Bell Internal JB

The Fathom Systems bell internal junction box forms an important part of the SAT DMS hardware.

This compact stainless steel unit hosts a number of instruments as well as the bell electrical penetrator used to carry the signals from the sensors inside the diving Bell to the external iAU.  This unit may be supplied with Souriau Jupiter style electrical connectors or glanded entries for hosting cables to the likes of diver’s depth transducers, as well as accommodating  a temperature sensor interface module that converts the bell internal temperature probe signal to a compatible current-loop type. An internal O2 fuel cell also features with a partial pressure (bar) display.
