Linear Heat Sensing Cable System Sensor

System sensor linear heat sensing cable has two different variants digital lhs cable and analogue lhs cable.

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 lhs system sensor fixed temperature linear heat detection cable range consists of a twisted pair of extremely low resistance 05 ohm ft. The insulated conductors are twisted together to impose a spring pressure. 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.

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. Linear heat detectors by protectowire can best be described as a continuous run of spot heat detectors within a versatile cable. 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. Protectowire linear heat detector is a proprietary cable that detects heat conditions anywhere along its length.

Of twisted pair tri metallic conductors sheathed in new advanced thermal polymers. Linear heat cable versatile economical heat detection. We are leading supplier and service provider of linear heat sensing cable system. The 900 series is an analogue heat sensing cable containing insulators of which resistance varies proportionally to changes in temperature.

Applications can range from building fire alarm systems to mobile plant machinery. 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. Alarm panels via system sensor monitor modules. 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. 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.
