Pressure Transmitters

Technology differentiation between pressure transducers and pressure transmitters can be difficult to discern since they both convert a pressure signal into a desired output. For the sake of defining a transducer from a transmitter, we have defined a transmitter as a device that converts a process condition (in this case pressure) to a desired output (Foundation Fieldbus, 4-20mA, etc.) and has the ability to be ranged in the field, reconfigured in the shop, and has bus capabilities (Profibus PA, HART, Foundation Fieldbus, etc.). When selecting a pressure transmitter and accessories, consider the following: metallurgy and material compatibility with the process, pressure rating, signal type (4-20mA), pressure range and connection. Below you will find some helpful information to select the measurement or indicator that fulfills your requirements.
