Device Description
parameters
Sensor 2: Sensor
Line resistance
resistance relevant for all Pt,
Ni, Cu resistance
sensor types in 2-
wire sensor
transmitter
connection type
Sensor 2: When using the
Reference transmitter
point reference point:
internally relevant
for all
thermocouples
except type B, if
thermo/equalizing
conductor is
clamped to the
transmitter
without using the
transmitter
reference point:
without type B,
externally fixed
transfer of
thermo/equalizing
conductor via
copper material
at constant
thermostat
temperature
Sensor 2: Relevant for
Reference externally fixed
point ext. reference point,
information on
constant external
reference point
temperature
Sensor 1 Parametrized
measuring range
of sensor 1 is
mapped to the
4 ... 20 mA
analog output
Sensor 2 Parametrized
measuring range
of sensor 2 is
mapped to the
4 ... 20 mA
analog output
