6 HARDWARE OVERVIEW
The GASMAX/TX is a self-contained, battery-operated single or dual channel gas detector with local or
remote sensors. The unit consists of an explosion proof enclosure, sensor head (if utilizing a local sensor),
antenna tuned for either 900 MHz or 2.4 GHz frequency bands, a display module with microprocessor and
radio and I/O battery board that doubles as mounting hardware for the display. The display attaches to
the I/O battery board via a short multi-pin cable and two captive thumbscrews.
Figure 6-1: GASMAX/TX with Single Local Sensor
The GASMAX/TX wireless gas monitor is capable of monitoring two separate sensors. In certain cases, it is
appropriate to co-locate both sensors in a ‘local sensor’ configuration. When doing so, the GASMAX/TX is
configured with a Y-adapter that supports two independent electrochemical or infrared sensors (See Fig.
5-2).
