Cerabar PMP71B HART Technical data
Hauser 69
Linearization The device's linearization function allows the user to convert the measured value to any
units of height or volume. User-defined linearization tables of up to 32 value pairs can be
entered if necessary.

HART device variables (preset at the factory)
The following measured values are assigned to the device variables at the factory:
Device variable Measured value
Primary variable (PV)
1)
Pressure
2)
Secondary variable (SV) Sensor temperature
Tertiary variable (TV) Electronics temperature
Quaternary variable (QV) Sensor pressure
3)
1) The PV is always applied to the current output.
2) The pressure is the calculated signal after damping and position adjustment.
3) The sensor pressure is the raw sensor signal before damping and position adjustment.
The assignment of the measured values to the device variables can be changed in the
following submenu:
Application → HART output → HART output
In a HART Multidrop loop, only one device may use the analog current value for signal
transmission. For all other devices in the "Loop current mode" parameter , select the
Disable option.
Choice of HART device variables
• Pressure option (after position correction and damping)
• Scaled variable
• Sensor temperature
• Sensor pressure option Sensor Pressure is the raw signal from sensor before damping
and position adjustment.
• Electronics temperature
• Terminal current optionThe terminal current is the read-back current on terminal
block.Visibility depends on order options or device settings
• Terminal voltage 1 optionVisibility depends on order options or device settings
• Noise of pressure signal option and Median of pressure signal option Visibility
depends on order options or device settings
• Percent of range
• Loop current optionThe loop current is the output current set by the applied pressure.
Supported functions
• Burst mode
• Additional transmitter status
• Device locking
