An explanation of soldering methods using automated equipment intended to assist end users with soldering Merit Sensor parts using either Pb-free solder or Pb-free containing solder.
An overview of the best methods for handing, storing and mounting Merit Sensor’s bare die pressure sensors.
Advantages and disadvantages of different pressure sensor bridge configurations and an explanation of when to use each one.
What types of pressure sensors does Merit Sensor offer? Show Answer
Merit Sensor sells MEMS Piezoresistive Pressure Sensors.
What is a Piezoresistive MEMS pressure sensor and how does it work? Show Answer
Piezoresistive literally means electromechanical. Pressure exerted on the sensor causes a mechanical deflection of the silicon diaphragm. In turn, this mechanical deflection (essentially the deformation of the crystal lattice structure of silicon) causes a change to the electrical properties or output of the implanted resistors.
What are the various pressure types? Show Answer
Gage: pressure relative to atmospheric or ambient pressure
Absolute: pressure relative to a perfect vacuum or sealed reference — zero pressure
Differential: pressure exerted on both side of the diaphragm — the difference between two pressures
Vacuum: negative pressure or pressure applied in reverse
