Some electronic sensors use other properties, such as density, ionization or thermal conductivity, to infer the pressure of a gas rather than measuring it directly. A resonant sensor uses changes in resonant frequency (the frequency at which a gas vibrates most readily) to measure changes in gas density caused by pressure. The sensing element can …
For pressures sensors, if they can’t stand the boiling heat, the freezing cold, corrosive substances, being submerged in salt water, constant exposure to the outside world, they might not be fit for the job. In other applications, corrosive pressure media can present a threat to sensor components such as the diaphragm, or to the integrity …
The things we use, carry and wear on a daily basis are growing in intelligence. More and more, our appliances are able to detect changes in their environment and modify their behaviour based on those changes. Pressure sensors are one of the technologies enabling smarter consumerelectronics. Keeping food fresher for longer with partial vacuum A …
As urban population density increases, larger buildings are becoming increasingly commonplace, and controlling their internal environment accurately is a challenge for designers and operations staff alike. In addition, rising environmental concerns and tightening regulations have made minimizing resources used to heat and cool buildings a serious consideration. The business of building automation integrates heating, ventilation, …

Real-time sensor data is enabling factories to better understand their own processes and keep them running. And putting that data into the IIoT also helps optimize how raw materials are ordered, handled and consumed. Knowing what to reorder and when can keep continuous processes at high capacity. Smart manufacturing is changing the way we make, …
Many medical devices now depend on accurate and stable pressure measurements in order tooperate reliably. What’s more, patient care is expanding beyond the hospital and the GP’s surgery and arriving in patients’ homes, in the form of home health monitoring. As a result, developing with pressure sensors has become an integral part of designing medical …
Driving would be an entirely different experience without all the pressure sensors used throughout the modern vehicle, helping to manage everything from braking to electric windows, exhaust emissions to power steering. In fact, most of the critical systems in a vehicle rely on pressure sensors to measure and monitor key parameters, which has become central …
With the continuous promotion of pressure sensor research and application fields, the substrate materials of pressure sensors are also different. It is more common to select materials with specific properties for device manufacturing. Pressure sensor base material: The substrate material is the basis for the manufacture of pressure sensors. The choice of different substrate materials …
Capacitive sensor use various types of capacitors as sensing elements to convert the measured physical quantity or mechanical quantity into a conversion device for capacitance change, which is actually a capacitor with variable parameters. A capacitive pressure sensor contains a capacitor with one rigid plate and one flexible membrane as electrodes. The area of these …
A pressure sensor is a device equipped with a pressure-sensitive element that measures the pressure of a gas or a liquid against a diaphragm made of stainless steel, silicon, etc., and converts the measured value into an electrical signal as an output. Pressure sensors are usually composed of pressure sensitive elements and signal processing units. …
