Modern pressure sensors are able to tolerate adverse temperatures, humidity and vibration conditions provided they are within design specification limits. Minimizing the effects of such conditions helps to maximize the sensor’s operational life. Temperature Most electronic prssure sensors are suitable for ambient conditions ranging from lows of –20 to –40 °C (–4 to –40 °F) …

Each pressure sensor has several aspects that will influence how it operates and the applications the pressure sensor operates best for. When choosing a pressure transducer, these six criteria should be taken into account: Application and measurement type The standard type of pressure measurement involves: Absolute, gauge, vacuum, differential, bidirectional, and sealed gage. The application …
Pressure sensor is one of the most commonly used sensors in industrial practice, which is widely used in various industrial automation environment and many other industries. In the purchase of pressure sensors, the stability of the product is a major consideration. What factors affect the stability of pressure sensors? Next, we will introduce in detail …
Factors Affecting the Stability of Pressure Sensor Read More »
Some pressure sensors are specifically designed to work with corrosive, aggressive or highly contaminated liquids and gases, collectively known as “corrosive media”. These corrosive substances will destroy or damage other substances that they come into contact with, including metals and organic compounds. This makes them difficult and dangerous to work with and raises unique challenges …
Examples of systems built around pneumatic technology include vehicle tires, air brakes (on buses, trucks and trains), air compressors, compressed-air engines, vacuum pumps and more. Examples of hydraulic applications include vehicle braking systems, power steering systems, shock absorbers, utility vehicles such as excavators and aerial platforms, lifts and industrial machinery such as hydraulic presses. The …
Water pressure sensors are often used to measure the level of water in a tank, or the rate of change in that level (as shown below). The sensor is fitted to the top of an open-ended tube submerged within the container. As the water level rises, the air above the water in the tube is …
Liquid-level monitoring plays an important role in today’s automotive, oil, water, pressure, and gas industries, to name a few. For example, pumping oil into a storage tank requires liquid-level monitoring to prevent spillage. Draining liquid out of a silo into bottles also requires liquid level monitoring for volume control. This article will explain how to …
When measuring pressurized air in other contexts, the choices include gauge pressure (air pressure compared to atmospheric pressure) and differential air pressure (pressure difference between points). Barometric pressure sensors instead measure absolute air pressure. This is the air’s pressure in relation to a perfect vacuum. Technology: For much of our history, barometers depended on the …
Optical pressure sensors detect a change in pressure through an effect on light. In the simplest case this can be a mechanical system that blocks the light as the pressure increases. In more advanced sensors, the measurement of phase difference allows very accurate measurement of small pressure changes. In an intensity-based optical pressure sensor, an …
What is capacitive pressure sensor? A pressure transducer is a device that measures the pressure of a fluid, indicating the force the fluid is exerting on surfaces in contact with it. The capacitance pressure sensor is a pressure measurement device, which converts an applied pressure into a current signal, Like 4-20mA. Capacitive pressure transducers are …
