DESCRIPTION

D
S
is a new generation of electronic pressure regulators designed on the basis of an enhanced digital
entronic
control.
D
S
stands for:
entronic
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
possibilities to adapt it to various applications.
The four following standard versions are available:
• With display and pushbuttons
• Without display and pushbuttons : The economic solution.
• Nominal diameter DN 4mm
• Nominal diameter DN 8mm
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 most various applications and enables the optimisation 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 serial production.
