D500/11D micro-pressure controller adopts a diaphragm sensor and is suitable for neutral gas and liquid media. The pressure setting value is adjustable, and the switching difference is not adjustable. Can be used for very low pressure control.
◇ Main technical performance:
Contact capacity: AC220V 2A (resistive load)
Umax380V Imax6A Pmax600VA
Working viscosity: <1×10-3m2/s
Shell protection grade: 1P65
Ambient temperature: -5～40℃
Medium temperature: 0～80℃
Anti-vibration performance: Avoid installing in vibration places as much as possible (Maxlg).
Note: (1) This is the medium pressure range of the high pressure port.
(2) In actual work, the short-term pressure peak of any pressure port medium cannot exceed this value.
(3) It is only suitable for installation in non-vibration occasions.
◇ Adjustment of setting values:
[Example 1]: The differential pressure controller with the order number 0823200 is selected, and the contact signal is required to be issued when the pressure rises to 1KPa (upper switching value). The specific steps are as follows:
1.1 Screw the high pressure inlet of the controller into the threaded interface of the calibration bench, and connect the low pressure inlet empty.
1.2 Solder the cable wires to the solder lugs of the micro switch, and connect the other end of the cable to a multimeter. Note: Do not use excessive force when welding, so as to avoid the position of the micro switch from moving.
