– Offset – the parameter which allows to add or subtract a constant value to
the temperature measured by the connectors temperature sensor,
7.9.5.7. RTD measurement modules
The
RT
modules are equipped with four or six RTD inputs, see
Appendices 8.7. RT4 ,
RT6 – RTD MEASUREMENT MODULES
. These inputs are used for temperature
measurement using the RTD type temperature sensors (by two, three and four wire method)
or for resistance measurement in ranges up to 3kΩ. The RT modules cooperate with many
kinds of resistance thermometers and thanks to this there is no need to change the module
when the sensor has been changed, the user only needs to change settings in the module.
The RT modules parameters are:
–
Name
– each built-in input already has a name given by the device and the user
cannot change it, for the description of the
Name
parameter see
Fig. 7.81
,
–
Unit
– the parameter which displays
°C
or
Ω
, depending on the
Mode
parameter
settings,
– Mode – defines which sensor is used for measurement, or what is the resistance
measurement range and what is the method of these measurements (three wired
method is assigned to the separated option in the
Mode parameter e.g. Pt100 3-
wire, while two and four wired method is assigned to a different option in the Mode
parameter e.g. Pt100),
–
Low limit
– defines the measurement level below which the
Lo
state will be
displayed in the logical channel; for each sensor this limitation is different, but it can
be changed in certain limits,
– High limit – defines the measurement level above which the Hi state will be
displayed in the logical channel; for each sensor this limitation is different, but it can
be changed in certain limits,
7.9.5.8. Isolated universal inputs modules
The
UN
modules are equipped with three or five universal inputs and one input for
connectors temperature measurement, see Appendices 8.8. UN3, UN5 – OPTOISOLATED
UNIVERSAL INPUTS MODULES . It is the most advanced available module. With its help the
user can make many different kinds of measurements in each channel. This module can
measure: voltage, current, resistance, temperature using resistance sensors or
thermocouples.
The
UN
modules parameters are:
–
Name
– each built-in input already has a name given by the device and the user
cannot change it, for the description of the Name parameter see Fig. 7.81 ,
– Unit – the parameter which displays mA , V , °C, Ω or mV , depending on the Mode
parameter settings,
– Mode – allows to set the input type used for measurements,
– Low limit – defines the measurement level below which the Lo state will be
displayed in the logical channel,
–
High limit
– defines the measurement level above which the
Hi
state will be
displayed in the logical channel,
– Wire compensation – the menu which allows to compensate measurement errors
which can be caused by wrong sensor readings,
