Corrections. Omega Engineering Dynapro ET 3200 Series, OMWT-SOFT-OPC, M-4066, OMWT Series

Predefined Corrections

The device type "Thermistor" will default to a correction ID of 128. To override this default you can add a CorrID parameter to the device section of the OMWT-SOFT-

OPC.INI file, or you can set a new default for all thermistors in the Server section of the OMWT-SOFT-OPC.INI file. To change the default CorrectionID for all thermistors add the parameter "DefaultThermistorCorrID=" to the Server section, and set it to whatever CorrectionID you wish.

Predefined Corrections use the following equations. The first equation normalizes the passed value, and the second produces the conversion to degrees Celsius.

Parameters:

NTC_DIVIDERES = 10000

NTC_NORMALRES = 10000

Fitting constants:

A = 3.3539264E-3

B = 2.5609446E-4

C = 1.9621987E-6

D = 4.6045930E-8

R normal

= NTC_DIVIDERES / (32767 / value ) - 1 / NTC_NORMALRES

Value in degrees Celsuis = 1 / ( A + B*R
