D500 / 11D micro pressure controller
The D500 / 11D pressure controller uses a diaphragm sensor, which is suitable for neutral gas and liquid media. The pressure setting is adjustable, and the switching difference is not adjustable. Can be applied to very low pressure control.
◇ Main technical performance:
Contact capacity: AC220V 2A (resistive load)
Umax380V Imax6A Pmax600VA
Working viscosity: <1 × 10-3m2 / s
Shell protection level: 1P65
Environmental temperature: -5 ～ 40 ℃
Medium temperature: 0 ～ 80 ℃
Anti-vibration performance: Avoid installing in vibration place (Maxlg) as much as possible.
Note: (1) This is the medium pressure range of the high pressure port.
(2) In actual work, the transient pressure peak of any pressure port medium cannot exceed this value.
(3) is only suitable for installation in vibration-free places.
◇ Adjustment of set value:
[Example 1]: Select a differential pressure controller with the order number 0823200, and request a contact signal when the pressure rises to 1KPa (the upper switching value).
1.1 The high-pressure inlet of the controller is screwed into the threaded interface of the calibration table, and the low-pressure inlet is empty.
1.2 Weld the cable wire to the welding piece of the micro switch, and connect the other end of the cable to the multimeter. Note: Do not use excessive force during welding to prevent the position of the micro switch from moving.
● The setting value should be selected in the middle part of the controller. If it is installed outdoors, it should be adequately protected from corrosive gases, drastic changes in ambient temperature, solar radiation, and infiltration of water. .
D520 / 11DD high-pressure medium is connected to the lower interface marked with "+", and low-pressure medium is connected to the lower interface marked with "-". D500 / 11D connects the media to the input port.
● When opening the cover, please remove the plastic cover on the micro switch and install the cover after commissioning, please be careful not to use excessive force.
● Except that you can turn the set value adjusting nut when adjusting the set value, be sure not to turn the internal parts and the mounting screw of the micro switch.
● Vibration prevention, on-off current and maximum pressure should be in accordance with the provisions of this manual.
● This controller is guaranteed for 18 months from the date of shipment.
