YTK-18/02 explosion-proof pressure controller
■ Pressure controllers are suitable for measuring the pressure of hazardous fluid media and for positional (one- or two-position) control.
■ Controller is the role of elastic elements to drive the role of micro-switch pressure control instrumentation.
■ The controller has the advantages of reasonable structure, accurate action, reliable use, high frequency of opening and closing, good vibration resistance and large contact capacity.
■ Two-position controller is equipped with a device for adjusting the switching difference, so that the measured and controlled medium of the upper and lower switching value can be adjusted to the appropriate pressure control range.

The controller consists of a measuring system, a control unit, an adjusting mechanism, a housing, a plug holder, etc.
The working principle of the controller is based on the elastic deformation of the detecting element (spring tube in the measuring system) to drive the functioning element (microswitch in the control device) to produce rapid switching jump action. That is, under the pressure of the measured (control) medium, the free end of the spring tube is forced to produce the corresponding elastic displacement, and the end of the tube is connected to the micro-switch in the button (pusher) also produces the corresponding action, to be the pressure reaches the set control value of the moment, the switch contact is switched to control the system in the circuit can be disconnected or connected to achieve the purpose of automatic control and send a message.
