The PMD Series is a low- to medium-pressure sensor that uses thru-hole technology for simple mounting and soldering to a printed circuit board (PCB). It also contain a chimney that leads to the MEMS die, which simplifies the sensor’s connection to a pressure source. These design features make the PMD Series very suitable for high-volume production.

FAQ
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
