DPS.10 | 200...1000Pa Differential Pressure Switch

Differential pressure switch, mechanical and design structure, heating, cooling, ventilation and so on. It works as a differential sensor in air conditioning systems. The differential pressure switch has passed the English definition of "Differential Pressure Switch".

In the systems where it works, it is mostly used in detecting the pollution of air filters, comparing the pollution at the inlet and outlet of the filter and transmits the data obtained to the control mechanism of the system. The differential pressure switch is used to measure whether the fans, which are the heart of the air conditioning systems, work in a healthy and desired way or the air pollution in the system. The engineering behind the differential pressure switch's ability to perform this operation is based on the effect of opposing forces on each other.

In the case of use on belts that cause problems in the operation of the system, the system is actively pumping in air or a fan or fan group that tries to extract the air inside the belt due to unwanted situations or when the belt breaks, the fans will not be able to do their job and It is used to receive the “belt broken” warning when the detected change is transmitted to the system.

Thanks to the warnings of "Belt Broken" or "System Failure", if the problem is in the area where the differential pressure switch is located, the error and problem will be detected and fixed in a short time by means of the differential pressure switch.

The working temperature values ​​of the differential pressure switch, which is a sensing element, are between -20 ileC and + 85 C, and the working pressure range is in different value ranges according to the requirements of each job. In air and air conditioning systems that require precision, having a sensitive differential pressure switch will not cause problems in the operation of the system, while the differential pressure switch is "belt broken" or the air pollution level is detected and the value is controlled, while the cost caused by a failure will be minimized.

Adjusting Differential Pressure Switch Set Value

Switchpoint or setpoint adjustment can be made with the adjustment screws located on the front of the cover where the Differential Pressure Switch is located. The graduated scales also allow relatively accurate adjustment with the set screw of the differential pressure switch, with certain tolerances

In the connections of the Differential Pressure Switch; Silicone hoses should be cut in sufficient length and assembled. In corner turns, the surface of the hose should not be stretched (short) enough to break or be long enough to get caught on something or restrict the work movement due to length.

The most reliable mounting position for the device is whether the manufacturer has chosen the vertical or horizontal position for use. When the location to be used is determined and the device reaches our hand, the cable and hose connections should remain at the bottom of the device. In this way, natural water ingress into the device due to moisture, condensation or precipitation is prevented and unwanted situations are eliminated.

While making hose connections to the Differential Pressure Switch, care should be taken to connect the high pressure side (fan outlet in fans, filter inlet in filters) to the first probe specified by the manufacturer, and the low pressure side (fan inlet for fans, filter outlet for filters) to the last probe specified by the manufacturer.The devices are only used to inform the user for air, explosive and non-corrosive gases in the specified application areas, and the intended use should not be exceeded.
