What is the working principle of a frequency-type pressure transmitter? This article explains how pressure is converted into a frequency signal through the deformation of a sensing element, details its advantages in interference resistance and long-distance transmission, and provides recommendations on output methods, temperature resistance, M20×1.5 connection, PLC wiring, and selection for complex operating conditions.

Analysis of the advantages and disadvantages of pneumatic pressure transmitters: an in-depth look at their resistance to electromagnetic interference, suitability for explosion-proof applications and legacy pneumatic loops, as well as limitations such as air supply quality, response speed, and maintenance costs, helping industries such as chemicals and energy select the right model.
