Wet gas generators have software:
1) built-in – the “RH Gen 01” program written in the EPROM of the device microcontroller;
2) stand-alone – the “TKA RH Generator” program (on request) for installation on a PC running Microsoft Windows.
The built-in software was developed by the manufacturer of the device to solve the problems of creating and maintaining a steam-air flow with a certain relative humidity.
The software controls the operation of the microprocessor, which ensures the functioning of the entire device and the functions of displaying the results of moisture measurements on the indicator of the device, as well as preparing them for reading by an external PC.
Standalone software is used to solve the following tasks:
– displaying information on the PC display, as well as saving the generator data in the permanent memory;
– viewing sensor signals and other diagnostic parameters.
The influence of the built-in software is taken into account when standardizing the metrological characteristics of the generators.
