Water and Oil Temperature Sensor

This part is an electronic device that for example in GM and GE locomotives replaces 3 electromechanical switches T_A, T_B and T_C. It senses temperature of engine cooling water and converts it into analog pulses. But in other devices or machines can be used to sensing the direct temperature and actuate or deactivate or part or magnet valve or whatever else.

This unit that is shown in this picture actuates fans at random basis. This coincidence running fan choice causes more operational life of fans and decreases the costs of maintenance for fans.
Its operational temperature is between -40 to 120 Celsius. We have used a military microchip to stand for high temperature of engine hood.

Philosophy of Our Logo

In logo of our company, we have tried to create combination between industry and environment.

This company has been registered to work on industry and adapt it with environment (Green Industry). Our main field of activity is on railway industry. In one shot, our first goal in this company is industrial. The “Gear” is the symbol of industry and this company’s activity.

The Gear is divided into two sections. The parallel space between two half, is the symbol of railroad. Railway industry is one of the most polluter industries in the world. It contaminates atmosphere and this is our duty to find solution to adapt this polluter industry with environment and save our planet for next generations.

Green color in each half has 3 levels. As you see it begins with light green and in 3 steps becomes darker. Accretion of color level shows increase in more compatibility between industry and environment.

Our effort is to match more and more industry with environment. Therefore our logo contains three sections: Gear as symbol of Industry, Space between two half circles as symbol of Railroad and Green Color as symbol of Environment and its improvement.
