Corrections

Why Use Corrections

Some devices, like a thermistor, need their data corrected in order to be meaningful. A thermistor uses resistance to measure temperature. The relation between the resistance and the temperature is non linear. A thermistor uses a set of correction parameters to convert resistance to temperature. Other devices may need to correct data values in a non linear way. OMWT-SOFT-OPC provides a way for the user to correct the data from a sensor using a set of correction parameters or a lookup table.

Correction IDs

Tell OMWT-SOFT-OPC that you want a device to use a correction by specifying the Correction ID in the OMWT-SOFT-OPC.INI file. Within the device section add a line saying "CorrID=" and the number of the correction that you want OMWT- SOFT-OPC to use. The Corrections are found in the Correction.INI file that you write.

Pre-defined Thermistor

The thermistor made by the vendor Thermometrics has the part number RL0503- 5820-97-MS . This thermistor's parameters are predefined in OMWT-SOFT-OPC and given the Correction ID 128. (In the device section of the OMWT-SOFT- OPC.INI file, write "CorrID=128" to use this type.)

The parameters for the predefined thermistor are as follows:

NTC_DIVIDERES = 10000

NTC_NORMALRES = 10000

Fitting constants:

A = 3.3539264E-3

B = 2.5609446E-4

C = 1.9621987E-6

D = 4.6045930E-8
