The necessary premise of using the pressure controller
Pressure controller is a corrugated diaphragm as a pressure sensitive element to drive the micro switch work table. It has the characteristics of simple and reasonable structure, various types of control, stable and reliable action, long service life, and good vibration resistance and corrosion resistance, etc.. Pressure controller is a low pressure (or vacuum) container, water tank level and similar equipment used to carry out the control of the ideal product, how to choose and install is the prerequisite for the use of the ideal product:
1, the selection of the controller is best to set the value of the set value is located in the middle of the control range of the controller settings. Generally adjust the range of 20[%]~80[%].
2, the controller should be installed in the outdoor, should be given adequate protection, so as not to be affected by the severe changes in the environment temperature, direct radiation of the sun, corrosive gas or water infiltration.
3, the installation of cables, should choose the appropriate diameter of the cable, and the cable into the tight nut tightening, so as to prevent the cable loose, and prevent the infiltration of water or dust.
4, for the pressure peak and the pulse pressure of the controlled liquid medium, can be installed on the interface of the controller in a pressure shock damper, in order to eliminate adverse effects.
5, the current can not be higher than the rated value.
6, install (or remove) the controller should pay special attention to:
1) the installation (or removal) must use a wrench to clamp the plane part of the sensor, the absolute prevention of the sensor and the switch housing relative rotation.
2) when the sensor interface is internal thread, the depth of the pipe joint can not be more than 12mm.
