Description:
Pressure sensors are instruments designed to measure and convert pressure into electrical signals. The need to measure pressure intensified starting from the steam age as more hydraulic and pneumatic machines and equipment were discovered. Most
sensors are designed with a sensing element and a constant area that responds to the force applied by deflecting a diaphragm of the transducer. One of the common types of pressure sensors is the aneroid barometer model. It is designed with a hollow metal casing featuring flexible surfaces at the top and bottom. When pressure is applied, it deforms the metal casing to establish the rate of pressure.Another common category is vacuum pressure sensors that rely on heated wires with a specific electrical resistance to indicate the rate of pressure. In the case of higher vacuum range applications, cold cathode or ion sensors that rely on electrons emissions are used. Other types of pressure sensors you will get in industrial operations include manometer sensors and bourdon gauges. Make sure to look for the model and accessories that will best work with your equipment or facility.
