Control Pressure Switch CPS 20-61

Working Range: Control Pressure switch type CPS 20-61 is useful device to control amount of pressure inside systems. This device is designed to control the pressure from 5 psi to 300 psi. This devise has ability to ON and OFF with a pressure difference (6 psi up to 50 psi) in three different ranges. The ambient temperature for this device is between -37° C till 66° C. This equipment can be fitted with 1/4 screw fitting. It is used in steam boilers, under pressure lines and etc.

Function : Function of this device is based on electro-mechanical, increasing of pressure amount inside the system that is connect to the pressure switch makes stimulation in diaphragm and the force transmitted to the leverage.at the end we have switching status in micro switch from off to on or vice versa. On the other side spring force that is connected to the adjustable screw is adjustable against of Diaphragm force.To control the balance between diaphragm force and spring force that is adjusted before there is another mechanism with another spring force that with adjusting of this spring force we can control ∆P. Then, when the pressure reaches to the ∆P set point, it will give the switch and return it to the previous state.

Installation: In cases that the temperature is lower than 110 °C pressure switch is installed vertically and directly on the system and in cases that the temperature is greater than 110 ° C it can be installed vertically on the boilers or lines with a loop (siphon). We explain it more in Installation paper.
