General

The BW RigRat Local Area Gas Monitor as a transportable equipment, fills the gap between
portable personal detectors and fixed-infrastructure fire and gas systems. Its primary function
is to alert personnel of a gas leak in their proximity, it can provide continuous measurement of
gas concentrations.
The BW RigRat's main use is in temporary zone monitoring, such as repair, fence line, and inert
applications where there is a possibility of a gas release.
The overall dimensions of the BW RigRat are about 396mm x 288mm x 470mm (15.6" x 11.4" x
18.5"), it consists of an enclosure, 2 rechargeable battery packs P/N 500-0165-000 (or 500-
0165-001 for NA certification) as main power, 1 Li-ion rechargeable cell (P/N MS-621T) for
RTC power, 1 LCD display, 4 LED indicators for light alarm, 2 buzzers for the audible alarm, 1
multi-function button, and printed circuit-board assemblies. In addition, it may also be
optionally equipped with a gas-intake pump, up to 6 kinds of wireless modules in 4 wireless
module slots, and up to 5 kinds of sensors in 6 sensor slots.
An AC charger connector is provided to charge battery packs in a non-hazardous area. Refer to
"Specific Conditions of Use" for more information. An IS charger connector is used to connect
through a safety barrier to charge one of the battery packs in hazardous areas, likewise
providing the intrinsically safe power to the product.
The BW RigRat is transportable and does not require grounding (earthing). However, the
circuits and the metal parts of the enclosure can still withstand a 500V dielectric test with a
leakage current no more than 5mA.

Wireless Module Configuration

Depending on the configuration, the BW RigRat may provide GPS, GNSS, Mesh, Wi-Fi,
Bluetooth (BLE), LoRa, and/or NB-IoT wireless communication, the possible configurations are
shown in this table:

●Optional wireless module

Sensor Configuration

The BW RigRat may be configured with a MIPEX NDIR sensor, Dynament NDIR sensor, LEL
sensor, PID sensor, and EC sensor, which are mounted inside the IP-54 BW RigRat enclosure.
These sensors have been separately certified or tested according to IEC 60079. Refer to this
table for more information about these sensors:
