2. Pirani gauge - Wikipedia

   en.wikipedia.org/wiki/Pirani_gauge

   A heated metal wire (sensor wire, or simply sensor) suspended in a gas will lose heat to the gas as its molecules collide with the wire and remove heat. If the gas pressure is reduced, the number of molecules present will fall proportionately and the wire will lose heat more slowly. Measuring the heat loss is an indirect indication of pressure.

3. MAP sensor - Wikipedia

   en.wikipedia.org/wiki/MAP_sensor

   MAP sensors measure absolute pressure. Boost sensors or gauges measure the amount of pressure above a set absolute pressure. That set absolute pressure is usually 100 kPa. This is commonly referred to as gauge pressure. Boost pressure is relative to absolute pressure - as one increases or decreases, so does the other.

4. Small arms ammunition pressure testing - Wikipedia

   en.wikipedia.org/wiki/Small_arms_ammunition...

   The test cartridge must be inserted into the chamber in such a way that the hole in the test cartridge case lines up with a gas port hole that channels the gas pressure from the cartridge case to the face of the sensor. The measurement accuracy of the pressure measurements with 21st century high-pressure sensors is expected to be ≤ 2%. [7]

5. Load cell - Wikipedia

   This pressure is then transmitted to a hydraulic pressure gauge via a high pressure hose. [4] The gauge's Bourdon tube senses the pressure and registers it on the dial. Because this sensor has no electrical components, it is ideal for use in hazardous areas. [5] Typical hydraulic load cell applications include tank, bin, and hopper weighing. [6]

7. Pressure measurement - Wikipedia

   en.wikipedia.org/wiki/Pressure_measurement

   Technically speaking, most pressure sensors are really differential pressure sensors; for example a gauge pressure sensor is merely a differential pressure sensor in which one side is open to the ambient atmosphere. A DP cell is a device that measures the differential pressure between two inputs. [2]
