For Short Dynamic Systems such as Power Plants
Notes
1. Control valve will close on increasing measured variable pressure
2. Regulator is to open on loss of power gas
3. VRP-SB-PID and DNGP are non-bleeding in steady state, full open & full closed position
4. Control valve shown in full open position
DNGP with Rotary Position Transmitter (Standard)
The Rotary Position Monitor is used in conjunction with the DNGP. This polarity
independent, transient protected, transmitter can operate with any voltage
from 5 to 38 volts DC. CW and CCW rotation is easily accommodated as well
as long cable runs and multiple receivers. It has an easy set up, non-interactive
adjustment, and is available in 4-20 mA. For information on installation,
calibration, and wiring diagrams please refer to appendix A of this manual.
The rotary transmitter incorporates a 1/4% precision potentiometer
specifically design for DNGP positioner.
