D-ISC 100 x xx2
● Media pressure in hPa
A maximum of two "Mixed channel" software expansion modules
can be used together in a D‑ISC100, each with 4channels.
External sensors
This software expansion module is included with the device. It
makes it possible to evaluate and display signals from external
sensors (measured value transmitters). As the measured value
transmitters are connected via analogue inputs (expansion mod-
ules available as optional extras), measuring devices from ex-
ternal manufacturers can also be integrated in this manner.
The measured value signals from the connected transmitters are
converted to measured values and displayed by assigning the
source measured value (analogue inputs) to the individual chan-
nels and adjusting the signal ranges and units.
A maximum of two "External sensors" software expansion mod-
ules can be used together in a D‑ISC100, each with 4channels.
Media conditions
This software expansion module is included with the device. This
module enables the media conditions for the measured medium
(temperature and absolute pressure) to be recorded and dis-
played for the entire measurement system and to be forwarded
to all connected DURAG sensors in order to
standardise the
measured values
.
The following sources can be used as measured values for these
media conditions:
● The respective standard value (as a fixed value, standardised
measured value = measured value under operating condi-
tions).
● A measurement signal provided to an analogue input by a
measured value transmitter.
● A measured value from a connected DURAG sensor.
● A fixed value (definable).
● An external value = a corresponding measured value, for ex-
ample, one that is provided by a higher-level emissions evalu-
ation system via Modbus.
