P830 series pressure control

 

 

 Pressure controls are pressure-activated switches,with a basic function to make or

break an electrical circuit which in tur controls a solenoidcoil,a contactor or some other

functioning part of the system.The set point at which a control closes a contact and makes

a circuit is called the cut-in point .The point at which the control opens the switch and breaks

the circuit is called the cut-pit point.The difference between the cut-in and cut-out point is

known as the differential.

 

Features:

*P830 series pressure controls can protect compressors in refrigeration and air-condition plant, and keep

them from over-low pressure or over-high suction pressure.

*P830 series pressure controls can start and stop refrigeration compressors and fans of air condensers.            

*P830 series pressure controls can be used not only in fluoride refrigeration, but also in air and liquid.              

*P830 series pressure controls are fitted with a single pole double throw (SPDT) changeover switch.

The position of the switch is determined by the pressure control setting and the pressure at the

connector.
