A compressor is used for the compression of gas and especially of air, for example to generate compressed air. The energy consumption and wear of the compressor can be minimized by storing the compressed gas in a pressure vessel and through the pressure control with a pressure switch. This turns off the compressor when reaching the desired pressure and turns it on again as soon as the system pressure drops below a certain level. The pressure switch thus ensures that the compressor is only running when it is actually needed and thus can extend its lifetime. In addition, this kind of switching control ensures the best energy balance of all types of compressor control. A pressure vessel with large volume reduces the number of engine switching cycles, which has a positive impact on the life time of the compressor.

Due to the excellent stability and repeatability of switching points the tecsis pressure switches are ideal for this application. Apart from the electronic pressure switches, especially the mechanical switches are suitable for compressor control since they offer not only an outstanding price-performance ratio but also a high shock and vibration resistance.

Technical Information

The individuality of the compressor control with a pressure switch is provided by the adjustment of both the switch point and the reset point. The difference between the switch-on and switch-off pressure is the so-called hysteresis of the pressure switch. This is a characteristic of pressure switches that is fixed in most mechanical pressure switches. However, the mechanical pressure switch S4250 provides an adjustable hysteresis,that can be set both at factory or by the customer on-site. Thus this mechanical switch can be optimally adapted to the requirements of the application.
