Any or all the above configurable parameters, including 

the range values which must be the same unit of measure, 

can be easily changed by a PC running the configuration 

software with DTM for 266 models.The transmitter 

database is customized with specified flange type and 

material, O–ring and drain/vent materials and meter code 

option.

Custom configuration (option N6)

The following data may be specified in addition to the 

standard configuration parameters:

Transmitter with FOUNDATION Fieldbus 

communication

Standard configuration

Transmitters are factory calibrated to customer’s 

specified range. Calibrated range and tag number are 

stamped on the tag plate. If a calibration range and tag 

data are not specified, the transmitter will be supplied 

with the plate left blank and the analog input function 

block FB1 is configured as follows:

Measure Profile Pressure

Engineering Unit kPa

Output scale 0 % Lower Range Limit (LRL)

Output scale 100 % Upper Range Limit (URL)

Output Linear

Hi-Hi Limit Upper Range Limit (URL) 

Hi Limit : Upper Range Limit (URL)

Low Limit Lower Range Limit (LRL) 

Low-Low Limit Lower Range Limit (LRL)

Limits hysteresis 0.5 % of output scale

PV filter time 0 s

Tag PI000 (up to 32 alphanumeric 

characters; only 8 visible on 

display)

Optional LCD display PV in kPa; output in percentage 

on bargraph

The analog input function block FB2 and FB3 are 

configured respectively for the sensor temperature 

measured in °C and for the static pressure measured in 

MPa.

Any or all the above configurable parameters, including 

the range values, can be changed using any host 

compliant to FOUNDATION fieldbus. The transmitter 

database is customized with specified flange type and 

material, O–ring and drain/vent materials and meter code 

option.

Custom configuration (option N6)

The following data may be specified in addition to the 

standard configuration parameters:

Descriptor 32 alphanumeric characters

Message 32 alphanumeric characters
