Pressure sensors are essential safety and logistic equipment in a number of underwater applications. For scuba diving, a reliable depth gauge or diving watch is crucial to estimating diving depth and ensuring safe ascent and descent. Historically, many dive watches and depth gauges have been analog designs. Digital pressure sensors have several advantages over analog […]
HVAC systems are vital when it comes to ensuring indoor air quality, health, and inhabitant comfort management.1 HVAC systems also have a central role in enhancing a building’s energy efficiency, as HVAC systems represent almost 50 % of the total energy consumption of buildings in the US and 20 % of all total energy consumption.2 Global […]
The rise in popularity and uptake of electric vehicles cannot simply be put into words; one has to look at the data. Research carried out by the International Council on Clean Transportation (ICCT) in 2017 determined that global annual electric vehicle sales were increasing nearly at an exponential rate.1 By the end of 2020, more […]
System developers who require pressure sensing capabilities where the sensor will be exposed to harsh media and extended temperature should know that packaging is critical to improve the pressure sensor’s reliability. Pressure sensors are often exposed to harsh fluids, such as gas, oil, refrigerant, and other caustic solvents that can damage the sensor’s circuitry if […]
A compact MEMS device with integrated signal conditioning is needed by many pressure sensor applications; however, the challenge is to find an approach that is capable of supporting the application’s volume and cost requirements including flexibility in terms of pressure range. From industrial to medical applications, after-market to OEM automotive high-volume projects, the solution is […]
The objective of this article is to explain the best techniques for soldering sensors manufactured by Merit Sensor using automated equipment. All profiles must be assessed and tested for best performance. Due to concerns over the safety of lead and new regulations prohibiting its use, such as the Restriction on Hazardous Substances (RoHS) Directive in […]
The value of a measurement tool is dependent on its accuracy. Measurement devices, like sensors, are found everywhere in automotive, healthcare and industrial settings. For a lot of these applications, it is necessary that the sensors are accurate to ensure quality control and guarantee patient safety. On the other hand, for Piezoresistive Pressure Sensors, this is […]
This article is aimed to describe the best methods for handling and mounting bare die pressure sensors. Merit Sensor manufactures all pressure chips on 4 inch wafers, which are sawn and delivered on Mylar film (foil tape). This foil tape is fixed to a metal wafer frame that is appropriate for the majority of automated […]
This article describes bridge configurations of different pressure sensors, when each can and cannot be used, and the pros and cons of each. Introduction Wheatstone bridge is the core of Merit Sensor’s pressure sensors and is comprised of a group of four resistors on a silicon etched diaphragm. When pressure is applied to the diaphragm, the resistors […]
Since manufacturers of medical equipment encounter constant pressures to balance cost and quality, pressure sensors present developers with contradictory requirements that can result in dangerous compromises. Pressure sensors pose a common reliability challenge that force manufacturers to depend on expensive ongoing maintenance and component replacement to work around the inherent short lifetime of the sensor.
