Description

Technical Field

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

[0002] The differential pressure transmitter is also called the differential pressure transmitter. Its basic principle is to divide a space into two chambers with a sensitive element (multi-purpose diaphragm box). When pressure is introduced into the two chambers respectively, the sensor produces displacement (or displacement trend) under the combined action of the two pressures. The displacement is proportional to the pressure difference (differential pressure) between the two chambers. This displacement is converted into a standard signal output that can reflect the size of the differential pressure.

[0003] The existing differential pressure transmitter has a connecting pipe that is directly connected to the differential pressure transmitter body, which is easily dislodged when subjected to external collision, thereby affecting its normal use. Summary of the invention
