Question 1

miniature pressure transducer

Accepted Answer

The micro pressure sensor with a nominal size of 3mm in outer diameter is specially designed for the measurement of dynamic pressure distribution in aerodynamic research and test, which requires small installation size, does not disturb the flow field, and has excellent dynamic response.

It is used in the measurement of aerodynamic performance such as engine intake port pressure distortion, surge, etc. The natural frequency of the sensitive element is >200kHz.

The pressure sensitive element of the miniature pressure sensor adopts the most advanced MEMS (Miro Electronic Mechanical Systems) technology to design and manufacture.

The three-dimensional integrated, double-sided processed silicon piezoresistive pressure sensitive element has excellent linearity accuracy, and the high uniformity of the Wheatstone strain bridge fabricated by ion implantation and fine lithography makes it have a small temperature drift. The force-sensitive structure of silicon thin film formed by bulk micromachining and precise anisotropic etching enables it to have high pressure sensitivity and radial dimensions as small as 1.5mm.

The advanced miniaturized pressure-sensitive chip adopts stress-free packaging technology, hermetically packaged in a special micro-mounting base and stainless steel capillary.

The reference pressure chamber of the absolute pressure sensor is a vacuum chamber sealed on the back of the chip. The reference pressure chamber of the gauge pressure sensor is led out from the back through a thinner stainless steel capillary to communicate with the atmosphere. In order to facilitate the user to obtain a stable pressure reference, a thin nylon tube is used to lead it to the air pressure stable place.

Question 2

flat pressure sensor

Accepted Answer

Flat pressure sensor may actually refer to a flat diaphragm pressure sensor, or a flat weighing load cell.

Question 3

low cost pressure sensor

Accepted Answer

Low cost pressure sensor. At present, ceramic pressure sensors are the ones that can effectively reduce the cost of industrial pressure sensors.

Ceramic pressure sensor is a pressure sensor refined from a thick ceramic base using a refined ceramic base.

SI-338 Ceramic pressure sensor uses ceramic or diffused silicon core. All stainless steel package, small and beautiful appearance. Suitable for occasions with limited installation space. Wide range temperature compensation, high accuracy, small size, no adjustment, wide range coverage. Support OEM processing. Ceramic pressure transmitter is used in compressor, air conditioning and other pressure measurement.
