Product Description

Thickness Shear Mode Quartz Resonator Sensors For Temperature And Pressure

 

A quartz pressure sensor for downhole oilfield applications consists of a quartz piezoelectric resonator hermetically sealed between two quartz end caps. The resonatorand endcaps are made of quartz which is AT cut. An AT cut is preferred because it has the smallest temperature response compared to other available cuts. The quartz resonator is AT cut biconvex thickness shear mode. BonTek is capable of fabricating with high quality both the end caps and the quartz resonators.

 

Pressure applied to the external surfaces of the sensor forces the cylinder bore walls to displace inward. Planar compressive stresses are generated in the resonator in response to the cylinder displacement. An oscillator circuit maintains resonant vibration of the sensor resonator. The resonant frequency changes in direct proportion to stresses induced in the resonator by the external pressure [3]-[5]. The oscillator outputs a signal with a frequency that is directly proportional to the pressure. An electronic counter transforms the number of counts generated by the sensor signal in a given gatetime to a digital frequency.

FAQs:

 

  1. Q: What are the products you mainly work on?

A: We look at ourselves as the piezo wafer specialist. We are the very first to work with Single Crystal Quartz in China about 30 years ago. Then gradually we step in the field of LiNbO3, LiTaO3, Quartz glass, LGS, CTGS etc. Especially, if you are looking for a piezo quartz supplier, we are the ultimate choice! We export millions of quartz blanks each year because we master the AT, SC and IT cuts with superior angle precision.

 

  1. Q: Can you accept product customization?

A: Yes, of course. We can fabricate as per your request. In addition, we are so experienced with piezo wafers that we can provide you relevant suggestions if you are not 100% sure about your choice. Besides, we do have some standard wafers in stock, please check with us.
