Technical Field

[0001] The utility model relates to the field of pressure transmitters, in particular to a split pressure transmitter. Background Art

When the connecting plug 4 is inserted into the pressure transmitter body 101, the connection between the pressure transmitter mechanism 1 and the transmission line mechanism 5 can be reinforced through the set fixing component 6, so as to avoid loose connection. When the fixing component 6 is working, the spring 604 is forced to expand and contract, so as to drive the connecting block 602 and the clamping block 601 to extend or extend into the slot 7, and is fixed by cooperating with the fixing block 9, so as to avoid the transmission line mechanism 5 being set too long and workers accidentally touching the transmission line mechanism 5, causing the transmission line mechanism 5 to loosen and fail to work normally.
