Design
The software of the Dräger PIR 7000 type 334 contains linearised characteristics for the
gases methane, propane and ethylene. The software of the Dräger PIR 7000 type 340
contains linearised characteristics for the gases propane and methane. With the Dräger
CC-Vision GDS software, a software based on HART
®
DD/DTM or a HART
®
handheld
terminal, the gas transmitter can be configured to any of these gases without re-calibration. In
addition, the Dräger PIR 7000 offers an internal memory for up to ten substances with
individual linearised characteristics which can be loaded additionally (for more information,
please refer to page 46).
The Dräger PIR 7000 / Dräger PIR 7200 can be switched into "fast response mode" using
the Dräger CC-Vision GDS software (or a software based on HART
®
DD/DTM or a HART
®
handheld terminal).
In standard configuration ("normal resonse mode") the measured value response time (t
0...90
)
is approx. four seconds when the measured gas concentration changes abruptly. In "fast
response mode" configuration, the measured value response time (t
0...90
) is less than one
second.
