  • Assemblies, circuits, and methods of transmitters between different equipment protection levels in a hazardous environment
    Patent number: 12345560
    Abstract: The disclosure relates to a transmitter assembly for a hazardous environment. The transmitter assembly includes a transmitter that includes a transmitting unit and a probe. The transmitting unit is configured to be positioned in a first area and includes an intrinsically safe circuit. The probe is configured to be positioned in a second area that is more hazardous and has a higher equipment protection level than the first area. The probe is electrically connected directly or indirectly to the intrinsically safe circuit. The transmitter assembly also includes a separation assembly positioned between the transmitting unit and the probe and including a hermetic seal configured to be electrically connected to the transmitting unit and the probe and a nut defining a tunnel sized to receive the hermetic seal therein. The exterior threads of the nut are complementary to threads on a partition wall positioned between the transmitting unit and the probe.
