JC5125 Pressure Controller
â– Â Pressure controllers are used for measuring the pressure of fluid media without explosion hazard and for bitwise (one-position or two-position) control.
â– Â The controller is a pressure control instrument that works with the help of elastic elements to actuate microswitches.
â– Â The controller has the characteristics of reasonable structure, accurate action, reliable use, high frequency of opening and closing, good vibration resistance, and large contact capacity.
â– Â Controller according to the measured (control) object of the different, respectively, made of pressure indication and no pressure indication (each ordinary type and corrosion-resistant type)Â and other types.
â– Â The two-bit control controller is equipped with a switch for adjusting the difference so that the measured (control) media up and down the switch value is adjusted to
suitable pressure control range.
â– Â In addition, the controller also has a signal indicator to make the control circuit break or turn on at the same time to send a light signal

The controller consists of a measuring system, a controller device, an adjustment mechanism, a neon display, an indication device, and a housing and plug holder.
The working principle of the controller is based on the elastic deformation of the detection element (spring tube in the measuring system) to drive the functional element (micro switch in the controller unit) to produce a fast switching jump.
This means that the pressure of the measured (controlled) medium forces the free end of the spring tube to produce the corresponding elastic displacement, and the The push button (actuator) in the micro switch connected to the tube end also generates the corresponding action,when the pressure reaches the set control value, the switch contacts are switched, causing the circuit in the control system to be broken or turned on, and a light signal is issued at the same time to realize the purpose of automatic control and sending letters.
