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.

Applications for 0–5V pressure transmitters include water supply boosting, hydraulic stations, air compression systems, process pipelines, and environmental protection equipment. Learn key considerations for signal conversion, installation wiring, range and connection selection, and anti-interference performance to obtain reliable pressure measurement solutions compatible with PLCs and automation control systems.
