Description

Instrument for conversion of a standard d.c. current
signal into a standard pneumatic signal, for the changeover

from electrical controllers to pneumatic control
valves, or from electrical measuring system to
pneumatic controllers.
The PC25 is a force balance device, which converts the input signal 4...20 mA, a proportional output signal 3..15psi (0,2...1 bar) or 6...18 psi (0,4...1,2 bar) , with a respective supply pressure of 1,7 - 5bar .

MAIN FEATURES
Particularly compact design Good dynamic response
Insensitive to mechanic vibrations
Low maintenance and low consumption
High reliability Adjustable output measuring span
