A pressure sensor usually acts as a transducer; it generates a signal as a function of the pressure imposed. The main differences in functionality between mechanical and electronic pressure switches are the way the applied pressure is used to operate the switch, the type of switch technology, and how the switch point can be adjusted. For example: the Bourdon tube of a mechanical pressure gauge. That set pressure can either be high or low and can either engage or disengage a circuit. Variable capacitance technology is used on applications where a high degree of accuracy is paramount, such as engine test stands and pressure decay leak detection. The accurate of pressure switch is not very high, let’s make a small example, the current most popular type of pressure switch range is 0-220bar with accuracy of 5% FS. Pressure sensors are remarkably simple and highly robust. CLICK HERE to learn why HVAC systems need pressure sensors. Once given a certain pressure for example 80bar, which means the trigger condition can be alarmed anywhere between 69-91bar (5% of 220 =11, 80+11=91, 80-11=69) and the alarm may trigger at a different pressure within this range every time. Does that lead to device damage, excessive downtime or an unsafe condition ensue? This switch also tries to maintain a set pressure. Pressure switches are definitely the more simplistic and ‘old school’ technology of the two. Pressure switches have different designs with different sensing elements. You may hear electronic pressure detectors referred to as sensors, transducers, or transmitters. A transmitter on the other hand translates pressure values into currents (generally 4-20 mA) across a low-impedance load. Unlike a transducer or transmitter that can translate all of the pressures in its range, a pressure switch will trigger at a specific set pressure. ...
