Quartz Endcap And Coated AT Blank For Thickness-Shear Mode Pressure Sensor
The dual-mode Thickness-Shear Pressure sensors is used in the oil and gas industry. It measures both pressure and temperature and provides increased resolution over previous designs. Range and sensitivity for quartz pressure sensor designs are determined by the resonator and endcap dimensions and crystallographic orientation. Performance objectives for the design include the ability to withstand repeated cycling to pressures exceeding full scale (5000 psig or 34.474 x lo6 Pa) at maximum temperature. Additional performance objectives for the sensor include accuracy better than &0.025% of full scale pressure, repeatability better than &0.015% of full scale, and resolution better than 0.01 psi (68.95 Pa).
A unique feature of the design is a large sealing area to minimize stresses transmitted through the joint to the resonator. Adjacent to the sealing face, the cylinder wall tapers away from the center of the cylinder bore, reducing the cylinder wall thickness and increasing the inner bore radius. The re-entrant endcap design employs a thicker cylinder wall at the resonator interface to minimize joint stresses and a thinner cylinder wall away from the joint to reduce the endcap stiffness and enhance sensitivity.
FAQs:
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.
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.
