Introduction Gasman
i-module gas sensor
Gasman uses unique plug and play i-module sensor technology. Each sen-
sor unit incorporates its own intelligent processor holding sensor configu-
ration and calibration data. Different sensors can be purchased, and once
inserted, are immediately ready to run. Flammable units are only available
with rechargeable batteries. Plug and play will ease maintenance time and
cost, and the intelligent modular system will remove the need to calibrate
the sensor. Gasman can be reconfigured by purchasing additional pre-
calibrated i-modules from your local supplier.
Reliable, anti-shock mechanics and robust housing
The Gasman housing is built from resilient material, giving it strength and
flexibility to withstand the hardest of working conditions, water and dust
tight to IP65 and IP67, with a non-slip grip. If the unit is dropped, there
will be no disruption of power or function, ensuring reliability and service
for years to come.
Software
The internal software in Gasman has been designed and written in accord-
ance with the requirement of IEC 61508 to ensure quality and integrity
of operation. Gasman has been designed to give a truly reliable personal
gas monitoring system. The internal circuitry includes an independant
watchdog, the software monitors for any malfunction within the unit and
will display an error warning to the user should they occur.
