■

13 characters total

■

Tags are adhesive or metal labels

■

Tag is permanently attached to transmitter

Software

The transmitter can store up to 32 characters for FOUNDATION Fieldbus and PROFIBUS PA or eight for HART protocol. If no characters are specified, the first eight characters of the hardware tag are the default. An optional 32 character long software tag is available when option code HR7 is ordered.

Considerations

External ground screw assembly

The external ground screw assembly can be ordered by specifying code G1 when an enclosure is specified. However, some approvals include the ground screw assembly in the transmitter shipment, hence it is not necessary to order code G1. The table below identifies which approval options include the external ground screw assembly and which do not.

Function blocks

Resource block

The resource block contains physical transmitter information including available memory, manufacture identification, device type, software tag, and unique identification.

Transducer block

The transducer block contains the actual temperature measurement data, including sensor 1 and terminal temperature. It includes information about sensor type and configuration, engineering units, linearization, reranging, damping, temperature correction, and diagnostics.

LCD display block

The LCD display block is used to configure the local display, if an LCD display is being used.

Analog input (AI)

■

Processes the measurement and makes it available on the Fieldbus segment.

■

Allows filtering, alarming, and engineering unit changes.

PID block

The transmitter provides control functionality with one PID function block in the transmitter. The PID block can be used to perform single loop, cascade, or feedforward control in the field.

Turn-on Time

Performance within specifications in less than 20 seconds after power is applied, when damping value is set to zero seconds.

Status

If self-diagnostics detect a sensor burnout or a transmitter failure, the status of the measurement will be updated accordingly. Status may also send the AI output to a safe value.

Power Supply

Powered over FOUNDATION Fieldbus with standard Fieldbus power supplies. The transmitter operates between 9.0 and 32.0 Vdc, 12 mA maximum.

Alarms

The AI function block allows the user to configure the alarms to HI-HI, HI, LO, or LO-LO with hysteresis settings.

Backup Link Active Scheduler (LAS)

The transmitter is classified as a device link master, which means it can function as a LAS if the current link master device fails or is removed from the segment.

The host or other configuration tool is used to download the schedule for the application to the link master device. In the absence of a primary link master, the transmitter will claim the LAS and provide permanent control for the H1 segment.

Hardware and Software Failure Mode

The Rosemount 644 features software driven alarm diagnostics and an independent circuit which is designed to provide backup alarm output if the microprocessor software fails. The alarm direction (HI/LO) is user-selectable using the failure mode switch. If failure occurs, the position of the switch determines the direction in which the output is driven (HI or LO). The switch feeds into the digital-to-analog (D/A) converter, which drives the proper alarm output even if the microprocessor fails. The values at which the transmitter software drives its output in failure mode depends on whether it is configured to standard, custom, or NAMURcompliant (NAMUR recommendation NE 43, June 1997) operation. Table 9 shows the configuration alarm ranges.

Performance within specifications in less than six seconds after power is applied, when damping value is set to zero seconds.

External Transient Protection

The Rosemount 470 Transient Protector prevents damage from transients induced by lightning, welding, or heavy electrical equipment. For more information, refer to the Rosemount 470 Transient Protector Product Data Sheet. Transient Protection (option code T1)

The transient protector helps to prevent damage to the transmitter from transients induced on the loop wiring by lightning, welding, heavy electrical equipment, or switch gears. The transient protection electronics are contained in an add-on assembly that attaches to the standard transmitter terminal block. The external ground lug assembly (code G1) is included with the Transient Protector. The transient protector has been tested per the following standard:

Temperature Effects Example (HART devices)

When using a Pt 100 (α = 0.00385) sensor input with a 0–100 °C span at 30 °C ambient temperature:

■

Digital temperature effects: 0.003 °C × (30 - 20) = 0.03 °C

■

D/A effects: [0.001% of 100] × (30 – 20) = 0.01 °C

■

Worst case error: Digital + D/A + Digital Temperature Effects + D/A Effects = 0.15 °C + 0.03 °C + 0.03 °C + 0.01 °C = 0.22 °C

■

Total probable error:

= 0.16 °C

Temperature Effects Examples (FOUNDATION Fieldbus devices and PROFIBUS PA)

When using a Pt 100 (α = 0.00385) sensor input at 30 °C span at 30 °C ambient temperature:

■

Digital temperature effects: 0.003 °C × (30 – 20) = 0.03 °C

■

D/A effects: No D/A effects apply.

■

Worst case error: Digital + Digital Temperature Effects = 0.15 °C + 0.03 °C = 0.18 °C
