LST Digital Linear Heat Detection

Product Overview

Tried and tested linear overheat detection.

The Ampac Linear Sensing Technology LST, is a range of digital linear heat detection cables and is designed to trigger a response when a specific temperature is reached. If the temperature surrounding the cable reaches the activation temperature the two cores quickly come into contact and trigger an alarm. These cables are known as ‘digital’ because they are ‘off’ below the activation temperature and irreversibly switch ‘on’ when the activation temperature is reached.

The technology uses a twisted pair of low resistance, tri-metallic conductors, sheathed in advanced temperature sensitive polymers.
