The example shows the settings for a Pt100 sensor. The settings for Nixxx sensors
or PT1000 etc. are, however, similar.
Pt xxx
or
Ni xxx
or
YSI400
Select the resistance thermometer type used: Pt100 , Pt1000 or Ni500 etc. The
numerical values for the platinum and nickel thermometers correspond to their res-
istance at 0 °C.
YSI400 is a special NTC resistor mainly used in the medical field (temperature
range -80 to 250 °C, resistance of 1660 ... 6400
Ω).
Measuring range
Select the measurement range being used. Depending on the sensor version only
a limited range may be permissible. Refer to the sensor's technical data. The
default is always the sensor's maximum possible measuring range. The channel
receives the status ‘Measurement range overrun/underrun’ for measurements not
within the range. Channel status values are available in
status monitoring.
Temp. Format
Select the unit of measurement in which the temperature is to be displayed. Con-
version is performed automatically within the device.
°C: Degrees Celsius
K: Kelvin
°F: Degrees Fahrenheit
R: Rankine
°R: Degrees Réaumur
Scaling
Enter the valid range for sensor signals. The specified range (in the example -260
°C to +850 °C) is used as the default for the display area for graphics in ProfiSig-
nal. The channel receives the status "scale range overrun" for "scale range under-
run" when not within the range. Channel status values are available in
status
monitoring.
Connection
Indicate here how the sensor has been connected (the diagram displays the selec-
ted wiring):
2 Wire : The sensor is connected with only two wires. This is recommended only
for very short lines and high impedance sensors otherwise the resulting voltage
drop across the circuits can lead to measurement errors. Alternatively, a sensor
can be used with three connections, where measurement takes place without line
compensation.
