4.7 AutroPoint Gas Detector HC300 PL
The AutroPoint HC300 PL is a diffusion-based, infrared combustible
gas detector that provides continuous, fixed monitoring of flammable
hydrocarbon gases in concentrations from 0 to 100% Lower Explosive
Limit (LEL).
Ideally suited for protection of challenging on/offshore oil and gas
facilities and other downstream hydrocarbon applications, the
AutroPoint HC300 PL is certified for use in hazardous areas Zone 1
and Zone 2. In addition, the stainless steel construction, sapphire
optics, and modular design all combine to deliver industrial grade
hardness along with easy installation and the lowest cost of ownership
available.
The AutroPoint HC300 PL is capable of detecting hundreds of
flammable hydrocarbon vapours. Field-selectable algorithms are
provided for methane (default), ethane, propane, butane, ethylene,
and propylene. Numerous additional operating parameters are
programmable via an optional hand-held communicator.
The detector has a built-in PowerLoop technology which allows the
detector to be powered and communicate with AutroSafe Integrated
Fire and Gas panels (IFG) on the same pair wire, 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, like dirty optics and temperature out of range,
will be signalled via the PowerLoop.
The PowerLoop is a two-wire power and signalling bus connected in a
ring topology and galvanically isolated from the rest of the system.
The detector does not require any local power supply.
• See handbook for detector HC300 PL regarding calibration and
additional information.
