Description
This section describes the components of the hydrogen transmitter. The transmitter is a 4 -
20 mA type detector head. It consists of the hydrogen 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.
