Description
This section describes the components of the combustible gas transmitter. The transmitter
is a 4 - 20 mA type detector head. It consists of the combustible gas detector, calibration
cup/splash guard, amplifier, the amplifier junction box, and the detector junction box.
The two junction box configuration is intended for situations where the detector needs to
be installed at an inaccessible location. The detector junction box can be installed at the
inaccessible location and the amplifier junction box can be installed in a more readily
accessible area.
