The Systron Donner detector operates on which principle?

Explanation:
Pneumatic detectors convert a physical input into a change in air pressure and use that pressure change to produce the readout or actuator movement. In the Systron Donner detector, a sensing element like a flexible diaphragm forms a small gas-filled chamber. When the input signal applies force to the diaphragm, it deflects, changing the volume and pressure of the trapped air. That pressure shift drives the mechanism that indicates the measurement (such as a pointer or gauge). Because the signal is carried and translated by air pressure rather than electrical resistance, light, or magnetic effects, this is classified as a pneumatic principle.
