Weather systems are monitored in a variety of different ways and with the use of various instruments. Among those instruments are barometric pressure transmitters. These instruments are used for measuring barometric pressure. Changes that can be read by a barometric pressure transmitter include weather front movement. Barometric pressure is one of the many important parameters that are monitored by weather stations. In addition, barometric pressure transmitters may also be utilized for other types of applications, including checking engine performance, ocean buoys, airports, ships, etc. Barometric pressure transmitters may also be used for determining ground and surface water level readings.
Barometric pressure transmitters can be particularly important for measuring barometric pressure, which refers to the force that is exerted by air molecules as they encounter surrounding surfaces as well as one another. This results in the weight of the atmosphere that is present over specific locations. Barometers are used for determining the measure of this weight. Barometric pressure is an element that is constantly active as well as ever changing that can vary significantly at any given time of the day and during different weather conditions.
High barometric pressure is commonly associated with calmer weather while low barometric pressure is typically associated with stormy weather. As air begins to cool, molecules begin to cluster together, resulting in denser air while also increasing pressure. When the air becomes denser, it tends to press down on the air located beneath it, resulting in warmer air. Along the same lines, when air becomes warmer, molecules begin to move away from one another and the air becomes less dense. Low pressure air results in air rising to create warm air fronts that are both volatile and fast-moving. Those warm air fronts may them pushed higher into the atmosphere by cooler air fronts located below. Varying pressure systems move in a pattern known as the Coriolis Force as the Earth rotates. This results in the atmospheric jet streams that produce varying weather patterns.
Barometric pressure is continually measured by weather stations as a way of gauging the rise and fall of air pressure for the purpose of predicting developing storms.
Commercial quality barometric pressure sensors are capable of both remote sensing and differential pressure measurement. Remote sensing means that a tube may be attached to the sensor so that pressure in a location away from the sensor may be detected. Differential pressure measurement means that a sensor can detect the difference in air pressure between two rooms. A typical use may be to ensure positive pressure is maintained in a clean room to ensure environmental contaminants are kept out.
