Abstract
The utility model discloses a high temperature resistant ultrasonic flow sensor, include piezoceramics piece, sound wedge, backing, compress tightly the piece, measure the lead wire, the piezoceramics piece passes through bonding agent and sound wedge and links to each other, the backing place in on the piezoceramics piece with the crimping of piezoceramics piece for draw forth and measure the lead wire, compress tightly on the piece arranges the backing in, with sound wedge fixed connection. The utility model discloses have fine high temperature resistant and corrosion resisting property, improved ultrasonic sensor's life, it is used for ultrasonic wave flow measurement instrument, can improve flow measurement's the degree of accuracy, stability and reliability.
Description
Technical field
This utility model relates to a kind of ultrasonic flow sensor, a kind of high temperature resistant ultrasonic flow sensor, belongs to sensor technical field.
Background technology
At present, to pipeline fluid flow measurement many employings ultrasonic flow sensor, conventional sound wedge is plastics, the sonac heatproof being made up of plastic acoustic wedge is low, it is bonding to be difficult to, service life is short, and the poor corrosion resistance to industrial liquid, directly affect stability and the reliability of ultrasonic measurement instrument.
Utility model content
This utility model purpose is to provide a kind of high temperature resistant ultrasonic flow sensor.
For solving above-mentioned technical problem, the technical solution adopted in the utility model is:
A kind of high temperature resistant ultrasonic flow sensor, including piezoelectric ceramic piece, sound wedge, backing, compressing member, measurement lead-in wire；Described piezoelectric ceramic piece is connected with sound wedge by bonding agent, and backing is placed on piezoelectric ceramic piece and crimps with piezoelectric ceramic piece, is used for drawing measurement lead-in wire；Described compressing member is placed on backing, is connected with described sound forelock.
Described bonding agent is bonded adhesives.
Described sound wedge is circular.
Using technique scheme, the beneficial effects of the utility model are:
1, this utility model has the most high temperature resistant and decay resistance, improves the service life of ultrasonic sensor；
2, this utility model is used for ultrasonic flowmeter table, it is possible to increase the accuracy of flow measurement, stability and reliability.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Wherein: 1-piezoelectric ceramic piece, 2-bonding agent, 3-sound wedge, 4-backing, 5-compressing member, 6-measure lead-in wire.
Detailed description of the invention
Embodiment:
As it is shown in figure 1, a kind of high temperature resistant ultrasonic flow sensor, including piezoelectric ceramic piece 1, sound wedge 3, backing 4, compressing member 5, measure lead-in wire 6；Described piezoelectric ceramic piece 1 is connected with sound wedge 3 by bonding agent 2, and backing 4 is placed on piezoelectric ceramic piece 1 and crimps with piezoelectric ceramic piece 1, is used for drawing and measures lead-in wire 6；Described compressing member 5 is placed on backing 4, fixes with described sound wedge 3 and is connected.
Described bonding agent 2 is bonded adhesives.
Described sound wedge 3 is circular metal sound wedge.
Owing to have employed metallic sound wedge and high temperature bonding and meeting the backing of acoustical behavior, this ultrasonic flow sensor is made to have high temperature resistant and corrosion resistant measurement performance, improve sensor service life, and improve stability and the reliability of measurement, its heatproof can cross 160 DEG C, acid and alkali resistance for a long time can corrode, improve the measurement performance of flow instrument, mainly accuracy and reliability.
