Transducers & Pressure Transmitters

About transducers

Pressure transducers and transmitters convert process pressure into a signal for the control system, typically 4 to 20 mA with HART or a digital fieldbus. Gauge and absolute pressure transmitters measure line and tank pressure. Differential pressure transmitters measure the difference between two points, which is used to calculate flow across a primary element, level in pressurised or open tanks, and pressure drop across filters. Multivariable transmitters combine differential pressure, static pressure and temperature for compensated mass flow. The terms transducer and transmitter are often used interchangeably; a transmitter usually includes the electronics that condition the sensor signal into a standard output such as 4 to 20 mA.

This page lists 15 transmitters from Emerson Rosemount, Endress+Hauser and Yokogawa, including pressure, differential pressure and multivariable transmitters with ceramic and metal sensor diaphragms.
