The Sensit®Gold G2 is designed to detect combustible gases,
oxygen content and toxic gases when so equipped with the
available sensors. Each model of the Sensit®Gold G2 provides
specific detection features based on approved sensor options.
Each Sensit®Gold G2 can be re-configured or upgraded by the
manufacturer for an additional charge should your sensing re-
quirements change.
Sensit Gold G2 configurations include measuring PPM, LEL
and/or % volume of combustible gases, measurement of oxy-
gen, carbon monoxide, and/or hydrogen sulfide gas(es).
Sensit®Gold G2 instruments incorporate an advanced low power
semiconductor sensor to measure combustible gases in the
LEL (Lower Explosive Limit) range and a thermal conductivity
style sensor to measure combustible gases in the percent vol-
ume range. The user may select either methane or propane gas
readings from a user menu depending on the sensing require-
ments.
An automatically backlit display shows all gas concentrations
being measured. LEDs located on the front of the instrument
indicate preset visual warnings of increased gas concentration.
All gases are continuously sampled with the use of an internal
pump. Audible and visual alarms warn the operator of hazardous
conditions being sensed.
The preset alarms are indicated by a red flashing LED, display
indicator and alarm sound. The combustible gas alarm is preset
from 50% LEL (2.5% methane or 1.1% propane).
GENERAL DESCRIPTION
GENERAL DESCRIPTION continued from page 2
When equipped with the optional percent volume sensor, alarms
remain activated up to 17% methane (12% propane). The car-
bon monoxide (CO) alarm is factory preset at 35ppm. The oxy-
gen (O2) alarms are preset at below 19.5% and above 22.5%.
The hydrogen sulfide (H2S) alarm is preset at 10ppm. The hy-
drogen cyanide (HCN) alarm is set to 5ppm
The Sensit®Gold G2 instrument is approved ATEX Zone 1 in-
trinsically safe Ex ib IIB T3 IP54. Consult Sensit Technologies
for certificate details.
