Intelligent pressure controller is an intelligent digital display pressure measurement and control product integrating pressure measurement, display, output and control. The product is an all-electronic structure, the front end adopts an oil-filled piezoresistive pressure sensor with a separator film, which is converted by high-precision A/D, processed by microprocessor, displayed on site, and outputs one analog and two switches.
The intelligent digital pressure controller is flexible in use, simple in operation, safe and reliable. Widely used in hydropower, petroleum, chemical, machinery, hydraulic and other industries, on-site measurement, display and control of the pressure of fluid medium.
* 100 standard instrument installation
* 4-digit LED display, regardless of value error
* On-site setting of control points
* Two control point relay outputs
* 4~20mA standard signal output(optional)
It can be directly installed on the hydraulic line through the pressure pipe fitting (M20*1.5) (other size fittings can be specified when ordering). In critical applications, such as severe vibration or shock, pressure fittings can be mechanically decoupled by micro hoses.
Note: When the range is less than 100KPa, it must be installed vertically
In order to prevent the effects of electromagnetic interference, the following should be noted:
Red V+ Yellow V- Orange OUT+ White OUT- Blue ON Green COM1 Brown ON2 Grey COM2
Fast zeroing: In the state of no pressure, long press “▲” for 3 seconds to clear to display zero (even times of operation is to restore the factory zero point).
FILt: This value is the display filter coefficient to prevent display runout due to pressure fluctuations. The larger the filtering coefficient, the more stable the display, but the more hysteresis. 0~4 optional
AL1H: This value is the switch 1 engagement value,
AL1F: This value is the switch 1 release value
AL2H: This value is the switch 2 engagement value,
AL2F:This value is the switch 2 release value
End Save to exit
Note: The switch point is determined by the absorption value and the release value configuration, when the absorption value is greater than the release value, it is the upper alarm output (normally open function), when the absorption value is less than the release value, it is the lower limit alarm output (normally closed function) The difference between the absorption value and the release value is the return difference of the switch point.
Example: To set switch point 1 as the upper limit alarm output (normally open function) at 4Mpa sink, less than 3.80Mpa disconnect; Switch point 2 is the lower limit alarm output (normally closed function) at 10MPa off, less than 9.80Mpa sink sum:
