Technical Field
The utility model belongs to the technical field of the pressure transmitter technique and specifically relates to indicate a high accuracy pressure transmitter.
Background
A pressure transmitter is a device that converts pressure into a pneumatic signal or an electric signal for control and remote transmission. It can convert the physical pressure parameters sensed by the load cell sensor into standard electric signals for the secondary instruments such as indicating alarm, recorder and regulator to measure, indicate and regulate the process. However, due to the unreasonable structural design, the existing pressure transmitter has low detection precision and detection data are not accurate enough.
SUMMERY OF THE UTILITY MODEL
In view of this, the present invention is directed to the deficiency of the prior art, and the main objective of the present invention is to provide a high-precision pressure transmitter, which has a function of detecting pressure with high precision.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
a high-precision pressure transmitter comprises a pressure transmitter body; the pressure transmitter body is provided with a supporting cylinder, the end part of the supporting cylinder is provided with a detection head, the end face of the detection head is provided with a corrugated diaphragm for detecting pressure, the corrugated diaphragm is located in the middle of the end face of the detection head and protrudes outwards, and the ratio of the area of the corrugated diaphragm to the area of the end face of the detection head is 0.08-1.2.
Preferably, the outward protruding distance of the corrugated membrane is 2.5-3.5 mm.
Preferably, a sealing ring is sleeved on the peripheral side of the corrugated diaphragm.
Preferably, the diameter of the supporting cylinder is 35-37 mm.
Preferably, the diameter of the detection head is 198-202 mm.
Compared with the prior art, the utility model obvious advantage has and beneficial effect, particularly, can know by above-mentioned technical scheme, it is mainly through the area with the ripple diaphragm with the area of detection head end face design for 1:10 to increased the detection area of ripple diaphragm, improved pressure transmitter's detection precision, and, because the ripple diaphragm is outside protruding, can ensure like this that pressure transmitter aligns with the installation position correctly, avoid the installation to appear the deviation, further improved pressure transmitter's detection precision.
To illustrate the structural features and functions of the present invention more clearly, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
