The indication on the fixed gear (together with the contact) gradually sets the measured value at It is indicated on the dial. At the same time, when it contacts (opens or closes) the contact (upper limit or lower limit) on the setting pointer, the circuit in the control system can be disconnected or connected to achieve automatic control and send an alarm. Purpose.

-:dd- -d>The control process is as follows: when the pressure reaches (or is low when starting up) the lower limit, the movable contact of the electric contact pressure gauge (the common terminal of the power supply) The relay is connected with the lower limit contact and operates and self-locks. Its normally open contact is closed to drive the motor and the motor is powered to run. When the pressure reaches the upper limit, the movable contact and the upper limit contact are connected to the relay > operate its normally closed contact to disconnect and cut off > supply power and its normally open point is disconnected > release the motor to stop. In this way, the purpose of automatic control is achieved.
