HART pressure transmitters for configuration via a distributed control system (DCS) or HART communicator.
HART pressure transmitters are compatible with the Highway Addressable Remote Transducer (HART) communication protocol which is the most popular standard used with smart field devices by the process control industry.
HART functionality enables the transfer of pressure transmitter data via an AC digital signal which uses the 4-20mA analogue output signal as a carrier, thus eliminating the need for extra wires and connectors.

Device information retrieval
What type of information can you retrieve from a pressure transmitter using HART communications?
All types of HART enabled pressure transmitters are required to include the following device information, which are retrieved using Universal Commands:
- Manufacturer name
- Product type
- Pressure value and units (Primary Variable)
- Output signal and % of scale
- Message (32 characters)
- Pressure range (Lower Range Value – LRV & Upper Range Value – URV)
- Pressure range limits (Lower Sensor Limit LSL & Upper Sensor Limit USL)
- Pressure unit
- Damping time constant
- Final assembly number
In addition to the above Universal Commands a manufacturer may also include further device information such as:
- Date
- Tag number
- Device ID
- Temperature value and units (Secondary variable)
- Software version number
User device configuration
What can you configure on a pressure transmitter using the HART coms protocol?
There are some basic operations that are essential for a user to configure in the field such as the following which are usually available via most HART communication terminals:
- Re-range LRV & URV
- Change the damping time constant value
- Set Tag number
- Change pressure units
