Pressure Sensing Elements

Pressure sensing elements are sometimes referred to as oil filled capsules, piezoresistive pressure capsules or pressure transducer capsules. The sensing element consists of a convolute diaphragm and a small amount of oil to transfer the pressure applied on the diaphragm to the piezo resistive sensing element. The oil can be silicone, or food grade depending on liquid or gas to be measured. Due to their compact size, the pressure sensing elements can be embedded into meters or measuring instruments. There are several output options including mV, amplified or digital I2C or SPI. The digital output pressure sensing elements can have a dual output of temperature and pressure and low power options are available for battery powered applications. Custom solutions can be provided.

Frequently Asked Questions About Pressure Sensing Elements

A pressure sensing element is a device or component used to measure and detect pressure in various applications. It converts mechanical force or pressure into an electrical signal for monitoring, control, or data collection.

Pressure sensing elements typically work based on the principle of deformation or displacement caused by the applied pressure. Common technologies include strain gauges, piezoelectric crystals, capacitive sensors, and resistive sensors. These elements change their electrical properties in response to pressure, allowing for pressure measurement.

Pressure sensing elements are used in a wide range of applications, including industrial automation, automotive systems, medical devices, HVAC (heating, ventilation, and air conditioning), aerospace, and consumer electronics. They are crucial for tasks such as pressure monitoring, control, and safety.

Pressure sensing elements come in various types, including strain gauge-based sensors, piezoelectric sensors, capacitive sensors, and resistive sensors. Each type has its own advantages and is suitable for specific applications.

Absolute pressure sensing elements measure pressure relative to a perfect vacuum, gauge pressure sensors measure pressure relative to atmospheric pressure, and differential pressure sensors measure the difference in pressure between two points. The choice depends on the specific requirements of the application.

Yes, some pressure sensing elements are designed to operate in harsh conditions, such as extreme temperatures, corrosive environments, or high-pressure situations. These sensors are often built with ruggedized materials and protective coatings.

Many modern pressure sensing elements come equipped with digital interfaces like I2C or SPI, making them compatible with microcontrollers and digital communication protocols for easy integration into electronic systems. Remember that the specifics of pressure sensing elements can vary depending on the type and manufacturer, so it's essential to consult the datasheets and documentation provided by the manufacturer for detailed information and guidelines on their use and maintenance.
