1.1.5 Absolute Pressure Transmitter
Absolute stack pressure is needed to calculated velocity and standard volumetric flow. The DP
transmitter cannot continually measure stack pressure on its own. For this reason, the Deltaflow comes
standard with a 0-30 psia (61.1 inHg, 1551 mmHg) pressure transmitter. The transmitter is plumbed to
the static pressure line, and wired to input 3 of the analog module.

1.1.6 Temperature Transmitter
Stack temperature is needed to calculated stack velocity and standard volumetric flow. The probe is
equipped with a type K thermocouple to accurately measure stack temperature. The thermocouple
signal is carried down to the instrument panel via thermocouple messenger cable in the sample line
where it is terminated on a DIN rail mounted transmitter. This device converts the thermocouple signal
to a 4-20mA signal that is wired to input 2 of the analog module.
The 4-20mA output range, and input type (RTD, TC, etc.) of the transmitter is adjustable using ProSense
XT-SOFT software and a USB adapter cable (TML P/N 55000048-2).
