1 Measurement of concentration times path length, giving an
indication of the risk potential due to flammable gases and
vapours. LFL (lower flammable limit) means the same as LEL
(lower explosive limit). As an example, a concentration of 50%
LFL filling 3 metres of the beam path reads 1.5 LFLm.
2 Tag- Text that is associated with the Field Device installation.
This text can be used in any way. A recommended use is as a
unique label to a plant that correlates to a Field Device label: a
plant drawing, or on a Control System. It can also be used as a
data link layer address handle. Be aware that the HART tag is
just the first 8 characters of the 11 character tag that can be
read and set by the Pulsar Handheld terminal.
3 The unique serial number shown on the exterior label of the
Dräger Polytron Pulsar 2 Receiver, where it is prefixed by 70...
(The transmitter will have an unrelated serial number because
Dräger Polytron Pulsar 2 Transmitters of the same type can be
interchanged at will.)
4 Descriptor- Text that is associated with the Field Device. This
text can be used by the user in any way. There is no specific
recommended
5 Dräger Polytron Pulsar 2 is not intended to be used in a HART
multidrop for normal operation. However, several Pulsar
Recievers can be so connected for bench testing in the
absence of a Transmitter. Each Receiver will then be in Beam-
Block and contribute 2mA to the total signal current.
6 Date- Gregorian calendar date that is stored in the Field
Device. This date can be used by the user in any way. There is
no specific recommended use.
7 Message- Text that is associated with the Field Device. This text
can be used by the user in any way. There is no recommended
use.
8 Open Path: The gas reading expressed as a percentage of the
4-20mA range (to a maximum of 254%). Duct-mounted: the gas
reading expressed as a percentage of the 4-20mA range (to a
maximum of 254%). For the particular case of a Duct-mounted
Dräger Polytron Pulsar configured to read 0-100% LFL for 4-
20mA, this number can be read directly as %LFL
