266 Models - HART
Range & Span consideration
The 2600T Transmitter Specification Sheets provide all information concerning the Range and Span limits in relation to the model and
the sensor code.
The terminology currently used to define the various parameters is as follows:
URL: Upper Range Limit of a specific sensor. The highest value of the measured value that the transmitter can be adjusted to measure.
LRL: Lower Range Limit of a specific sensor. The lowest value of the measured value that the transmitter can be adjusted to measure.
URV: Upper Range Value. The highest value of the measured value to which the transmitter is calibrated.
LRV: Lower Range Value. The lowest value of the measured value to which the transmitter is calibrated.
SPAN: The algebraic difference between the Upper and Lower Range Values. The minimum span is the minimum value that can be
used without degradation of the specified performance.
TD: (or Turn Down Ratio)is the ratio between the maximum span and the calibrated span.
The transmitter can be calibrated with any range between the LRL and the URL with the following limitations:

Opening the box

Packaging content:

– Model 266 pressure (or differential pressure) transmitter
– An envelope including the multi-language short instruction manual, the calibration report and the eventual optional requested
certificates.
– An Allen key for housing rotation unlocking
– Optional content depending on the selected options:
Football adapter to ½" NPT-f and gaskets
Bracket kit
Flushing rings

Identification

The instrument is identified by the data plates shown in Figure 3.
The certification plate (ref. A): contains the certification related parameters for use in Hazardous area.
The Nameplate (ref.B) provides information concerning the model code, maximum working pressure, range and span limits,
power supply , output signal, diaphragms material, fill fluid, range limit, serial number, maximum process working pressure (PS)
and temperature (TS).
Please refer to the serial number when making enquiries to ABB service department.
The optional additional SST Tag plate (ref. C - code I2) also provides customer tag number and calibrated range. The instrument
may be used as a pressure accessory (category III) as defined by the Pressure Equipment Directive 97/23/EC. In this case, near
the CE mark, you will find the number of the notified body (0474) that have verified the compliance. 266 pressure transmitters are
in compliance with EMC 2004/108/CE*.
The certification plate (ref.A) shown here is issued by ABB S.p.A, 22016 Lenno, Italy, with the numbers:
FM09ATEX0023X (Ex d)
FM09ATEX0024X (Ex ia)
FM09ATEX0025X (Ex nL)
CE-Identification number of the notified bodies to Pressure Equipment Directive: 0474, to ATEX certification: 0722
The certification plate (ref.A) shown here may also be issued for ABB-APR, 32425 Minden, Germany, with the numbers:
FM09ATEX0068X (Ex d)
FM09ATEX0069X (Ex ia)
FM09ATEX0070X (Ex nL)
CE-Identification number of the notified bodies to Pressure Equipment Directive: 0045, to ATEX certification: 0044
*
C and F sensors on gauge and absolute pressure transmitters are in compliance with IEC61000-4-6 with B criteria
