Pt100 - Pt1000 Thermometers Configuration
View the analog inputs arrangement
Up on the left in the configuration window, select Pt100 or Pt1000 according to the type of sensor used.
Name
Identification name of the sensor. You can assign the name, for example, of the sensor model, or the type of measured parameter. The name should begin with a letter and can be maximum 12 characters long. The name unequivocally identifies the measurement being input; you cannot assign the same name to multiple measurements.
Unit (Unit of measurement)
Select the desired unit of measurement amongst: deg C (Celsius degrees), deg F (Fahrenheit degrees) and deg K (Kelvin degrees).
The datalogger calculates the value of the temperature corresponding to the resistance value measured, using the Callendar-Van Dusen formula for sensors with a coefficient of 0.00385, and directly records the temperature value in the chosen unit of measurement.
Channel BIP,Exc
It indicates the number of the analog input to which the sensor should be connected. The software automatically assigns the first input free. The number cannot be changed by the user.
Range
Select the desired measuring range. The options presented depend on the type
of sensor.
For sensor type Pt100 select:
±100mV for temperature measurements up to 370°C
±1000mV for temperature measurements up to 850°C
For sensors type Pt1000 select:
±1000mV for temperature measurements up to 370°C
±2500mV for temperature measurements up to 850°C
If you plan to measure temperatures not higher than 370°C it is convenient
to choose the lower range because it allows better measurement resolution.
Max Temp °C
It is the maximum temperature that can be measured with the current setting in the Range field. The value cannot be changed directly but it is calculated automatically according to the option selected in the Range field.
Error messages
If the configuration parameters are not correctly input, you can get the following error messages.
The name and Unit fields are required !
Cause: the identification name or the unit of measurement fields were not filled.
There is just an equivalent Name !
Cause: you previously entered a sensor with the same name. You should change the identification name.
