Choosing a pressure transmitter involves more than matching the maximum process pressure to a catalogue range. The transmitter must measure the correct type of pressure, operate within a suitable calibrated span, withstand the process medium and temperature, and meet the site’s connection, communication and hazardous-area requirements.This guide explains the information to confirm before selecting an industrial pressure transmitter. It also reviews commonly used product families from Rosemount, Yokogawa, Endress+Hauser and Honeywell. The brand comparison comes after the application review because the correct measuring principle and configuration matter more than the name on the housing.
Learn how to choose the right flow meter by checking fluid type, flow range, accuracy, pressure, temperature, installation and maintenance requirements.
A valve positioner cannot be selected by brand name or input signal alone. It also has to match the actuator type, action, travel, air supply, control system and site certification requirements. If one of these details is overlooked, installation may become difficult—or the positioner may not operate the valve as expected.
This guide explains what to check before ordering a pneumatic or smart valve positioner. It also compares three widely used product families from Fisher, Siemens and ABB and shows what information is useful when replacing an existing unit.
