Compensated and Uncompensated Pressure Sensors

Take a look at Merit Sensor’s product portfolio, and you will see that the pressure sensors are available fully compensated, passively compensated, and uncompensated. Let’s briefly review the differences. When signal conditioning is used to compensate for a sensor’s non-ideal output, the sensor is considered fully compensated. When laser-trimming technology is used to change a sensor’s […]

Understanding Common Specifications for MEMS Silicon Dies

To evaluate the quality and performance of a MEMS silicon die, customers must rely on specifications, at least until they can test parts for themselves. This article will discuss the most common specifications related to these pressure-sensor dies. The primary thing to understand about MEMS dies is that when they are exposed to either pressure […]

TVC Series Pressure Sensor Internal Components

Three Common Types of Pressure-Sensor Packages

At the heart of every MEMS pressure sensor is a MEMS silicon die. Merit Sensor owns and operates a wafer fab, where it produces all of its own MEMS die. Packaging a MEMS die requires specialized equipment and skills to handle the small and sensitive die and to perform delicate wire bonding. Therefore, many customers […]

Four Characteristics of Our Newest MEMS Sensing Element

Merit Sensor has owned and operated a wafer fab from its beginnings. Fabricating our own MEMS (micro-electro-mechanical systems) sensing elements, or die, is something that sets us apart from other pressure sensor manufacturers, many of whom source their MEMS die from foundries or suppliers. Producing our own wafers, which are diced into individual MEMS sensing […]

Blood-Pressure Monitoring During the COVID-19 Pandemic

As a result of the COVID-19 pandemic, many people have been in hospitals under critical care this year. These patients require beat-to-beat blood-pressure monitoring, which helps clinicians see important vital signs about the patient in real time over the length of the critical-care treatment and make clinical decisions accordingly. Therefore, continuous, reliable monitoring of a […]
