Autronica Gas Detection

China [CN]

In the demanding environments of the petrochemical oil and gas industry, fire and gas detection has to deliver optimal results at all times. Autronica gas detection offers traditional detectors with 4-20 mA and/or relay output, but we have also taken the IR point gas detection a step further.

Product Introduction

A key feature of the HC300PL IR gas detector is the built-in PowerLoop system technology, enabling the detector to communicate with AutroSafe Integrated Fire and Gas (IFG) systems on a single pair of wires. This compatibility, called the PowerLoop technology, is a two-wire power and signalling bus connected in a ring topology and galvanically isolated from the rest of the system, saving cable cost and weight. Each detector has a built-in short-circuit isolator, hence no detectors will be lost because of a single break or short-circuit in the PowerLoop lines. All alarms and faults are signalled via the PowerLoop. The Fire and Gas Detection Systems supplier does not require any local power supply.
