Correct Pressures for Medical Procedures

Welcome to All Sensors “Put the Pressure on Us” blog. This blog brings out pressure sensor aspects in a variety of applications inspired by headlines, consumer and industry requirements, market research, government activities, and you.

Correct Pressures for Medical Procedures

Gas control, medical control systems, air compressors and vacuum pumps are all possible equipment used in a medical or even a veterinary office. In all of these systems, monitoring and controlling the pressure is necessary to achieve the proper, efficient and safe values.

While gages are commonly used so medical personnel can easily observe the pressures during a procedure, microelectromechanical systems (MEMS) sensors could easily be installed behind the panel and then communicate the data to a local or remote monitoring station. With digital data, warnings can be implemented and archived data can be used to show that proper levels of critical elements, such as oxygen, were maintained during an operation.

Media Isolated Pressure Sensors

Welcome to All Sensors “Put the Pressure on Us” blog. This blog brings out pressure sensor aspects in a variety of applications inspired by headlines, consumer and industry requirements, market research, government activities and you. In this blog we’ll be discussing media isolated pressure sensors.

Media Isolated Pressure Sensors

Unlike many other sensor applications, pressure sensors frequently have to contact some pretty nasty chemicals. Sensor manufacturers usually qualify their sensors for restricted usage with statements such as “intended for use with non-corrosive, non-ionic working fluids such as air, dry gases, etc.” This means that the user who has an application that does not meet these criteria, either cannot use a product that meets all the other application requirements or has to take steps to protect the sensor and assume any risk regarding the protection methodology.

In contrast, sensors designed specifically for harsh environments open many new applications in areas including medical, environmental controls, plant and mechanical engineering as well as automotive. In many cases, the technology changes for these more rugged sensors from a silicon, microelectromechanical system (MEMS) material to a ceramic material but still retains a monolithic design. A flush membrane makes it easy to interface these types of pressure sensors to hydraulic fluids and even extends the pressure range up to 6000 PSI. With the CPM 602 series, All Sensors now participates in these more demanding applications.

A ceramic pressure sensor overcomes many of the limitations of silicon-based MEMS pressure sensors.

New DLV Series Low Voltage Digital Pressure Sensor

Welcome to All Sensors “Put the Pressure on Us” blog. This blog brings out pressure sensor aspects in a variety of applications inspired by headlines, consumer and industry requirements, market research, government activities and you. In this blog we’ll look at All Sensors’ new DLV pressure sensor.

New DLV Series Low Voltage Digital Pressure Sensor

All Sensors has announced a new DLV Series Low Voltage Digital Pressure Sensor. The DLV Series is based on the already popular DLVR Series Pressure Sensors. This new device series offers design engineers excellent performance over middle pressure ranges of 5 to 60 psi compared to the DLVR low pressure ranges of 0.5 to 60 inH2O.

Product highlights include supply voltage options to ease application integration into a wide range of process control and measurement systems and multiple power consumption modes for battery-powered or remote systems. The DLV Series provides a calibrated and compensated output over a wide temperature range of -20°C to 85°C.

The DLV Series embodies innovative features:

  • 3.3V or 5V supply voltage
  • I2C or SPI interface
  • Better than 0.5% accuracy over temperature (typical)
  • Sil-Gel die coating is added for enhanced media protection
  • Miniature packaging with SIP and DIP lead configurations

Ideal applications for this device include:

  • Medical breathing
  • Environmental Controls
  • HVAC
  • Industrial controls
  • Portable devices/hand-held equipment
  • Other applications measuring clean, dry air and gases
