Pressure Transmitters

Accurate, stable process pressure measurement for safe and profitable operations — structured per Yokogawa Korea Pressure Transmitters.

Gauge Pressure (GP)

Gauge pressure transmitters compare pressure relative to atmospheric pressure.

Differential Pressure (DP)

Differential pressure (DP) is the difference between two pressures — High-side and Low-side ports.

Absolute Pressure (AP)

Absolute pressure transmitters compare pressure relative to a perfect vacuum.

Diaphragm Seal System

Used for level, density, pressure and flow measurement with remote seal assemblies.

Wireless Pressure Transmitters

ISA100-compliant wireless transmitters for DP, AP and gauge pressure.

Liquid Level

Level transmitters infer vessel level from differential pressure.

Multivariable (Mass Flow)

Multivariable pressure transmitters for mass flow measurement.

Low Pressure

Differential transmitters for very low static pressure environments.

Low Flow

Smart differential transmitters for low-flow estimation.

Hygienic Pressure Transmitters

Pressure transmitters designed for hygienic and pharmaceutical applications.
