FAQ
What is titanium/silicon – sapphire pressure sensor?
The superior elastic properties of the sapphire substrate provide the perfect platform, pressure sensor based on the platform have excellent repeatability, no measurable hysteresis and. Its measurement sensitive element consists of a silicon piezoresistive strain gauge microcircuit. The single crystal silicon forms a strong molecular bond with the sapphire substrate, through a high temperature diffusion process, the sapphire substrate is connected with a solid titanium alloy pressure diaphragm. The excellent insulating properties of sapphire allow the sensor to operate over a very wide temperature range without loss of performance. Combined with all titanium wetted parts, this sensor offers unparalleled performance with high overpressure and good chemical compatibility.
What application silicon on sapphire pressure sensor?
Since the sapphire has excellent properties in chemical stability, corrosion resistance, radiation resistance etc., the pressure transmitters with silicon on sapphire pressure sensor are widely used in the industries of aerospace, ship, automobile, petroleum.
What characteristics should you look for in a pressure transmitter?
With a lot of pressure transmitters, and sometimes it may be difficult for you to understand the specifications of these products. Generally, In order to achieve the desired results, it is necessary to consider the following items, transient maximum pressure, measuring range, temperature, corrosive, response speed, stability and accuracy.
