heavy duty industrial pressure sensor is actually a common type of accelerometer.

Sapphire pressure sensor theory and application -Strain resistance operates, as semiconductor-silicon and Sapphire sensitive components with unparalleled metrological qualities. Sapphire Department by single crystals insulated body components composition, does not occurred lag, and fatigue and creep variable phenomenon; Sapphire than silicon to strong, hardness more high, worry deformation; Sapphire has pretty great of elastic and insulated qualities (1000 OC inside), so, using silicon-Sapphire manufacturing of semiconductor sensitive elements, on temperature alterations not sensitive, even in higher temperature situations Xia, also has is excellent of perform characteristics; Sapphire of anti-radiation characteristics pretty strong; addition, Silicon-Sapphire semiconductor sensitive elements, no p-n drift, so, Radically simplifies the manufacturing process and improves repeatability, guarantees higher production yield. -Sapphire with Silicon semiconductor sensor fabrication of heavy duty industrial pressure sensor and transmitters, can perform beneath the most adverse operating situations, and high reliability, accuracy is great, and also the minimal temperature error and higher cost functionality. Gauge pressure sensors and transmitters constructed by double diaphragm: measurement of titanium alloy and titanium alloy receiver diaphragm with diaphragm. Printing of Hetero-epitaxial strain sensitive bridge circuit sheet of Sapphire, measuring diaphragm welded titanium alloys. The measured pressure delivered for the receiver diaphragm (receiving the diaphragm with each other with all the measuring diaphragm lever substantial connection among). Beneath the stress, getting diaphragm deformation of titanium alloy, which just after deformation-Sapphire by Silicon sensing element perception, the bridge output will change, alter the amplitude is proportional to the measured stress. Sensor circuit to ensure energy supply for bridge circuit of strain and strain bridge converts unbalanced signals a unified signal output (0-5,4-20mA or 0-5V). Absolute pressure transducers and transmitters, Sapphire flakes, and ceramic base with glass solder is out there in, plays the role of elastic components, converts the measured stress to deformation of strain, so as to achieve the objective of pressure measurement. Principle and application of piezoelectric high temperature pressure sensor Piezoelectric sensor utilizing Piezoelectric components involve quartz, potassium sodium tartrate and monobasic amine. Quartz (silicon dioxide) is often a organic Crystal, piezoelectric effect is located in which, inside particular temperature ranges, piezoelectric properties has constantly existed, but temperature exceeds this variety, piezoelectric properties disappear totally (this temperature is called the "Curie point"). Because of modifications in stress field transform minor (also stated low piezoelectric coefficients), steadily becoming replaced by other piezoelectric Crystal Quartz. Potassium sodium tartrate has wonderful sensitivity and piezoelectric piezoelectric coefficients, but it is only at space temperature and decrease humidity environment below which it can be applied. Dihydrogen phosphate, is part of an artificial lens, can withstand higher temperatures and high humidity, so it has a wide variety of applications. Piezoelectric effect could be the principal working principle of piezoelectric transducers, Piezoelectric sensor cannot be utilized for static measurements, for the reason that just after the external force, the electric charge, unless the loop with infinite input impedance it really is saved. The actual predicament just isn't like this, so it could only figure out the Piezoelectric sensor for measuring dynamic stress.

It features a easy structure, small size, light weight, extended life and other traits of exceptional. Piezoelectric acceleration sensors in aircraft, automobiles, ships, bridges and buildings within the measurement of vibrations and shocks happen to be broadly used, particularly in the field of aviation and Aerospace has its unique status. Piezoelectric sensors can also be employed to measure internal engine combustion stress measurement and measurement on the vacuum. www.sendosensors.com
