is a continuous heat detector in the form of a cable.

Linear heat sensing cable system sensor.

The 900 series is an analogue heat sensing cable containing insulators of which resistance varies proportionally to changes in temperature. System sensor linear heat sensing cable has two different variants digital lhs cable and analogue lhs cable. We are leading supplier and service provider of linear heat sensing cable system. 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.

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. 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 sensing cable lhs system sensor fixed temperature linear heat detection cable range consists of a twisted pair of extremely low resistance 05 ohm ft.

Of twisted pair tri metallic conductors sheathed in new advanced thermal polymers. 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. Linear heat cable versatile economical heat detection. Alarm panels via system sensor monitor modules.

The lhs linear heat sensor is designed for open area as well as proximity detection. The sensor is completely passive over its entire detection range and the de tect fiber optic linear heat detection can therefore be carried out in areas where high safety risks exist even in areas with a risk of explosion. The sensor cable consists of a twisted pair of 19 awg copper coated steel conductors covered by a temperature sensitive insulation and protected by either a plastic braid or jacket for various environmental applications. Protectowire linear heat detector is a proprietary cable that detects heat conditions anywhere along its length.

The sensor cable is comprised of two steel conductors individually insulated with a heat sensitive polymer. Linear heat detectors by protectowire can best be described as a continuous run of spot heat detectors within a versatile cable.
