Pressure
A Barometer is used for measuring atmospheric pressure; which is the force extended on a single surface of unit area by the weight of the atmosphere. Barometers come in both analogue and digital, and can be used for accurate barometric measurements at room temperature or for wide ranging environmental pressure and temperature ranges. Analogue barometers are ideal for data logger applications due to their low power consumption, selectable on/off control, practical output voltage ranges and three or four wire connection capability. Some Digital barometers can have one, two or three pressure transducers. Multiple transducers provide redundancy. This is especially important for aviation or remote weather station installations.
