Functionality of Pressure Transmitters:

A pressure transmitter or pressure sensor is a device used to measure the amount of pressure in a fluid or gas. They are widely used in industrial machinery as a means of warning a user before something catastrophic occurs. A pressure transmitter is recognizable as a round gauge in varying colors depending on pressure levels. Different pressure transmitters have different functions, but the type most likely found in the aviation and aerospace industries are gauge pressure sensors. These sensors can be calibrated to a variety of specific atmospheric pressures. Pressure transmitters also have multiple advantages over other types of sensors and gauges. They can withstand a massive array of environments and even be completely submerged. Made from piezoelectric materials, they are immune to both radioactive and electromagnetic fields.

FSG: Pressure Transmitters are categorized under FSG 66 - Instruments and Laboratory Equipment

FSC: Pressure Transmitters are categorized under FSC 6620 - Engine Instruments

Common Applications: Pressure transmitters have many applications in the aerospace and aviation sectors. Most important of these is to serve as a warning mechanism. When pressure levels rise to dangerous levels, the transmitter can alert the user to take action before disaster occurs. Pressure transmitters also ensure that machinery is not applying too much or too little pressure during production. As part of a greater system, pressure transmitters can be used in tandem with other parts to measure things like depth, altitude, water flow, and pressure loss. All these pieces of information are key in identifying and addressing pressure leaks.
