HONEYWELL VERSATILIS SIGNAL SCOUT
OVERVIEW
Honeywell Versatilis™ Signal Scout™ (HVSS) and Honeywell
Versatilis™ Signal Scout™ - Energy Harvested (HVSS - EH) are smart
methane gas leak detectors that use Microelectronic Spectroscopy
(MES) technology and a patented design to deliver rapid and
accurate methane gas leak detection across a variety of industries
from the oil and gas supply chain to safety applications.
The HVSS comes in two variants:
n
Honeywell Versatilis™ Signal Scout™ (HVSS):
The variant is an intrinsically safe certified assembly. It has a
single source of power, i.e., powered by a non-rechargeable
Li/SOCl2 battery.
n
Honeywell Versatilis™ Signal Scout™ - Energy Harvested (HVSS -
EH):
The variant introduces the addition of Photovoltaic (PV) panels
and Energy Harvester PCB to the already intrinsically safe
certified Honeywell Versatilis™ Signal Scout™ assembly. Thus the
variant supports dual power sources, i.e. PV cells (solar) and
Li/SOCl2 battery.
The variant is equipped with PV cells mounted on a lid which is
specifically designed to efficiently extract the microwatts (µW) to
milliwatts (mW) of power, generated from a variety of DC energy
harvesting. The energy is harvested from high-impedance sources
like photovoltaic (solar) without collapsing the source.
The battery management features of the variant ensure that a
secondary rechargeable battery is not overcharged by this
extracted power, or with a voltage boost, and not depleted beyond
safe limits by a system load. The integrated multiplexer gate
drivers autonomously switch the system load to a backup primary
non-rechargeable battery if the secondary battery voltage falls
below the defined threshold.
