Proportional pressure regulator VPPM−6TA−...

3.1.1

Function

The  proportional  pressure  regulator  VPPM−6TA−...  (VPPM/
MPA)  has  been  designed  to  regulate  a  pressure  proportional
to  a  specified  setpoint  value.  An  integrated  pressure  sensor
records  the  pressure  at  the  work  connection  and  compares
this  with  the  setpoint  value.  If  the  actual  value  differs  from  the
setpoint  value,  the  pressure  regulator  is  actuated  further
until  the  setpoint  value  is  reached.

Type

Description

VPPM−6TA−...

Provides  an  analogue  input  and
an  analogue  output  with  adjust
able  pressure  unit.
