Mortgage Calculator is not a big but very useful utility for those who are going to tie their lives to paying off a loan.

 Yes, you should think very well before taking out a loan. This is what the mortgage calculator was created for.

Enter the required data (many payment options are possible), click the "Calculate" button and you will see

how much you have to pay in total. After that, it will be easier to understand whether it suits you or not.
The program is in pdf format.

Application  PT100 ice  test was created for ship refrigeration engineers and electricians, working on refrigeration ships, carrying fruits and other products that require high temperature accuracy.
The accuracy of the sensor readings is periodically tested to achieve USDA certification.
 Sensors must be checked and calibrated prior to a USDA inspection.
To do this, make an ice test.
The readings of the sensors placed in the ice-water mixture are recorded in a special application table. After that, the program calculates the resistance values ​​of the calibration variable resistances and saves the results in a PDF file.
Detailed instructions for using the program are included in application.
This application contains several additional usefull utilities:
Temperature Converter Fahrenheit-Celsius
Pressure Converter Bar-Psi-MP
Humidity calculation for positive temperatures.
This application is suitable for almost all android devices.
You download the“apk” file and install it on your phone or tablet.

The information contained in the file will be useful for those who operate ship or industrial refrigeration plants.
We are talking about condensation pressure.
The topic is especially relevant for ship refrigeration plants.
Indeed, in navigation conditions, the temperature of the outboard water is constantly changing.
Modern automation provides for this problem.
But not all vessels are new and not all automation can cope with this task.
The solution that I put into practice on the ship  which was 25 years old is described in detail
on file. This solution provides a given condensing pressure
even with extreme fluctuations in the temperature of the intake water from 0 to 30 degrees Celsius
It will be about how to connect and configure the PID control of the SV-iP5A frequency converter to control the revolutions of the seawater pump.
Additionally, you will need a Danfoss AKS-33 pressure sensor
range from -1 bar to 20 bar
For refrigeration plants with air-cooled condensers, this may also be relevant.
