Description
Technical field
The present invention relates to a kind of pressure gauge, be specifically related to a kind of mud special pressure transmitter.
Background technology
Current pressure transmitter is commonplace, but becomes for the pressure under the slurry environment such as oil field, strong motion, humidity
Sending device little, if with the pressure of usual pressure transmitter measurement mud, mud easily blocks tracting pressuring hole, and spoilage is the highest, need through
Often maintenance, adds operating cost, reduces production efficiency.
Summary of the invention
For solving in oil drilling, well logging, mud easily blocks tracting pressuring hole, and adapts to the adverse circumstances such as strong motion, humidity, this
Invention provides a kind of mud special pressure transmitter.
The present invention adopts the following technical scheme that
A kind of mud special pressure transmitter, including sensor base, is provided with sensor, sensor base in sensor base
Seat one end connects end cap, and one end is provided with tracting pressuring hole, is provided with sealing locating piece at tracting pressuring hole, seals and sets between locating piece and sensor
There is pilot dielectric cavity, in pilot dielectric cavity, be provided with silicone oil, seal between locating piece and sensor using silicone oil as pilot medium, fall
Low-pressure is lost.
Sensor connection line plate, wiring board connects binding post, and wiring board and binding post are arranged in end cap.
One end of described end cap is provided with watchcase.
In order to ensure use safety, end cap be respectively provided on two sides with anti-explosion cable introducing device and explosion-proof screw plug.
Described sensor base arranges one end of tracting pressuring hole and is provided with external screw thread, is connected to the spiral shell of measure field by external screw thread
On stricture of vagina joint.
Advantages of the present invention and having the beneficial effect that
The present invention, on the basis of usual pressure transmitter, increases tracting pressuring hole, installs sealing additional in measuring pressure of sensor position
Locating piece, seals using silicone oil as pilot medium between locating piece and sensor, seal locating piece can effectively prevent mud with
The damage to sensor of the granules such as grit, plays the effect of anti-scratch, improves service life.
Sensing element of the present invention design is succinct, precision high, volume is little, can at drilling well, the pressure of surveying borehole measurement mud,
And the application in oil field at home has obtained the highest evaluation.
