Figure 17.3: LED Code on N2 Level Sensor

Interface

The N2 level sensor is connected to the BSMS BSVT electronics (back panel RJ45 connector
labeled NITROGEN LEVEL) and to the CryoPlatform if a BSNL option is installed (Bruker
Smart Nitrogen Liquefier). These units provide the necessary power supply and data
interface signals.
