1. Description
S
entronic
D
is a new generation of electronic pressure regulators designed on the basis of an enhanced digital control.
S
entronic
D
stands for:
Digital communication and control
Display (incorporated)
Direct operated valve
Dynamic behaviour (high speed)
Digital control offers many advantages during installation and start-up of the
S
entronic
D
valve and extended possibilities
to adapt it to various applications.
The four following standard versions are available:
• With display and pushbuttons:
Pressure display, manual pressure setting and diagnostic LEDs.
• Without display and pushbuttons:
The economic solution.
• Nominal diameter DN 4mm:
with a flow rate of 470 l/min (SRA).
• Nominal diameter DN 8mm:
with a flow rate of 1300 l/min (SRA).
Various pneumatic connections: integral connections, back panel connection and subbase mount.
• All pressure and exhaust ports are the same size, which allows for short response times when the pressure is
increased or decreased.
• Digital pressure control in a closed loop: An internal pressure sensor compares the setpoint at the inlet to the outlet
pressure. The outlet pressure is adjusted in real time.
• The control parameters can be changed with the additional software called
DaS
. The
DaS program
(Data
Acquisition Software) ensures that all parameters used by the valve can be changed. This flexibility allows the valve
to be adapted to the application and enables the optimization of its response time, overshoot and precision.
• After having set the optimum parameters you can save them in a project file for your personal use or send them to
our Product Support for future production.
