Moniteur VPTs can be
supplied with current or resistive output that is used to determine
the precise position of the valve. This output signal can be resistive
(0-1000 ohm) or current (4-20 mA) and interfaces with most PLC
and DCS systems such as HART, Device Net, ASI and others.
Moniteur incorporates state of the art potentiometers resistant
to drift, vibration and environmental effects. As a result, feedback
signals are more stable and consistent over time, resulting in
accurate valve position indication.
Moniteur has also developed its own transmitter electronics for
enhanced reliability and resistance to environmental effects.
In addition, setting and adjusting the transmitter has been made
simple with trimming pots located on the board. |

Applications
|
| Critical
valve position applications, computer
interface, or trend analysis. The current or resistive output
option provides precise valve position indication. A continuous
analog signal in resistive or current form provides 0-100%
readout of valve position. |
| Valve
positioners and actuation equipment
that require additional or independent feedback signals. |
| Additional
monitoring of valve end-position.
Up to two mechanical or non-contact switches, or inductive
sensors can be provided in the same enclosure with the current
or resistive output electronics. |
