A Heat sensing cable is a cable that detects heat. There are different types of linear heat detection cable and the terminology used by end users, specifiers and manufacturers varies. So what do we mean by ‘digital’ or ‘analogue’ or ‘Fixed Temperature’ and why do our Signaline HEAT Sensing Cables use the terms ‘Fixed Temperature’ and ‘Analogue’?
Linear heat sensing, linear heat detecting, and linear temperature sensing cable are general broad based descriptions of linear heat detection cable. They do not describe exactly what type of linear heat detection cable is required.
Digital, Analogue and Fixed Temperature are terms used to describe a particular type of linear heat detection cable.
Digital and Fixed Temperature mean the same thing. Both terms are used to describe linear heat detection cables that go into alarm at a pre-determined temperature.
Digital was the original generic description used for linear heat detection cables that go into alarm at a pre-determined temperature. ‘Digital’ is a description that is still often used today. However these days ‘digital’ is widely used to describe all manner of consumer and industrial electronic technologies from iPads, mobile phones, computers to industrial process control protocols and data networks. To apply the term ‘digital’ to a linear heat detection cable that contains no electronics whatsoever has become misleading.
Fixed Temperature precisely describes a linear heat detection cable that goes into alarm at a pre-determined temperature. The term ‘Fixed temperature’ accurately describes a particular type of cable which is why we use it for our Signaline FT cables.
Analogue is a generic term used to describe a linear heat detection cable that changes its electrical characteristics when heated. The changes in the cable are monitored by a dedicated controller. Our Signaline HD series of cables are ‘Analogue’ linear heat detection cables.
