3. General information on the positioner
The DigiPos is an electronic positioner for pneumatically operated modulating valves. It is suitable
for membrane, piston and rotary actuators.
The DigiPos is adjusted in accordance with the respective valve during final assembly at the works
via an RS232 interface.
A commissioning software is used to this purpose for PCs with a serial interface.
This software can also be used when the system is taken into operation. During operation a
recorder function can be used to examine the behaviour of the control valve and optimise this
directly.
