FIELD: electricity. ^ SUBSTANCE: field device (200) of production process has housing (202) with wall (204). Wall has feedthrough hole (207) between battery compartment (208) and compartment (206) of electronics. Feedthrough connector (230) seals the feedthrough hole and includes power connector (234, 236) connected to electronics (212) of field device of production process. Feedthrough connector includes polarisation cover which envelopes power contacts available from battery compartment for connection. Battery assembly (216) includes battery housing with connector (244) of battery, which includes poured base of connector, which protrudes into polarisation cover, and electric contacts which come into contact with power contacts in polarisation cover, and includes battery (242) and power limiter (240) connected to battery connector which is engaged with power connector for supply of power to electronics of field device of production process. Seal (250) seals the connection of polarisation cover and base of connector. ^ EFFECT: increasing operating safety in environments including combustible atmospheres and corrosion chemicals, and in vibration conditions. ^ 11 cl, 8 dwg |
