max_peak_sensor_value

– Holds the maximum sensor value. Write access resets to current value. Unit derives from 'Sen-

sor_range.unit'

– Write access resets to current value

min_peak_sensor_value

– Holds the minimum sensor value. Write access resets to current value. Unit derives from 'Sen-

sor_range.unit'

– Write access resets to current value

CAL_POINT_HI

– Highest calibrated value. For calibration of the high limit point you give the high measurement

value (pressure) to the sensor and transfer this point as HIGH to the transmitter. Unit derives

from 'Sensor_range.unit'

CAL_POINT_LO

– Lowest calibrated value. For calibration of the low limit point you give the low measurement

value (pressure) to the sensor and transfer this point as LOW to the transmitter. Unit derives

from 'Sensor_range.unit'

CAL_MIN_SPAN

– Minimum calibration span value allowed. Necessary to ensure that when calibration is done,

the two calibrated points (high and low) are not too close together. Unit derives from 'Sen-

sor_range.unit'

SCALE_IN

– Min/max-adjustment: Upper and lower calibrated points of the sensor. Unit derives from 'Sen-

sor_range.unit'

trimmed_value

– Sensor value after the trim processing. Unit derives from 'Sensor_range.unit'

sensor_sn

– Sensor serial number

temperature

– Process temperature. Selected as input to AIFB by setting 'Channel' = 4. Unit derives from

'Temperature.unit'

temperature_unit

– Unit code of 'Temperature', 'Max/Min_peak_temperature_value'

– °C, °F, K, °R

max_peak_temperature_value

– Holds the maximum process temperature. Write access resets to current value. Unit derives

from 'Temperature.unit'

– Write access resets to current value

min_peak_temperature_value

– Holds the minimum process temperature. Write access resets to current value. Unit derives

from 'Temperature.unit'

– Write access resets to current value

10.3 Dimensions

The following dimensional drawings represent only an extract of the possible versions. Detailed

dimensional drawings can be downloaded on www.vega.com under "Downloads" and "Drawings".
The two chamber housings are not available with instruments with 4 … 20 mA signal output
